Evaluate each of the following contour integrals. Use whatever method is appropriate, such as direct computation, fundamental theorem of calculus (use an antiderivative), Cauchy-Goursat theorem, principle of deformation of paths, Cauchy integral formula, or extended Cauchy integral formula.
(i) ∫(Kp dz), C is the line from 0 to ≥3+1.
(ii) ∫(Jc 7+Td), C is the positively oriented square with vertices 2, 2 + 2i, -2 + 2i, -2.
(iii) ∫(Jc 22 944), C is the positively oriented square with vertices 2, 2 + 2i, -2 + 2i, -2.
(iv) ∫(Jo:" +2) d, Let C be the octagon formed by connecting the Sth roots of unity with line segments. Then C is the contour from exp(in/4) which traverses sides of C clockwise.
(v) ∫(dz), C is the unit circle |z - 1| = 1, positively oriented (n is a positive integer).
