Some Step Methods Applied to Nonlinear Equation

الملخص EN

In the present work, we exhibit a third order family of a new iteration method Dekker's and Classic Chord methods for solving nonlinear equations of single diode solar cell model.

These methods have free from computation of second order derivatives of the functions and per iteration, one estimation of the function; while just two evaluations involving it is first derivative.

Analysis of this family of these numerical methods investigates that it is iterative solution is convergence.

Some numerical examples are introduced to show the accuracy, efficiency and good performance of the proposed method.
