Need help finding the fourier transform of xe^-x

  1. Jun 1, 2014 #1
    Can anybody help in in finding the Fourier transform of f(x) = xe^-x where -1<x<0 and f(x)= 0 otherwise?

    The range of x is missing a lower limit.

    Oh sorry, the range of x is -1 < x < 0.

    What's the definition of the Fourier transform of a function f(x)?

    SteamKing is trying to get you to try to do this problem yourself. He knows the definition of a Fourier transform, but we want to see how you would approach this problem.
