Jan 12, 2022 · Newtons-method. This program uses Newtons method to find the roots of a function (defined within the source code). As the formula is based on an approximation from a formula, the more iterations you have and the closer your initial guess to the actual guess, the closer the guess to the actual root.

Newton's method, also known as Newton-Raphson's method, is a very famous and widely used method for solving nonlinear algebraic equations.

If \(x_0\) 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 known a priori (e.g., the …
