Re: Laurent Series Expansion

Hi clumsy shark;

1)

I am unfamiliar with the terminology. To expand in a Laurent series we need the expansion around the poles. These are the zeros of the denominator.

I get for them 2 and i and -i. What happens with that ring stuff? That is where I am stuck. Do you want to expand it around 2?


In mathematics, you don't understand things. You just get used to them.
Of course that result can be rigorously obtained, but who cares?
Combinatorics is Algebra and Algebra is Combinatorics.
