    Areas in the Plane (Calculus)

    I can't figure out why I keep on getting the wrong answer for this problem. I would appreciate any help.

    Find the area of the "triangular" region in the first quadrant bounded on the left by the y-axis and on the right by the curves y = sinx and y = cosx

    Look at hand drawn picture below.
    They intersect at 0 and \pi/4.
    The top curve is cosine and bottom is sine:
    \int_0^{\pi/4} (\cos x-\sin x) dx
