Let G = (x3+ 2)7 + (ex + 6x)]. Let C be the path consisting of the line segment from (0,0) to (0,13), followed by the line segment from (0,13) to (5,13), then followed by the line segment from (5,13) to (0,0). (a) Sketch a graph of C in the xy-plane. Label important points and the orientation of the path. (b) Using Green's Theorem, set up the iterated integral that is needed to find the circulation of G around C. Do not evaluate your integral. For grading/comparison purposes, please enter only your integrand here
