Hi,

Looking for help with this problem---I'm stumped because I get different answers than the book.

Here's the problem:

(2sin^2)(2x) = 1

The book gets the following answers: pi/8, 3pi/8, 5pi/8, 7pi/8, 9pi/8,11pi/8, 13pi/8, 15pi/8.

I keep getting pi/4, 3pi/4, 5pi/4, 7pi/4.

Appreciate an explanation of how they get the answers.
