I need to verify the given identity. I've tried every which way i can think of, but can't figure this one out. I am self-studying this book "College Trigonometry 5th Edition by Aufmann.
This is exercise set 3.3, problem 63.
cos^2(x) - 2sin^2(x)cos^2(x) - sin^2(x) + 2sin^4(x) = cos^2(2x)
Can anyone figure this out, or is this a misprint?
Thanks for your help,
Joe
