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.
