    What is the Fourier Transform of t*f(t)

    So there isn't a theorem where I can simply put 2 transforms function together?! Hi Tachyon, is this what you mean? 1. ∫t*e^-2t^2 e^-iwt dt 2. -2t^2-iwt = -2(t^2+iwt/2) = -2[(t+iw/4)^2+w^2/16]=-2(t+iw/4)^2 -(w^2)/8 as I let p=t+iw/4 therefore dp=dt 3. ∫t*e^((-w^2)/8)dt +∫e^(-2p^2) dp...

    What is the Fourier Transform of t*f(t)

    Homework Statement f(t)=t*e^(-2t^2) Find the Fourier Transform F(w) of f(t). It is given that when f(t)=e^[(-at^2)/2] F(w)=√(2*pi/a)*e^[(-w^2)/2a] Homework Equations The Attempt at a Solution The transform of e^(-2t^2) is easily obtained from the given information, and I got...
