Hi guys~

I have got a few things about some fourier transform Q/A that i wanted to check...so here you go:

1) Find the fourier sine and cosine transform of f(x)=x 0<x<3

ok, for the sine, i get -9/n∏ but i get zero for cosine part, is it wrong?

and the second one:

find the fourier transform of f(x)=x^2 -2<x<2

i know that we use the exponential (e^-inx) here and the answer i get is almost right but its just that i get 'i's along with my answer. How do i correct that??
