By pro- viding specific requirements for this weighting function, it is shown using Taylor expansion and geometric series that the iterative method have third and fourth or- der of convergence. By choosing specific weighting functions, some known iterative methods are found. Then some numerical simulations are performed to compare the number of iterations of each discussed methodenNewton’s methodnonlinear equationorder of convergenceiterative methodsstudent Paper Post Degree
