Homework Help: Coordinates in 3-D, Polar Coordinates, Precalculus

Posted by Cambridge on Thursday, December 19, 2013 at 8:42am.

Let a and b be real numbers. Describe the graph of r = a cos (theta + b) as much as possible. (The intent of this question is to get as specific a description as possible that holds for all possible values of a and b.)

How would I proceed on this problem? I know r = cos theta is a plot of a circle
but how would I insert a and b in there? Thanks
