Each plot below show part of the graph of the implicit equation given in the specified problem from Section 3.6. Each plot also shows a tangent line at some specific point on the graph. You can compare your result from the derivative dy/dx you calculate with the slope of the tangent line that is shown.
Problem 7. The tangent line is shown at (2,2). |
Problem 9. The tangent line is shown at (0,0). |
