I'm looking for help finding the Fourier Transform for the function cos(2\(\pi\)x) + cos(8\(\pi\)x)

This is meant to be a simple exercise to introduce Fourier transforms usage in image processing, however I have never seen a Fourier transform before so I thought seeing an example might help. This is not suppose to result in complex integrals but merely encourage the use of simple properties of transforms to solve.

 

Welcome to the forum,

Here's a link, you should be able to get going with it after reading the web page: -
