Points at which the graphs of r = f(?) and r = g(?) intersect must be determined carefully. Solving f(?) = g(?) identifies some - but perhaps not all - intersection points. The reason is that the curves may pass through the same point for different values of ?. Use analytical methods and a graphing utility to find the intersection points of the given curves for 0 ? ? ? 2?.r = 6 + cos ?, r = 6 - sin ?
