#5: Use Green's Theorem to evaluate the following integral, (er + 28,3) dox + ( 6y' - 28x) ) dy where C is the curve that starts at the origin, and then goes along a straight line to the point (V7, V.7), and then along the arc of the circle x2 + yz = 14 from the point (V7, V7) to the point (0, V14), and then along a straight line back to the origin
