Question

Using power reducing formulas, how would you simply 2sin^2x when sin^2x = (1 + cos2x)/2 ?

Answer 1

can u paste a picture of the question?

Answer 2

Crap, I spotted the error I put in the question above. I'm on a mobile device so I can't post a picture, but the x is not part of the exponent. The original question is :
If sin^2 x = (1-cos2x)/2, what is 2sin^2 x?
