1. Suppose that S is a positively-oriented (or outward-oriented) closed cylinder of radius R and finite height h. (a) Determine div F, where F = (xy, y + z, x - yz). (b) Use the Divergence Theorem to compute the flux of F across S (Hint: you should not need to actually compute a triple integral here - instead, think about what it represents).
