8. (1 credit Let C be the portion of the circle x = V72 - y2 from the point (0, -7) to the point (0, 7). Also, let F(x, y) = sin (y)i + (x cos (y) - sin (y) ) j. Find the work done on F on a particle moving around C using any method at your disposal. Hint: There are at least three roads to success on this problem, and one road that will absolutely lead to despair...)
