Find the area of the region of y= cos x and y=sin2x, x= 0, x=pi/2 i sketched the curve and y=cos x is on top, so wouldn't it be \int cosx-sin2x from pi/2 to 0?

Are you sure that on ? What about ? You need to break up the integral into intervals where one function is greater than or equal to the other.
so would I have to split it into 2 integrals, one where cos x is bigger than sin2x, and the other where sin2x is bigger than cos x?
Yes. In order to do that you need to solve
