Fourier analysis

Frequency-domain graphs

Fourier analysis began with trying to understand when it was possible to represent general functions by sums of simpler trigonometric functions.

The attempt to understand functions (or other objects) by breaking them into basic pieces that are easier to understand is one of the central themes in Fourier analysis.

Fourier analysis is named after Joseph Fourier who showed that representing a function by a trigonometric series greatly simplified the study of heat propagation.
