I need to calculate the residue of
( 1 - cos wt ) / w^2
This has a pole of second order at w=0, am I correct?
Now may math book says that a second order residue is given by
limit z goes to z_0 of {[(z-z_0)^2. f(z)]'} where z_0 is the pole
I'm quite new to complex analysis. Could someone perhaps show me how this relates to the above, and how I get the residue from this?
Cheers!
