    Friday May 1

    Topics: questions on Section 5.3 problems; the Second Fundmental Theorem of Calculus
    Text: Section 5.4
    Tomorrow: exam overview; questions on Section 5.4 problems

    After much hard work to understand how definite integral is defined and how one can be evaluated directly from the definition, we arrived today at the Second Fundamental Theorem of Calculus (FTC2). FTC2 is a powerful tool for evaluating definite integrals.

    You may be wondering "What happened to the First Fundamental Theorem of Calculus (FTC1)?" There is such a thing but we have gone directly for FTC2 because FTC2 is of greater utility. FTC1 is also useful and informative but of lower priority for our purposes. I'll give you a quick look at FTC1 on Monday but not hold you accountable for it on Tuesday's exam.

    In the text's logical development, FTC1 comes first because it is easier to prove. A proof of FTC2 is then based on using FTC1. So FTC1 comes first in this logical progression. We were able to skip over FTC1 because we have not give a proof of FTC2. We have made FTC2 seem reasonable by looking at relations between flow rate and accumulation. FTC2 is both reasonable (as we've seen) and true (which we have not established in this course).

    In class, we went over some logistical details on the last week of classes and the final as listed on this handout.

    Exam #5 will be on Tuesday May 5 from 9:30 to 10:50 am. It will cover material from Section 4.8 and 5.1-5.4. (You can use the "equal-size subintervals" definition of definite integral from class rather than the more general definition from the text. The First Fundamental Theorem of Calculus will not be included.) For this exam, a well-prepared student should be able to

    Thursday April 30

    Topics: questions on Section 5.1, 5.2 problems; more on definite integrals
    Text: Section 5.3
    Tomorrow: questions on Section 5.3 problems; the Fundamental Theorems of Calculus

    Our main goals for class today were to reinforce the definition of definite integral and to look at some properties of definite integrals. The handout on defining definite integral gives a version you will be held accountable for. This is less general than the definition stated in the text.

    I've assigned problems from Section 5.3 that involve using various properties of definite integrals.

    Exam #5 will be Tuesday, May 5.

    Tuesday April 28

    Topics: building up to a definition of definite integral
    Text: Section 5.3
    Tomorrow: more on definite integrals

    A lot happened in class today. The basic plan was to

    and then Our definition of definite integral is the limit of a Riemann sum. This has parallels to our definition of derivative as the limit of a difference quotient. In each case, the definition tells us what the thing means (rate of change or slope for derivative; accumulation or area for definite integral). In each case, the definition is hard to compute. For derivatives, we developed results and rules (such as the power, product, and chain rules) so that we can now compute derivatives efficiently without resorting the definition. Note that each of the results and rules we have can be proven by starting with the definition as limit of a difference quotient. Our next task is to develop an efficient method for computing the value of a definite integral. We'll do that in class on Thursday.

    I have assigned two additional problems from Section 5.2. The last of these (Problem 37) asks you to do a calculation similar to what we did in class today.

    Monday April 27

    Topics: questions on Section 4.8 problems; more on flow rate and accumulation
    Text: Sections 5.1, 5.2
    Tomorrow: definite integrals

    In class, we looked at some plots from Friday's examples. We then began working toward more a more efficient way of representing the sums that we are building to estimate accumulation given flow rate. Our goal is to build an expression for the sum in which the number of terms is a variable. We will then be in position to think about the limit as the number of terms increases without bound.

    I've assigned problems from Section 5.1. These involve estimating accumulation or area using sums of rectangle areas. I've also assigned problems from Section 5.2 to give you practice in using the summation notation we introduced in class today. The sums in these problems are not necessarily sums of rectangle areas.

    Friday April 24

    Topics: questions on Section 4.8 problems; flow rate and accumulation
    Text: Section 5.1
    Tomorrow: questions on Section 4.8 problems; more on flow rate and accumulation

    In class, we used this handout to begin exploring the last major topic for the course. The motivation for this topic is this general problem: Given the rate of change (with respect to time) in some quantity, compute how much of the quantity accumulates over a given interval interval of time. In class, we looked at how to estimate an accumulation given limited information about the rate of change. Next week, we'll explore how to compute the exact accumulation given complete information about the rate of change.

    I have not assigned additional problems so you should continue working on the assigned problems from Section 4.8. Your goal should be to become proficient in finding basic antiderivatives.

