Show that theorem 7.1 is true, and then convert the Cartesian equation to polar form. Assume that the . focus. is at the origin, and the directrix is at x = d > 0 (Note: shifting the origin of the coordinate system to the focus is a common practice for many central force problems, because this is the location of the central force; i.e., the sun ... ................
