Hey guys, got a polar curve symmetry problem, any help appreciated.
1. Test the polar curve r = 2cosu - 1. Then accurately graph. <-- the problem is, I don't know for sure if it's r = 2cos(u - 1) or r = 2cos(u) - 1. Sorry about that.

Hello,
I've attached a diagram of both curves:
1. the first equation is a circle (red)
2. the second equation is some kind of a cycloid curve (black).
From your post I assume that you have to examine some symmetry properties. So it looks like as if #2 is a very good candidate for such an examination.
