Abstract

This article introduces two approaches to
develop block methods for solving second order ordinary differential equations
directly. Both approaches, namely a new linear block approach and the modified
Taylor series approach are capable of producing a family of methods that will
simultaneously approximate the solutions of any ordinary differential equation
at the respective grid points of the block method. The computational
complexities of both approaches are examined, and the results show the new
linear block approach require less computations compared to the modified Taylor
series approach.
