Half Range Series

  1. Mar 7, 2015 #1
    If we have a standard function like x or x^2 defined between 0 and pi. Then why should we be interested in extending this function to give a Fourier series which resembles this function between 0 and pi? What is the whole purpose of this process? Does it have any real life application or is it just a mathematical exercise?

    A sawtooth waveform is something you can observe in an oscilloscope and hear (if you run it through an audio amplifier). Between 0 and π it looks just like the function y = x.
