    MODIFIKASI METODE CAUCHY DENGAN ORDE KONVERGENSI EMPAT
    (2017-01-10) Elisabet, Masnida Esra; Putra, Supriadi
    This article discusses two modification of Cauchy’s method by using Taylor’s expansion of second and third order to solve nonlinear equations. Both methods have order of convergence four and need three function evaluations per step, so that theirs efficiency index is 1.587. Furthermore, the computational results show that the methods converge faster in obtaining a simple root of the nonlinear equations compared to Newton and Cauchy’s method.
