1. The problem statement, all variables and given/known data
I have uploaded necessary image(s) for the question

I have successfully accomplished a, but I am not sure how to start b.

2. Relevant equations

The sum of the integral paths added up = the desired result.
3. The attempt at a solution

And then go along the line R--> p
and then the circle Cp
And back along the line p-->R

How do I represent this? It will take 4 integrals added together, correct?

The integral over CR is |z|=R ?
Over line 1: z=re^(i2pi), p=<r=<R

Not sure how to set up these bounds. After I get the bounds, I should know how to solve it, I think.

Also, If there any examples of similar problems that use the entire circle as the contour (and not the half circle) that would be helpful to me.

Not trying to be pushy, but I have to turn this assignment in in a few hours. Was wondering if anyone was around for some quick help. :)
