We applied it to solve the fourth order initial value problem which is defined in section one. The numerical example showed that the presented spline function proved their effectiveness in solving the fourth order initial value problem. Also, we note that, the better error bounds are obtained for a small step size h.]]>Al-Bayati, A.Y., R.K. Saeed and F.K. Hama-Salh,2009Burden, R.L. and J.D.
