(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Find the Fourier series for e^{x}for x in (-1,1).

Find the Parseval identity.

2. Relevant equations

3. The attempt at a solution

[tex]c_{n}=\frac{1}{2}\int_{-1}^{1}e^{x}e^{-i n x}dx[/tex]

Where c_{n}are the coefficients of the Fourier series.

I tried plotting

[tex]\sum_{k=-\infty}^{\infty}c_{n}e^{i n x}[/tex]

together with e^{x}and it doesn't seem to be correct...

Thank you for your help!
