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. - May 22nd 2011, 03:48 PMdorkymichelle
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
