The development of Newton’s method by enhancing the starting point

open access: yesInternational Journal of Trends in Mathematics Education Research, 2023
In general, nonlinear problems cannot be solved analytically. A special theory or method is needed to simplify calculations. Many problems that are too complex, an exact solution is needed to support numerical solution.
