Polar Coordinates |
1ace, 3ace, 5ace,
9, 11,
21 (just think), 23 (just think).
27, 31, 37, 43, 49, 61ad (see class notes on symmetry). On problems 27 - 49, make a chart as we did in class. |

11.2
Tangent Lines and Arc Length |
5, 13 (see the first paragraph
on page 732),
21 (find the derivative dy/dx using the chain rule, as we did in class, instead of how it is done in the Student Solution Manual of just blindly plugging into some formula that you would have to memorize), 39, 41. hint: on 39 and 41, you should graph the curve to see the range of theta required to make one revolution so you know the limits of integration. |

11.3
Area in Polar Coords |
5, 13.
Express the area as on integral with respect to theta. You do not have to evaluate the integral. (sol'n) |
