### Complex Analysis

In this thread, f is assumed to be a function mapping complex numbers to complex numbers, unless it is explicitly stated otherwise.

Hi;

In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.

Thanks for the answers and method.

### Re: Complex Analysis

No problem, I can post the solutions to others if you would like. #6 is basically a generalisation of the method used in post #14.

### Re: Complex Analysis

Update: Have started making video solutions to the problems. A solution to #1 has been recorded.

### Re: Complex Analysis

I've also added a video solution for #6, for n = 8. The case for general n is done in exactly the same way (that is, the idea of choosing a contour that encloses just one of the poles).
