In this paper, the concept of wavelet theory and more speci_cally the Legendre wavelet is reviewed. Legendre wavelet has been used for solving most of the func-tional equations. To achieve this purpose, the orthogonal polynomials and its relation with the Legendre wavelet have been introduced. The presented example shows theaccuracy of the method
