Hello everyone,
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!
