Hey guys here's the problem...

Suppose f is a differentiable function of x and y, and g(u,v) = f(e^u + sinv, e^u + cosv). Use the table of values to calculate gu(0,0) and gv(0,0).

At (0,0): f = 3, g = 6, fx = 4, fy = 8

At (1,2): f = 6, g = 3, fx = 2, fy = 5

Where fx and fy and f sub x and f sub y (partial derivatives).

My problem is, I can't figure out how to differentiate g(u,v) with respect to x or y. Any insight?
