Vector Calculus
My given problem is as follows: Given that rho = x^2 + xy, calculate
integral rho dS over the region y <= x^2, 0 < x < 1.
I'm not sure how to set up the integration. I don't understand how to use the
y <= x^2 info as far as setting up an integral. The text I'm using is horrible in terms of lack of examples and numerous errors. I could use some help.

There's a very nice tutorial on multiple integration sticked to the upper topics in this forum section, here's the link:
