Section 21.8 Using Technology to Calculate and Graph Fourier Transforms

UNDER CONSTRUCTION. Warning, the Sage code below currently only works for the default Gaussian function.
The code below will allow you to calculate and plot the Fourier transform of an input function of your choice. The default input function is the Gaussian \(f(x)=e^{-x^2}\text{.}\)
You might also want to try the Fourier transform calculator at Wolfram Alpha.