    Thursday April 23

    Topics: antiderivatives
    Text: Section 4.8
    Tomorrow: questions on Section 4.8 problems; accumulation

    In class, we discusses antiderivatives and antidifferentiation by working through the examples on this handout. I've assigned problems from Section 4.8. I've assigned a lot of problems to give you practice in the skill of finding antiderivatives.

    Note that we will not be covering the material in Section 4.7 of the text.

    Exam #5 will be Tuesday, May 5.

    I will be available in my office this afternoon from 2:30 to 4:30. I'll also have an evening office hour from 7:30-8:30 pm in TH 374.

    Friday April 17

    Topics: questions on Section 4.6 problems; more uses of L'Hopital's rule
    Text: Section 4.6
    Tomorrow: exam overview

    In class, we looked at some extensions of and variations on L'Hopital's Rule. L'Hopital's Rule itself applies to indeterminate forms 0/0 and ∞/∞. We can use algebra or the "exp-ln" idea to manipulate other interminate forms into one of these and then apply L'Hopital's rule.

    Exam #4 will be on Tuesday April 21 from 9:30 to 10:50 am. The exam will cover material from Sections 4.1 through 4.6. For this exam, a well-prepared student should be able to

    Thursday April 16

    Topics: questions on Section 4.2 problems; L'Hopital's rule
    Text: Section 4.6
    Tomorrow: questions on Section 4.6 problems; more uses of L'Hopital's rule

    Today we looked at using L'Hopital's Rule to evaluate limits that have the indeterminate form 0/0. Tomorrow, we'll look at some variations on this basic use of L'Hopital's Rule.

    Exam #4 will be on Tuesday April 21 from 9:30 to 10:50 am.

    Tuesday April 14

    Topics: questions on Section 4.5 problems; the Mean Value Theorem
    Text: Section 4.2
    Tomorrow: questions on Section 4.2 problems; L'Hopital's rule

    In class, we discussed the Mean Value Theorem which means we've gone back to Section 4.2 in the text. There you will see reference to Rolle's Theorem. Rolle's Theorem is a special case of the MVT in which the function f is zero at both endpoints. In this case, the secant line through the endpoints has slope zero so the theorem's conclusion guarantees that there is at least one input for which the corresponding tangent line has slope zero.

    Exam #4 will be on Tuesday April 21 from 9:30 to 10:50 am.

    Monday April 13

    Topics: questions on Section 4.5 problems; the Greek alphabet
    Text: Section 4.5
    Tomorrow: a few more questions on Section 4.5 problems; the Mean Value Theorem

    In class today, we looked at problems from Section 4.5. For most of these, we started the problem but did not finish. You should work on finishing these and any other problems from the Section 4.5 assignment.

    We also took a quick look at the Greek alphabet for reference when you encounter Greek letters used as variable or parameter names.

    Words of the day: fisticuffs, kerfuffle, brouhaha, hootenanny

    Friday April 10

    Topics: questions on Section 4.4 problems; applied optimization
    Text: Section 4.5
    Tomorrow: questions on Section 4.5 problems

    I've assigned problems from Section 4.5. Some of these are more challenging. For problems that involve some geometry, start with a relevant sketch. Identity relevant variables and name them. You'll then be in better position to build the relevant relation(s) among the variables. Also identify the relevant domain for any independent variable.

    Thursday April 9

    Topics: questions on Section 4.4 problems; calculus techniques for curve sketching
    Text: Section 4.4
    Tomorrow: questions on Section 4.4 problems; applied optimization

    In class, we worked on this example of curve sketching using calculus techniques. In this type of problem, our goal is to produce a sketch of the given function's graph that shows all essential features (including values or limits at endpoints, zeros, local extremes, and inflection points). You can use a graphing calculator or other technology to plot a function graph but to do so, you must pick a specific window. Calculus techniques are useful in helping ensure you use a window that shows all essential features. In practice, most functions you encounter in applications have parameters in addition to the dependent and independent variables. Calculus techniques are a necessity for determining the essential features of a function that includes parameters.

    I've assigned a few more problems from Section 4.4. You should also finish off the problem from class today.

    Project #3 is due tomorrow.

    Tuesday April 7

    Topics: questions on Section 4.3 problems; concavity and the second derivative
    Text: Section 4.4
    Tomorrow: questions on Section 4.4 problems; putting everything together to understand all essential features on the graph of a function

    I've assigned a few problems from Section 4.4 dealing with concavity and the second derivative. I'll assign more on Thursday after we've talked about putting everything together to understand all essential features on the graph of a function.

