In this paper, we present a new secant-like method for solving nonlinear equations. Analysis of the convergence shows that the asymptotic convergence order of this method is 1 + โ 3. Some numerical results are given to demonstrate its efficiency.

โฆ Synopsis
In this paper, a new method for solving nonlinear equations f(x) = 0 is presented. In many literatures the derivatives are used, but the new method does not use the derivatives. Like the method of secant, the first derivative is replaced with a finite difference in this new method. The new method converges not only faster than the method of secant but also Newton's method. The fact that the new method's convergence order is 2.618 is proved, and numerical results show that the new method is efficient.
