Metode Iterasi Tiga Langkah Bebas Turunan Untuk Menyelesaikan Persamaan Nonlinear
This thesis discusses a derivative free three-step iterative method to solve a
nonlinear equation using Steffensen's method, after approximating the derivati-
ve in the method proposed by Abro and Shaikh [Appl. Math. Comput.,55(2019),516-
536] by a divided difference method. This study shows analytically that the
method is of order sixth under a condition and for each iteration it requires
three function evaluations. Numerical comparison show that the new method
is comparable to the other sixth order method discussed.
Keywords: Steffensen's Method, derivative-free method, nonlinear equation, order of convergence, sixth order
