    [SOLVED] Area between a curve

    given curves f(y)=y(2-y) f(y)=-y
    I graph the curves as y=x(2-y) and y=-x rotated 90 degrees clockwise.

    This is the setup for the the integral.
    A= integral [right-left]
    <br />
\int_{-3}^0(y(2-y)-(-y))dy<br />

    but When I solve I end up with a negative value

    your limits of integration should be from 0 to 3 ... note the graph
