Abstract:The aim of this paper is numerical solution of some IBVPs with various boundary conditions. Here, we approximated some second order IBVPs using Legendre special function expansion. Then, we use Legendre polynomials on the interval [-1, 1] as the basis functions (i. e. shape or approximation functions) for collocation method. We also evaluate conditions that can give better approximations, then present some examples of different boundary conditions and finally our approximate solutions are compared with its analytic solution.
