Metode Iterasi Orde Delapan Dengan Indeks Efisiensi Tinggi Untuk Menyelesaika…

This final project presents the use of a weight function to derive a new family of eight-order method for finding a simple root of nonlinear equations. Per iteration the method requires three function evaluations and one first derivative function evaluation so that the efficiency index of the method is 1.682. Numerical comparisons using some test functions indicate that the method can be u…
