Integral tau Method for Certain Over-determined Fourth-Order Ordinary Differential Equations.

Abstract

This paper is concerned with the Integral tau methods for numerical solution of certain over determined Fourth-Order ordinary differential equations. Based on the degree of over determination and for the purpose of automation some recurrence relations were obtained. The automated Tau system obtained was tested on selected problem for the purpose of validation of the study. Numerical results further confirm that the order of the Tau approximant is also accurately estimated.
