What is Fourier integral representation?
Fourier series were used to represent a function f defined of a finite interval (?p, p) or (0, L). It converged to f and to its periodic extension. In this sense Fourier series is associated with periodic functions.
What is the use of Fourier integral?
In mathematical analysis, Fourier integral operators have become an important tool in the theory of partial differential equations. The class of Fourier integral operators contains differential operators as well as classical integral operators as special cases.
The Fourier series formula gives an expansion of a periodic function f(x) in terms of an infinite sum of sines and cosines.