    Project #3 is due on Friday.

    Monday April 6

    Topics: questions on Section 4.1 problems; classifying critical points
    Text: Section 4.3
    Tomorrow: questions on Section 4.3 problems; concavity and the second derivative

    We're skipping over the main idea of Section 4.2 for now, namely the Mean Value Theorem. You'll see a brief reference to the Mean Value Theorem in Section 4.3; you can ignore this reference for now.

    Project #3 is due on Friday.

    Friday April 3

    Topics: more on extreme values
    Text: Sections 4.1, 4.5
    Tomorrow: classifying critical points

    In class, we worked on the problems from this handout. The first of these is an example of applied optimization. We'll do more of this type of problem later when we hit Section 4.5. Another theme in these problems is working with functions that include parameters. Many applications of mathematics (in biology, chemistry, economics, physics, business,...) are phrased with parameters rather than specific numerical values so it is good to become comfortable in working around parameters.

    Project #3 is due Friday, April 10.

    Thursday April 2

    Topics: extreme values
    Text: Section 4.1
    Tomorrow: more on extreme values

    In class, we began looking at the problem of locating extreme values (or extrema) for a function. The text uses language that differs from what I'll use in class. What the text calls an absolute minimum or maximum, I will call a global minumum or maximum.

    Exam #3 will be on Tuesday, March 31 from 9:30-10:50 am. It will cover material from Sections 3.6-3.10 (including Euler's method). For this exam, a well-prepared student should be able to

    Today, I'll be available for office hour from 2:30-3:30. You should also be able to find me from 3:30-4:00 and 4:30-5:00 but not from 4:00-4:30.

    This evening, I'll have an office hour from 7:30-8:30 in TH 374. Depending on how many of you show up, I'll either answer questions individually or we'll get small groups working together on problems at the boards. Note: If the exterior doors to Thompson are locked, your card should work in the card reader. If you have problems with this, call Security.

    Friday March 27

    Topics: questions on Section 3.10 problems; more on differentials
    Text: Section 3.10
    Tomorrow: exam overview

    In class, we looked at examples of how to use differentials in a variety of ways, including getting a derivative from an implicit relation and for organizing the calculations in Euler's method. We can also use differentials in related rates problems. The idea there is

    You can choose how much you want to use the differentials approach in working with implicit differentiation, related rates, and Euler's method. You might want to redo some problems from Sections 3.6-3.10 in order to compare the derivative approach with the differentials approach. One significant advantage of the differentials approach is that the chain rule is done for you automatically whenever it is relevant.

    Exam #3 will be on Tuesday, March 31 from 9:30-10:50 am. It will cover material from Sections 3.6-3.10 (including Euler's method). For this exam, a well-prepared student should be able to

    Thursday March 26

    Topics: questions on Section 3.10 and Euler's method problems; differentials
    Text: Section 3.10
    Tomorrow: questions on Section 3.10 problems; maxima and minima

    In class, we looked at differentials. Here's one way to think about differentials: If two quantities, say p and q, are related to each other, then small changes in one quantity are related to small changes in the other quantity. For small enough changes, the relationship is essentially linear. We use differentials to express this linear relationship. So the relationship between the differentials dp and dq is linear. We might express this relationship as dp=a dq or as dq=b dp or as A dp + B dq=0. For example, from the relation y=x3 we get the linear relation dy=3x2 dy between dx and dy. As another example, for the relation x2+y2=1, we get the linear relation 2x dx+ 2y dy=0 between dx and dy. For x≠0, we can rewrite this as dx=-(y/x) dy. For y≠0, we can rewrite this as dy=-(x/y) dx.

    I've assigned a few problems from Section 3.10 to give you some experience in working with and thinking about differentials. Since we are too close to an exam for me to evaluate any more problems, there are none to submit.

    Exam #3 will be next week on Tuesday, March 31. It will cover material from the last half of Chapter 3 and possibly a bit of Chapter 4.

    Tuesday March 24

    Topics: linearization and uses of linearization: approximating function outputs, small angle approximation, Euler's method
    Text: Section 3.10 and Euler method handout
    Tomorrow: differentials

    In class, we discussed one use of linearization that is not discussed in the text, namely Euler's method for approximating a solution for a differential equation. Euler's method involves repeatedly approximating using linearization. We looked at one example in class from this handout.

