Abstract

This research work is concerned with the determination of solution to different classes of problems in Ordinary Differential Equations (ODEs). We derived an ???????? - Stable rational integrators for the solution of ordinary differential equations. We establish the convergence, consistency and the stability of our scheme in the interpolants of order m = 3, through the rational integrator. The stability analysis of
the method was carried with the use of MAPLE-18 and MATLAB softwares. We compared our new and solve real-life problems which ascertain the convergence and consistency of scheme. Our result shows that our integrator is stable analytically and computationally.
