During our math methods lecture yesterday, this pair of formulas came up:

Which was very cool because it has the feel of a Fourier series. It's a sum that approximates a function... The coefficients are line integrals over the contour as opposed to integrals over the conjugate variable. This is the last in a string of similarities between complex analysis and Fourier analysis that have been building in class lately. So, it was very cool to find a set of class notes from

Dr. Jeffrey Rauch of UMich that directly addresses this:

Thanks Dr. Rauch!
