Integral of Z^20 dz over different contours.
(a) Evaluate the line integral giving your answer in the form of a + ib, ll, be IR:.

Integral of Z^20 dz

where Cis:
i. the line segment going from z = -i to z = 1 + i
ii. the lower half of the circle Izi = 3.
(You may find using the polar- form of complex numbers useful when computing large powers.)

Thanks for the advice on the which coordinate system, but I have a suggestion as well. First, you give it a shot so the members can see where are you struggling and then provide the necessary guidance to you.

I would like to support what is said in the pevious post and remind members of MHF policy (clearly stated in the forum rules).
