This is multivariable calculaus question, please I need the answer to be hand-written. Please no guessing if you don't know don't answer

(Part A is two points; Part B is four points.) Given So(y - sin(a) )da + cos(x) dy, where C is the triangle with vertices (0, 0), (7/2, 0), and (7/2, 1) and its orientation is counterclockwise. Part A. Which method would be the efficient (least amount of headaches) to solve the above question: using line integrals directly or Green's theorem? Explain why. Part B. Solve the
