On the Comparison of Adam-Bashforth and Adam Moulton Methods for Non-Stiff Differential Equations

Osakwe Charles Nnamdi, Olobayo Solomon Adelaja & Omowo Babajide Johnson · Asian Research Journal of Mathematics · 2022

This paper presents the comparison of the two Adams methods using extrapolation for the best method suitable for the approximation of the solutions. The two methods (Adams Moulton and Adams Bashforth) of step k = 3 to k = 4 are considered and their equations derived. The extrapol...
