Looking Back Looking Ahead

*Areas bounded by polar curves can be calculated with definite integrals.
(EK 3.4D1)

*For a curve given by a polar equation r = f(theta), derivatives of r, x, and y with respect to theta and first and second derivatives of y with respect to x can provide information about the curve. (EK 2.2A4 (BC))