    I've assigned problems from Section 3.10 and some additional problems on Euler's method on a handout.

    Exam #3 will be next week on Tuesday, March 31. It will cover material from the last half of Chapter 3 and possibly a bit of Chapter 4.

    Text: Sections 3.2, 3.4
    Tomorrow: questions on Section 3.2, 3.4 problems

    I've assigned problems from Section 3.4. These add trignometric functions to our mix. You should be working to become accurate and efficient in computing derivatives.

    We're skipping over Section 3.3 for now. We'll come back to this soon.

    Project #1 is due tomorrow.

    Friday February 20

    Topics: questions on Section 3.1 problems; derivative results and rules
    Text: Section 3.2
    Tomorrow: questions on Section 3.2 problems; more on derivative results and rules

    Today in class, we began developing the results and rules that will allow us to compute derivatives efficiently. All of these results and rules come from the definition of derivative as the limit of a difference quotient. Today, we used graphs to motivate most of the rules and results. Next week, we'll return to give arguments based on limits of difference quotients. For now, focus on learning to use the results and rules correctly and efficiently. This takes practice so I have assigned a lot of problems from Sections 3.2.

    A few of the problems I've assigned ask you to compute a second derivative. The idea is easy. Start with a function f. Compute the derivative to get a new function f′. Now compute the derivative of f′ to get yet another function which we denote f″ (that is, f with a double prime). We call f&Prime the second derivative of f. For example, if we start with f(x)=x3, we differentiate to get the first derivative f′(x)=3x2 and then differentiate again to get the second derivative f″(x)=3(2x)=6x.

    In class, we deduced the derivatives of the sine and cosine functions. In the text, these are covered in Section 3.4. I'll assign problems on this next week. Next week, we'll also add one more rule to our collection. This rule will allow us to differentiate a composition of two functions. The rule will allows us to differentiate a function such as f(x)=cos(x2).

    Project #1 is due on Tuesday.

    Thursday February 19

    Topics: questions on Section 3.1 problems; notation
    Text: Section 3.1
    Tomorrow: derivative results and rules

    In class, we looked at two commonly used notations for derivative. You are free to choose which to use in your own work. You'll need to be comfortable enough with both to read either in the work of others.

    I've assigned a few more problems from Section 3.1 including two problems to submit.

    In class, I mentioned that I might not be available for office hours today. As it turns, I will be available for office hour (1:30 to 2:30) and a bit beyond. I will not be available after 3:30 today.

    Tuesday February 17

    Topics: questions on Section 2.7 problems; derivative, differentiable, differentiate
    Text: Section 3.1
    Tomorrow: questions on Section 3.1 problems; more on derivatives

    In class, I distributed an overview of projects and the specific assignment for Project #1. This project is due next Tuesday.

    I've assigned problems from Section 3.1. After class on Thursday, I'll assign a few more, including some to be submitted.

    Monday February 16

    Topics: questions on Section 2.6 problems; rate of change, slope of tangent lines, the derivative; return Exam #1
    Text: Sections 2.7, 3.1
    Tomorrow: questions on Section 2.7 problems; more on the derivative

    In class, we looked at how to compute the slope of a tangent line using the limit of a difference quotient. Some of the problems I've assigned will ask you to find the equation of a tangent line. You'll need to first compute the slope, as we did in class, and then use it together with the coordinates of a point on the tangent line in the point-slope form.

    Depending on the context, the limit of a difference quotient might be interpreted as a rate of change.

    Friday February 13

    Topics: continuity
    Text: Section 2.6
    Tomorrow: questions on Section 2.6 problems; rate of change, slope of tangent lines, the derivative

    In class today, we explored the idea of continuity by working through this handout. Your first look at continuity in high school might have been based on a graphical viewpoint so that continuity is phrased as the graph of a function "having no holes" or being able to "draw the graph without lifting your pencil". With the idea of limits in hand, we can now phrase a definition of limit that does not require knowing what the graph looks like. This definition of limit is much more useful in the big picture.

    I've assigned problems from Section 2.6. You'll need to read Section 2.6 to understand a few ideas that we did not discuss explicitly in class.

