1. Suppose that S is a positivelyoriented (or outwardoriented) closed cylinder of radius R and nite height h. (3) Determine div 1:", where I; = (my, y + z, 3.\": 9'2). (13) Use the Divergence Theorem to compute the ux of F across S (Hint: you should not need to actually compute a triple integral here instead, think about what it represents)
