2. Using difference quotients, estimate f,(3, 2) and 5,(3, 2) for the function given by S(x, y) = y+1 [Recall: A difference quotient is an expression of the form (S(a + h, b) – f (a, b))/h.] 3. Use difference quotients with Ax = 0.1 and Ay = 0.1 to estimate f,(1,3) and f,(1,3), where S(x, y) = e* sin y. Then give better estimates by using Ax = 0.01 and Ay = 0.01.
