Newton's method, also known as Newton-Raphson's method, is a very famous and widely used method for solving nonlinear algebraic equations.Compared to the other methods we will consider, it is generally the fastest one (usually by far). It does not guarantee that an existing solution will be found, however.

WitrynaIf \(x_0\) is close to \(x_r\), then it can be proven that, in general, the Newton-Raphson method converges to \(x_r\) much faster than the bisection method. However since \(x_r\) is initially unknown, there is no way to know if the initial guess is close enough to the root to get this behavior unless some special information about the function is … Witryna4 lip 2014 · 1. Actually guessing proper initial value is helpful to find the root in less iteration. Improper guess of initial value can increase the number of iteration but surely generate the root (if the root can be found by Newton Raphson Method) after some more iteration. I found an easy way to guess comparatively more suitable initial …
