Now, by applying Eq. (8) on Eq. (4), we can find the accurate approximate solutions for the proposed problem of the form of Eq. (1). Numerical Examples and Results To validate the applicability of the emethodsis, three examples with initial conditions have been considered. For each number of nodal points N, the point wise absolute errors are approximated by the formula, E-ly(x)-y, for i=0.1,2,.., N. where y(x) and y, are the exact and computed approximate solution of the given problems respectively, at the nodal point X. Numerical examples are given to illustrate the efficiency and convergence of the method. Example 1: Consider the following fourth order initial value problem: y=x, 0≤x≤l.
