Hi,
New to the site...just wondered if any one could help me on a question regarding Residue Theorem/Laurent Series.
I'm trying to solve an integral:
{integral C) (e^z + 6z)/(z^3 + z^2 - 2z) dz
where C = {z: |z - 0.5| = 1}
So: I have factorised the denominator to give:
(e^z + 6z)/(z (z-1) (z+2)) and now I get stuck trying to form the Laurent Series of the function...in order to get the Residue.
Any help would be much appreciated...
Cheers
Nick
