What is ? What are the restictions on it? Is it ?
I've been trying out some exam questions but have become stuck on one and was hoping someone out there might be able to help me.
The question is:
Evaluate using the method of residues
So far I have that
I've tried to multiply all of this out and tidy up but the algebra is causing me problems from this point on and I was hoping you might be able to tell me where I'm going wrong.
Any suggestions would be gratefully appreciated
