Use Green's Theorem to evaluate the line integral along the given positively oriented curve: ∫_C (6y + 6e^∑x) dx + (11x + 4 cos(y²)) dy, where C is the boundary of the region enclosed by the parabolas y = x² and x = y². We note that C is a positively-oriented smooth, simple closed curve. Green's Theorem tells us that in this situation, if D is the region bounded by C, then ∮_C (P dx + Q dy) = ∬_D (∂Q/∂x - ∂P/∂y) dA.
