Let I be the contour given by the square with vertices 2+ 2i, –2+2i, –2 – 2i and 2 – 2i, oriented positively and traversed once. Evaluate the following integrals: (a) (3 points) Sr cos z dz z(z²+8) e-z dz (b) (4 points) Sr (z-in/2)" where n is a positive integer (c) (4 points) Jr 2-1 P(2) dz where P is a polynomial function Let I be the contour given by the square with vertices 2+ 2i, –2+2i, –2 – 2i and 2 – 2i, oriented positively and traversed once.
