Fourier Series 1.6c Description:
Fourier Series demonstrates Fourier series, which is a method of expressing an arbitrary periodic function as a sum of cosine terms. In other words, Fourier series can be used to express a function in terms of the frequencies (harmonics) it is composed of. To select a function, you may press one of the following buttons: Sine, Triangle, Sawtooth, Square, and Noise. The function will be displayed in white, with the Fourier series approximation in red. You will be able to quickly edit the function directly by clicking on it.
