Calculus 2 Lecture Notes, Section 9.7

You should be able to plot the conic sections given in polar form, and convert the rectangular forms of their equations to polar and parametric forms. Theorem 7.1: Eccentricity of the conic sections. The set of all points whose distance to the focus is the product of the eccentricity e and the distance to a directrix is: An ellipse for 0 < e < 1. ................
