Metode Iterasi Tiga Langkah Tanpa Turunan Dengan Taksiran Beda Terbagi Untuk Menyelesaikan Persamaan Nonlinear
This article discusses an iterative method to solve a nonlinear equation, which is free from derivatives, obtained by approximating a derivative in the method proposed by Rhee et al. [Int. J. Comput. Math., 95 (2018), 2174-2211] by the method of divided difference. We show analytically that the method is of order eighth and for each iteration it requires four evaluation functions. Numerical experiments show that the new method is comparable with other discussed methods.
Keywords: Efficiency index, derivative-free method, divided difference, order of convergence
