Homework Statement
Find the Fourier series for ex 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 cn are the coefficients of the Fourier series.
I tried plotting
[tex]\sum_{k=-\infty}^{\infty}c_{n}e^{i n x}[/tex]
together with ex and it doesn't seem to be correct...
Thank you for your help!
