    METODE ITERASI ORDE LIMA MENGGUNAKAN FUNGSI BOBOT DAN BASINS OF ATTRACTION
    (Elfitra, 2023-11) Oktarina, Oktarina
    This article discusses a two-step iterative method for solving nonlinear equations. This method is obtained by modifying Newton’s method using a weight function. Analytically, it is shown that using Taylor expansion and geometric series, this iter- ation method has a convergence order of five and requires four function evaluations for each iteration. This fifth order iteration method has an efficiency index of 1.495. Numerical computations show the new method is comparable to other fifth-order methods discussed. This article also discusses basins of attraction, namely a visual depiction of the dynamic behavior of an iteration method for nonlinear equations from various starting points.
