WebNewton's method is a method for approximating the value of the roots of a function that cannot be solved for algebraically. Given the function f (x) and an estimate value for the root x 0, the first approximation is. The second is. and in general. The more times this process is repeated, the better the approximation will be. WebIt is well known that a damped or underrelaxed Newton’s method will sometimes solve a system of nonlinear equations when the full Newton’s method cannot. This happens, for example, when only a poor initial approximation to the solution is known. By considering Newton’s method as Euler’s method applied to the corresponding differential equation, … citibooks israel
