- f(z) = An(z-z_o)^n

My homework is on mathematical physics and I want to know the concept behind Laurent series. I want to know clearly know the process behind attaining the series representation for the expansion in sigma notation using the formula that can be found on the attached files. There are three questions and I hope you will be able to help me in this subject matter. Thank you and God bless! This was retrieved from Charlie Harper's Analytic Method in Physics . Below is the formula needed, the problems, and the attempt to the solution.

On (a), I checked my answer with wolfram alpha however, my series representation (sigma notation) is wrong. Also in number 2, i got it wrong by using simple concept of geometric series. I believe item (c) is correct. Are my answers correct already?
