Homework Help: Precal

Posted by Mayhem on Saturday, February 25, 2012 at 2:46am.

How do you find all the polar coordinates of P=(-1, -2pi/3)? I've read that you're supposed to add 2pi to find the coterminals but when I do that I get different answers then in the book. The book answer is (1, 2pi/3+ (2n+ 1) pi) and (-1, -2pi/3+ 2npi). How in the world do you get those answers?
