Summary

DescriptionFourier Series Square Wave.svg	English: The first four terms of the Fourier series of a square wave, $\psi (x)={\frac {4}{\pi }}\sin(\pi x)$ $+{\frac {4}{3\pi }}\sin(3\pi x)$ $+{\frac {4}{5\pi }}\sin(5\pi x)$ $+{\frac {4}{7\pi }}\sin(7\pi x)+\ldots$ $=\sum _{{\text{odd }}n=1}^{\infty }{\frac {4}{n\pi }}\sin(n\pi x)$ . This variation of file:Fourier_Series.svg is color-blind friendly, displays the math, and emphasizes standing waves on a string. And, after making this image, I noticed File:Fourier series and transform.gif, which can either replace or accompany File:Fourier series and transform.gif.
