Thread: How do I use Stoke's Theorem to evaluate given this vector?

Using Stoke's Theorem, evaluate:

∫∫ (∇⋅V)⋅ dA

over any surface whose bounding curve is the (x,y) plane, where

V = (x - x²z)î + (yz³ - y²)jˆ + (x² - xz)ˆk
I'm really stuck on this particular problem, so any and all help is much appreciated. Thank you!
