Hello everyone,(adsbygoogle = window.adsbygoogle || []).push({});

I need to solve an integral, opfully extracting Fourier coefficients, and I don't have a clue.

It is just

[tex]

\[

\int^{2\pi}_0 d\sigma \text{exp}{A(\sigma)}

\]

[/tex]

where

[tex]

\[

A(\sigma) = \sum_n a_n e^{-i n \sigma }

\]

[/tex]

I tried to work with complex coordinates [tex]

\[

z = e^{-i \sigma}

\]

[/tex] and look for the poles, but since there are poles at every order I can't go through that...

Any idea? I don't even know how to look on the net for something like this...

Thank you guys!
