# d or dw

1. ### Calculation of Fourier Transform Derivative d/dw (F{x(t)})=d/dw(X(w))

Hello to my Math Fellows, Problem: I am looking for a way to calculate w-derivative of Fourier transform, d/dw (F{x(t)}), in terms of regular Fourier transform, X(w)=F{x(t)}. Definition Based Solution (not good enough): from I can find that w-derivative of Fourier transform for x(t) is...
