What is the Inverse Fourier Transform

What is the inverse Fourier transform and what are its applications? Here we discuss a very elegant way of "undoing" what the Fourier transform does. In other words, can you always find a function whose Fourier transform is a given function f? We will see that the answer is "yes" under most circumstances. We will use this for example to find the inverse Fourier transform
