    BEBERAPA METODE ITERASI ORDE TIGA DAN ORDE EMPAT UNTUK MENYELESAIKAN PERSAMAAN NONLINEAR
    (2016-02-04) Sulastri, Neli
    This article discusses the iterative method by combining two Newton’s methods where the second step of Newton’s method is given a weighted function. By pro- viding specific requirements for this weighting function, it is shown using Taylor expansion and geometric series that the iterative method have third and fourth or- der of convergence. By choosing specific weighting functions, some known iterative methods are found. Then some numerical simulations are performed to compare the number of iterations of each discussed method
