## Homework Statement

I am trying to determine if Cauchy's integral formula will work on the following integral, where the contour C is the unit circle traversed in the counterclockwise direction.

[tex]\oint_{C}^{}{\frac{z^2+1}{e^{iz}-1}}[/tex]

## Homework Equations

See Cauchy's Integral Formula - http://en.wikipedia.org/wiki/Cauchy_integral_formula" [Broken]

## The Attempt at a Solution

I realize that there is a pole at z=0. I realize that if I could get this integral into the form

[tex]\frac{f(z)}{z}[/tex],

with f(z) being analytic in and on the contour C, then I could use the formula. However, I'm not sure how to get the integrand in that form. Is it even possible to use Cauchy's integral formula on this integral, or do I need to use a different method to evaluate this integral?