    The last problem on the handout concerned finding a function that is defined for all x so that the limit of the function at a does not exist for each a. In other words, this function is defined for all x and is discontinuous for all x. The example we arrived at is the function that has output 1 if x is rational and output -1 if x is irrational. Drawing a graph of this function is difficult (or impossible). It's true that each point of the graph is either on the line y=1 or the line y=-1. But, the fact that there is an irrational value of x between any two rational values of x (and vice versa) makes the graph jump between y=1 and y=-1 in a pretty wild way.

    Thursday February 12

    Topics: Exam #1
    Text: Chapters 1-2
    Tomorrow: continuity

    Tuesday February 10

    Topics: exam overview; questions on Section 2.4, 2.5 problems
    Text: Section 2.5
    Tomorrow: Exam #1

    Exam #1 will be on Thursday from 9:30 to 10:50 am. It will cover material from Sections 1.1 to 1.6, 2.1, 2.2, 2.4, and 2.5. In Sections 2.4 and 2.5, you can ignore references to the precise definition of limit that is introduced in Section 2.3. (We'll discuss this later in the semester.) For Exam #1, a well-prepared student should be able to

    * As an example of "build a function that models a given real-world situation", think about the cost function you came up with for Problem 62 in Section 1.1.

    Here's my standard advice on how to prepare for an exam:

    I will be available this afternoon (Tuesday) for office hour from 1:30 to 3:00 and for appointments from 4:00 to 5:00. On Wednesday, I'm available for appointments from 10:00 to 11:30 and after 2:00 in the afternoon. E-mail or call (3567) if you want to set up a time to meet.

    Monday February 9

    Topics: questions on Section 2.2, 2.4 problems; increasing or decreasing without bound; vertical asymptotes
    Text: Section 2.5
    Tomorrow: exam overview; questions on Section 2.4, 2.5 problems

    Exam #1 will be on Thursday from 9:30 to 10:50 am. It will cover material from Sections 1.1 to 1.6, 2.1, 2.2, 2.4, and 2.5. In Sections 2.4 and 2.5, you can ignore references to the precise definition of limit that is introduced in Section 2.3. (We'll discuss this later in the semester.) By tomorrow afternoon, I'll post a list of specific objectives for the exam.

    Friday February 6

    Topics: questions on Section 2.2, 2.4 problems; one-side limits; limits at infinity
    Text: Section 2.4
    Tomorrow: increasing or decreasing without bound

    In class, we looked at one-sided limits and limits at infinity. Each of these is a variation of the basic idea of limit. Limits at infinity can tell us about horizontal asymptotes in the graph of a function.

    Thursday February 5

    Topics: questions on Section 2.2 problems; the limit of (sinx)/x at x=0
    Text: Sections 2.2, 2.4
    Tomorrow: one-side limits; limits at infinity

    In class, we worked through a proof of the fact that the limit of (sinx)/x at x=0 is 1. This proof uses the Sandwich Theorem. In the text, the Sandwich Theorem appears at the end of Section 2.2. The text's version of the proof we looked at is in Section 2.4 in the subsection "Limits Involving sin(θ)/θ" on pages 88-89. So, you should include that subsection in your reading about the Sandwich Theorem. I've assigned a few problems from Section 2.2 that deal with the Sandwich Theorem. I've also assigned a few problems from Section 2.4 that are related to the limit of (sinx)/x at x=0.

    We are going to skip over the material in Section 2.3 for now. We'll come back to this later in the semester. The idea in Section 2.3 is to give a precise definition of the limit of f(x) at x=0 is L. The precise definition takes some time to understand so we'll continue to work with a somewhat vague definition for now. As you read Sections 2.4 and beyond, you will occasionally see references to this precise definition of limit. You can ignore these for now.

    Exam #1 will be Thursday, February 12. I would like to see if we can use the 80-minute period from 9:30-10:50 for the exam. Note that class normally ends at 10:20 on Thursdays. I've sent out an email asking you to reply on whether or not your schedule allows you to stay for the extra 30 minutes. If you haven't already replied, please do so as soon as possible.

    Tuesday February 3

    Topics: questions on Section 2.2 problems; one application of limits: rate of change
    Text: Sections 2.1, 2.2
    Tomorrow: more on limits

    Exam #1 will be Thursday, February 12. I would like to see if we can use the 80-minute period from 9:30-10:50 for the exam. Note that class normally ends at 10:20 on Thursdays. Please check you schedule to see if you are available for the extra 30 minutes on this date.

