Fourier Series Visualization

How it Works

The Fourier Series allow a representation of any periodic function as a sum of sine waves.

  • Each rotating circle is an "epicycle" representing one term (a sine or cosine wave) in the series.
  • The final point's path draws the resulting waveform.
  • Increase the "Number of Terms" to add more waves and better approximate the target waveform.
