Hi,

I want to compute thetrigonometricfourier series for x[t]= e^(-|t|) from [-1,1].

The way I see it:

I need to break down the function:

for [-1,0] x[t]=e^(t)

and

for [0,1] x[t]=e^(-t)

Compute the trigo fourier for each part and add them.

I also was thinking that the function to even, I compute only the coefficients with sin with x[t]=e^(-t)??.

what is the right way of doing it?

thanks
