Abstract
this paper presents a new double-approximate computational method for solving Fredholm integral equations of the second kind. The method is based on the approximation of the given data function, and the unknown function by utilizing Legendre polynomials in matrix form, while the approximate function of Legendre coefficients of the first approximation of the kernel is expanded once again using Legendre polynomials. In addition, the double substitution of the unknown function into the considered integral equation provides access to a linear system of an algebraic equation, which is equivalent to the required solution. Convergence in the mean of the unknown function is proved. Finally, five illustrative examples are presented. It turns out that the obtained approximate solutions converge to the exact solutions that demonstrate the authenticity and the efficiency of the new method.
Keywords
