Hi,

I'm trying to do a similar question http://www.mathhelpforum.com/math-he...ng-180323.html but getting quite confused. Can you explain how you got the singularities and how then you apply the residue theorem. I'm thinking the singularities for my problem are (2a^2)e^3iPi/4 and (2a^2)e^iPi/4 which is like yours, I don't know how to go about wirking out the residue etc after this! Any help advice you could offer would be appreciated!
