One of the procedures for solving such an equation is known as the Newton-Raphson Method, developed by British mathematicians Isaac Newton (1642-1727) and Joseph Raphson (1648-1715). It helps to find best approximate solution to the square roots of a real valued function. Newton's Method Equation. This technique of successive approximations of real zeros is called Newton's method, or the Newton-Raphson Method.
