Anyhting that involves Fourier is gay. Everyone knows this. But...

Got the a0 term:Quote:

Compute the Fourier series representation of

f(x) = exp(ax), -pi <= x < pi.

(sinh(a*pi))/(a*pi)

For an and bn i just keep going roun in circles for the integration by parts and splitting it up with different limits, evena nd odd functions etc isnt helping :(

Any ideas?
