Metode Iterasi Empat Langkah Optimal Dengan Konvergensi Orde Delapan

This final project discusses a family of four-step iteration method with six parameters which requires three function evaluations and one derivative function evaluation. Analytically it is showed that the iterative method has the optimal order of convergence eight, with the efficiency index is 1:682 which is optimal according to Kung and Traubs conjecture. Numerical comparisons shows that …
