Analysis of convergence shows the method with sixth-order convergence. Several numerical examples are given to illustrate the efficiency and performance of the proposed method. Comparison of results with other methods has also been given.enmodified Halley's methodcontra-harmonic meanorder of convergencenonlinear equationArticle
