FouSE-Fourier Series Expansion




    This app helps in the learning of Fourier series expansions. It has an easy-to-use, friendly interface, and can be viewed as a tool to help undergraduate students test and assess the Fourier series expansions on typical set of signals, such as:
    -- Sawtooth;
    -- |\sin| (full wave rectified);
    -- Half sin (half wave rectified);
    -- Square;
    -- Triangle;
    -- Parabolic (t^2).
    Some of its main characteristics include the ability for the students to control the total approximation error and the number of terms/harmonics used in the expansion.

    This app shows the results of adding successive harmonics to an approximation of a waveform, but not the coefficients or how they are found. I would like to see a slider at each harmonic to allow the user to see what the correct coefficient should be. It might also be nice to see (maybe in Help) the calculation to find the correct coefficient.
