Numerical Treatment of General Third Order Ordinary Differential Equations Using Taylor Series as Predictor

This work considers the direct solution of general third order ordinary differential equation. The

method is derived by collocating and interpolating the approximate solution in power series. A

single hybrid three-step method is developed. Taylor series is used to generate the independent

solution at selected grid and off grid points. The order, zero stability and convergence of the

method were established. The developed method is then applied to solve some initial value

problems of third order ODEs. The numerical results of the method confirm the superiority of the

new method over the existing method.