    Monday February 2

    Topics: algebraic methods for analyzing limits
    Text: Section 2.2
    Tomorrow: why limits are important

    I've assigned additional problems from Section 2.2 including two to be submitted on Thursday.

    Exam #1 will be Thursday, February 12. I would like to see if we can use the 80-minute period from 9:30-10:50 for the exam. Note that class normally ends at 10:20 on Thursdays. Please check you schedule to see if you are available for the extra 30 minutes on this date.

    Friday January 30

    Topics: definition, results, and rules for limits
    Text: Section 2.2
    Tomorrow: more on limits

    In class today, we began moving from the somewhat tedious idea of using input/output tables to make a conjecture about a limit toward more efficient methods of evaluating limits. So far, we have a pretty limited (no pun intended) set of results and rules that allow us to evaluate "boring" limits. Next week, we'll develop some strategies that allow us to evaluate more interesting limits (typically those that involve division by 0 for x=a itself).

    I've assigned a few problems from Section 2.2. I'll assign more next week, including a few to submit.

    Thursday January 29

    Topics: questions on Section 1.5 problems; exploring more limits
    Text: Section 1.5
    Tomorrow: getting serious about limits

    Today we made the transition from review to thinking about our first calculus topic, namely limits. Before class tomorrow, you should look at as many of the problems on the "exploring limits" handout as you can. Our initial way of exploring limits by looking at lists of inputs and outputs is a bit tedious. In the next week, we'll develop more efficient ways of analyzing limits.

    Feel free to come ask me whenever you have questions on class, reading, or homework. You can also take advantage of free tutoring available from two sources:

    Tuesday January 27

    Topics: questions on Section 1.4 problems; quick review of logarithms
    Text: Sections 1.3, 1.4
    Tomorrow: questions on Section 1.5 problems

    This animation nicely illustrates the connection between the unit circle definition of sinx and the graph of sinx.

    By the end of the week, we will be done with our review of background material and ready to begin looking at calculus ideas.

    Monday January 26

    Topics: questions on Section 1.3 problems
    Text: Section 1.3
    Tomorrow: questions on Section 1.4 problems

    We'll continue our review of background material with a look at exponential functions. I've assigned problems from Section 1.4 on exponential functions. Some of this involve applications in which some quantity changes exponentially (growth or decay) in time. Come talk with me if you are not familiar with this type of application.

    Friday January 23

    Topics: questions on Section 1.2 problems; a first look at limits
    Text: Section 1.2
    Tomorrow: questions on Section 1.3 problems

    In class, we used this worksheet to get a first look at the idea of limits. Limits are a fundamental idea in calculus. After we finish our review, we'll turn our full attention to limits.

    Our next topic for review is trigonometric functions. You should read Section 1.3 and work on the assigned problems from that section. If you want more fundamentals on trigonometry, you might try working through the exercises on this handout.

    Thursday January 22

    Topics: questions on Section 1.1 problems; a bit more on real numbers
    Text: Section 1.1
    Tomorrow: questions on Section 1.1 problems

    We'll continue reviewing prerequisite ideas in class primarily by addressing questions you bring on reading and homework problems. As you read the text and work on problems, make note of any unfamiliar language and terminology. Ask questions about these by e-mail, during class, or in person outside of class.

    Tuesday January 20

    Topics: course introduction; real numbers
    Text: Section 1.1
    Tomorrow: questions on Section 1.1 problems

    As I mentioned in class, the material in Chapter 1 is mostly review of topics from high school mathematics. Everyone has a different background so there may be some topics with which you are not familiar or comfortable. We'll spend most of our class sessions this week addressing the questions you have on assigned homework. If you are feeling unsure about your mathematical background, come talk with me in the next day or two. You might also consider buying the book Just-In-Time Algebra and Trigonometry. This should be available in the bookstore.

    In class on Thursday, we'll look at questions you have on assigned problems from Section 1.1. For Problem 62 (to be submitted Friday), replace part (b) with "Use a table of values or a graph to estimate the distance x that gives the lowest cost C."

    Old exams

    You can look at exams from last time I taught Math 180. You can use these to get some idea of how I write exams. Don't assume I am going to write our exams by just making small changes to the old exams. You can use this old exam to prepare for our exam in whatever way you want. I will not provide solutions for the old exam problems.
