• Will do in the future didnt realize it took so long. In part C, why did u swap the integration limits?

• Not part, C, i mean for C2 you integrated from pi/2 to 0. was wondering why u did that instead of 0 to pi/2

• That is because of the orientation of the path C_2. At the initial point os C_1 we have theta=pi/2, and at the end point theta is zero. You should respect the same order in your definite integral.
