Numerical solution of fifth-order boundary-value problems in off step points

Non-polynomial sextic spline in off step points is used to solve special fifth order linear boundary value problems. Associated boundary formulas are developed. We compare our results with the results produced by non-polynomial sextic spline method [10]. However, it is observed that our approach produce better numerical solutions in the sense that $hbox{max}|e_{i}|$ is a minimum.
