(a) integral(xdy-ydx)

(b) integral((x^2)dy)

(c) integral((y^2)dx)

So for:

(a) integral(xdy-ydx)= double integral(2)dA what are the bounds?

(b) integral((x^2)dy)= double integral(-2x)dA what are the bounds?

(c) integral((y^2)dx)= double integral(2y)dA what are the bounds?

I know how to evaluate all the double integrals, I just don't know the bounds. I'm assuming I would use parameterization.

I think the answer for (a) is (pi/2)*ab, for (b) is (2/3)*(a^2)b, and for (c) is (-2/3)*a(b^2), but I solved them directly from a line integral not Green's Theorem.

Thank you.
