Newton method root finding

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. In numerical analysis, Newton's method, also known as the Newton–Raphson method, named after Isaac Newton and Joseph Raphson, is a root-finding algorithm which produces successively better approximations to the roots (or zeroes) of a real-valued function. The most basic version starts with a single-variable … Zobacz więcej The idea is to start with an initial guess, then to approximate the function by its tangent line, and finally to compute the x-intercept of this tangent line. This x-intercept will typically be a better approximation … Zobacz więcej Newton's method is a powerful technique—in general the convergence is quadratic: as the method converges on the root, the difference between the root and the approximation is squared (the number of accurate digits roughly doubles) at each step. However, … Zobacz więcej Newton's method is only guaranteed to converge if certain conditions are satisfied. If the assumptions made in the proof of quadratic … Zobacz więcej Minimization and maximization problems Newton's method can be used to find a minimum or maximum of a function f(x).
