I'm trying to do a trigonometric type contour integration... one with limits of integration between -Pi and Pi. Is there a rule about what the integrand has to look like?(adsbygoogle = window.adsbygoogle || []).push({});

Eg can I do this (I've converted it into z's):

int( f(z)/( (z-z1)^2 (z-z2)^2 ) ,z)

...can f(z) be any function?

And is it okay for the original limits to be from -Pi to Pi rather than the normal 0 to 2*Pi

Thanks!
