Hi, I got a problem in which I have to find the Fourier Transform of a function f(t) defined:
f(t) = { 1 - |t|, |t| < 1
0, |t| > 1 }
Well , I found the Fourier transform by working out the integral f(t)e^(-iwt) with the limits being -inf to +inf (and I got the right answer).
Now, since f(t) is an even function, does that mean I can use the Fourier cosine transform?
I tried to work it out and got a different answer, and basically I'm confused?
Any help is appreciated, thanks!
