Tell me about Laurent series...

[elendil]

Hi. I need to know about Laurent series amongst other things. I've read a bunch about it, but I need a good example, so I'll ask you to find the laurent series of

cos z / z^4

and explain what you're doing a long the way. Presume you're dealing with a mathematical fool, if you please

I've picked this function as I already have an example of it as a pdf, but it's a bad, bad scan of bad, bad handwriting, so I can't make out most of it :/

Sincerely,

-Kenneth Straarup.

I have a nice several thousand page book that covers it, yes I'd just really like a step-by-step example of the above to really understand it.

It's like programming. You can read so much about a programming language, but an included example does heaps in regards to understanding what you've read.

Sincerely,
