The Wolfram Demonstrations Project contains thousands of free interactive visualizations, with new entries added daily.

The discrete Fourier sine and cosine transforms (DST and DCT) can be used to decompose or represent a given digital signal (that is, discrete) in the form of a set of sums of sines and cosines. Four transform types are possible.
