Metode Iterasi Bebas Turunan Berorde Delapan Optimal Untuk Menyelesaikan Pers…

This thesis discusses a derivative free three-step iterative method to solve a nonlinear equation. The proposed method is derived by estimating the first de-rivative of the method proposed by Sharma and Arora [Appl. Math. Comput., 273 (2016), 924-933] using a divided difference by one parameter. Analytically it is shows that the method has an eighth order convergence and requires four function…
