Good contour integral reference?

[quasar_4]

Can anyone recommend a good introduction to contour integrals for someone not taking complex analysis? We are doing these integrals in a physics class and I'm terribly confused. I know that I have to choose contours that "go around" my poles, but I don't understand how to do this (I can't seem to visualize it at all). I am also a bit confused on finding the residues.

Any tips/resources/infos would be great!

Thanks!
