Answer the following:

Let F(x, y) = (2x + e – y cos? x, xel + sin y). Let C1 be the path from (0,0) to (7,0) along
the x-axis, and let C, be the path from (7,0) to (0,0) along the graph of y = sin r.
(a) Evaluate the line integral F. dR.
C1
(b) Let C = C¡ U C2. Use Green's Theorem to evaluate
(c) Use the results in parts (a) and (b) to find the amount of work done by
F in moving an object along C2.
