The Fourier series

Used in Physics, a Fourier series is a way to represent wave-like functions as the sum of simple sine waves. the fourier series breaks down any periodic function into the sum of an infinite set of simple oscillating functions of sines and cosines.

“A Fourier series is an expansion of a periodic function  in terms of an infinite sum of sines and cosines. Fourier series make use of the orthogonality relationships of the sine and cosine functions. The computation and study of Fourier series is known as harmonic analysis and is extremely useful as a way to break up an arbitrary periodic function into a set of simple terms that can be plugged in, solved individually, and then recombined to obtain the solution to the original problem or an approximation to it to whatever accuracy is desired or practical.“ - wolfram alpha
