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, …
