Abstract

Some local convergent derivative-free methods are suggested for solving nonlinear scalar equations. The error equations are given theoretically to show that the proposed techniques have third- and sixth-order convergence. Per cycle, the novel cubically schemes comprise three evaluations of the function while the sixth-order method includes four function evaluations. The theoretical results are supported by numerical tests to illustrate the accuracy of the contributed methods.
