A Fourier series is a way of representing a periodic function as a (possibly infinite) sum of sine and cosine functions. It is analogous to a Taylor series , which represents functions as possibly infinite sums of monomial terms.

He initialized Fourier series, Fourier transforms and their applications to problems of heat transfer and vibrations. The Fourier series, Fourier … The Basics Fourier series Examples Fourier series Let p>0 be a xed number and f(x) be a periodic function with period 2p, de ned on ( p;p). The Fourier series of f(x) is a way of expanding the function f(x) into an in nite series involving sines and cosines: f(x) = a 0 2 + X1 n=1 a ncos(nˇx p) + X1 n=1 b nsin(nˇx p) (2.1) where a 0, a n, and b 2 days ago The Fourier Series is a shorthand mathematical description of a waveform. In this video we see that a square wave may be defined as the sum of an infinite number of sinusoids. The Fourier transform is a machine (algorithm). It takes a waveform and decomposes it into a series of waveforms.
