    Green's Theorem HELP!

    1) Use Green's Theorem to evaluate integral of surface C [(x^2 + y^2)dx + (xy^2)dy where C is the closed curve determined by y^2 = x and y = -x with 0 <= x <= 1

    I cant find out the condition for the integrals.
    what i got is:

    int (0 to 1) int (? to ?) [ y^2 - 2y dy dx]

    Please Help!

    The region is bounded by the line y=-x and the parabola x=y^2, and thus is in the fourth quadrant. For the order of integration in question, you have the outer integral's limits right. For the inside, recall that your limits will be your y as a function of x, and examining the order, you see that at a given x, y ranges from -\sqrt{x} to -x. Graphing the region in question will help make this more clear.
