Let C₁ be the line segment from the point (-4, 8) to the point (2,-4), C₂ be the arc on the parabola y = x² −8 from the point (-4, 8) to the point (2, –4), and R be the region enclosed by C₁ and C₂. Consider the vector field F(x, y) = (−y + 2 cos(2x + y), 2x + cos(2x + y)). a. Evaluate [ F · dŘ. b. Use Green's Theorem to evaluate [F. dR, where C' is the counterclockwise boundary of the region R. c. Use the results in a. and b. to deduce the value of Jai F.dR.
