    Area of enclosed region

    Find the area of the region enclosed by y=sin2x and y=cosx for -pi/2 < x < pi/6? (INCLUSIVE INTERVAL)

    do i just take the integral of the top minus the bottom?

    Not yet, you need to find out if they intersect on the given interval first.

    Do they? i.e. solve \sin 2x = \cos x
