    What have you tried so far? Have you written down the definition of the Fourier transform for these functions? If so, can you manipulate those integrals so as to make them look more like the Fourier transform of f?

    is it correct if i write exp(+ix*omega)f~ (where f~ is the fourier transfer of f(x))
    and how can you please guide me on how to get the fourier transfer of derivative of f

    Write out the integral for this FT, and use integration by parts.

    Lononeer . . . you know about Mathworld right? Me, I'd do a BookMark/Mathworld/Fourier Transform - scroll down, scroll down . . . bingo-bango.
