Hi,
I want to compute the trigonometric fourier 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

I forgot to ask you what is the expression of x[t
where
and
now, you must split each integral into
for the [-1,0] use
for the [0,1] use
or better yet, use and change all the integrals to since we are symmetric about the y-axis
