Solve the boundary value problem

Abstract

Abstract:
This paper studies the boundary value problem from the second order, using
three methods ; Rayleigh-Ritz method, collocation method, and Galrekin – at
the same example suppose the solution is approximate function for
polynomial function of third and fourth degree, we noted that, when the
degree increased the accuracy increased too, the collocation method is easy to
apply, and Rayleigh-Ritz method and Galerkin methods are better accuracy.
