10.1 #1-25 odd,33,35,37,41,45, 49,51,53 26,34 Thursday Aug 30 A useful algebraic step in 49 and 51 is to complete the square
Plane Handout #1-7 8 Friday Aug 31 9 and 10 are just a bit more challenging -- try them
9.4 #1-9,11,17,21,31,33 28 Tuesday Sep 4
10.6 #1-12,35,37,39,43 42 Friday Sep 7 For 42 (to be submitted) include sketches of cross-sections and at least an attempt at sketching the entire surface.
12.1 #1,3,7,9,13-18,19,25, 35,39 28 Monday Sep 10
12.2 #1,3,9,11,13,15,21,25, 27,29,31,33,35,37,45,47 None None
12.3 #1,5,7,11,13,15,17,23,25, 29,31,37,39,43,47,51, 55,69,73,75 None None
12.4 #1,3,7,9,13,17,39,42,47,49 None None
10.2 #1-23 odd,25,29,33,39,41, 43,45,49,51 50 Thursday Sep 20 A median in a triangle is the segment from a vertex to the midpoint of the side opposite that vertex. For Problem 49(c), use the fact that the medians of a triangle all intersect at a point that is two-thirds of the way along each median.
10.3 #1-7 odd,9,13,15,21,23, 24,28 18 Monday Sep 24
Planes Handout #2 #1-5 4 Tuesday Sep 25
11.1 #1,3,7,9,15,23 26 Thursday Sep 27
11.3 #1,3,17 8 Friday Sep 28 For Problems 1, 3 and 8, just find the length of the given curve. For 17(a), you can find an equation for the plane by finding the points on the curve for t=0,π/2,π,3π/2 and then using these to compute \(m_x\) and \(m_y\).
12.5 #1,3,5,7,9,13,15,17,19, 27,29,36 18,32 Thursday Oct 4
Gradient Handout # 1,2 None None
12.6 #9,11,25,27,29,33,37,39 40 Friday Oct 5
Differentials Handout #1-7 6 Friday Oct 5 The problem to submit is #6 on the handout which is the same as #48 in Section 12.6.
12.7 #11,21,25,27,29,31,35, 42,43,46 None None The directions for problem #42 use the word "imagining". It is more accurate to use the word "visualizing".
Applied Optimization Handout #1-6 None None
12.8 #3,10,11 5 Tuesday Oct 23
Applied Optimization Revisited #2,4 None None You should redo these problems using the method of Lagrange multipliers and then compare this solution method with your original solution method.
Nonuniform density Handout #1,2,3,5 4 Thursday Oct 25
13.1 #3,7,9,13,15,17,21,23 None None
13.2 #3,9,17,25,29,33,35,37,47 None None
Area Density Handout #1-5 None None #5 uses polar coordinates. Work it after we review them.
9.1 #3,5,7-21 odd,23,29,41 None None
9.2 #1,13,21,33,34 None None Now work #5 from the area density handout
13.4 #3,9,11,17,21,29,31(a) 30 Monday Nov 5
13.5 #5,11,17,25,29,35,39 36 Monday Nov 5

13.7 #21,31,33,41,49,65,81 66 82 Thursday Nov 8
Volume Density #1-5 None None
Integration Over Curves #1,2,3,5,7,8,9 8 None For an optional challenge, try numbers 4 and 6.

This same material is covered in Section 14.1 of the text using parametrizations rather than "zooming in". For another optional challenge, try Number 11 on page 855. Think of the fucntion \(f(x,y,z)=xy+y+z \) as a length charge-density function.
