Problem 8. Consider the differentials below. For each of the cases above, determine if df is an exact, or inexact differential. If the differential is exact, determine the function f(x,y). (Recall that a differential is exact if it can be written a "derivative" of a single-valued function.) (a) df = xy dr +ry² dy. (b) df = r* dx + cos(y)dy. (c) df = y dz – dy. (d) df = (yda – e dy). (e) df = (3rº + y)do +(3y2 +1)dy.
