WebbWe introduce the key idea with an example in The idea of Newton’s method. Using general notation, if we have a root approximation xk, we can construct a linear model of f(x) using the classic formula for the tangent line of a differentiable function, (81)q(x) = f(xk) + f ′ (xk)(x − xk). Finding the root of q(x) = 0 is trivial. WebbNewton’s Method: the Gold Standard Newton’s method is an algorithm for solving nonlinear equations. Given g : Rn!Rn, nd x 2Rn for which g(x) = 0.

Webb20 dec. 2024 · Newton's Method is built around tangent lines. The main idea is that if x is sufficiently close to a root of f(x), then the tangent line to the graph at (x, f(x)) will cross the x -axis at a point closer to the root than x.
