Three Steps Second Derivative Adams Moulton Methods for the Solution of Stiff Differential Equations

D. J. Zirra, Y. Skwame & D. Gideon · Journal of Scientific Research and Reports · 2018

In this paper, the continuous forms of the Second Derivative Generalized Adams methods (SDGAMs) and its hybrid formed by adding one off-grid collocation point for step number k = 3 were derived. These continuous formulations were evaluated at some desired points to give the discr...

Computational Method for the Simulation of Duffing Oscillators

J. Sunday, D. J. Zirra & S. E. Gandafa · Advances in Research · 2017

A one-step computational method is proposed for the simulation of Duffing oscillators in this research. In achieving this, power series was adopted as a basis function in the derivation of the method. The integration was carried out within a one-step interval, where the interval...
