Newton root finding method

Witryna17 paź 2024 · Like many other root-finding methods, Newton’s method, also known as Newton Raphson method, is a mathematical technique to find the best possible vales (roots) of a real-valued function. For many simpler equations (e.g. linear, quadratic), there already exists set of formulas to calculate the exact roots of an equation. But in … WitrynaIn numerical analysis, the secant method is a root-finding algorithm that uses a succession of roots of secant lines to better approximate a root of a function f.The secant method can be thought of as a finite-difference approximation of Newton's method.However, the secant method predates Newton's method by over 3000 years.

Although all root-finding algorithms proceed by iteration, an iterative root-finding method generally uses a specific type of iteration, consisting of defining an auxiliary function, which is applied to the last computed approximations of a root for getting a new approximation. The iteration stops when a fixed point (up to the desired precision) of the auxiliary function is reached, that is when the new computed value is sufficiently close to the preceding ones.
