Fourier inversion of function

  1. Jul 18, 2015 #1
    Hi all.
    I have to do Fourer inversion of an equation 7.46 but I don't know how to do that.
    If anybody has any idea it wolud be very helpfull.
    Inversion of S(q) is G(r).

    Is this homework help?

    No. I'm learning some physics and need to calculate this to get next step, but i can't. :/

    Did you try Wolfram Alpha?

    I can't see the whole problem, plus it is sideways.

    No, didn't. That is whole problem, to do Fourier inverse of 7.46. Sorry because it is sideways. :/

    I have used Wolfram Alpha and got (almost) same result as I calculated earlier. (See pic) But in my book I have r instead of k in denominator. And that result in the book is fundamental! It must be correct. Where have Wolfram and me failed?
