Modifikasi Metode Newton-Steffensen Bebas Turunan

M. Nizam M.Y


This paper develops Newton-Steffensen method involving Lagrange interpolation and the divided
difference to eliminate the derivative function and increase the order of convergence. Based of this
research is showed that the modified produce five-order convergence with efficiency index 54 1,4953
 .
Simulation numerical are given to illustrate the efiiciency and performance of the new methods in solving
nonlinier equations.
Keywords: Interpolation, Newton-Steffensen, Nonlinear Equations, Order of Convergence,
