So this equation is a liltte different from what we started with. I’ve added a normalization factor of 1/N, and changed the sign of the exponent. I also rearranged the terms slightly for clarity. This form is normally called the inverse DFT, which is confusing, but apparently the difference between the DFT and IDFT is a matter of convention, and can depend on the application. So, let’s call that close enough. Anyway, all details that are beside the main point: color is good. I absolutely agree that kids like color and coloring. Graph coloring, map coloring, coloring boards to see how to tile them there are great activities out there which reach kids who might not respond well to the normal math curriculum.
