## Homework Statement

Find the Fourier series for e

^{x}for x in (-1,1).

Find the Parseval identity.

## Homework Equations

## 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!
