WitrynaDetails. Newton's method (also known as the Newton-Raphson method or the Newton-Fourier method) is an efficient algorithm for finding approximations to the zeros (or roots) of a real-valued function f (x). The iteration goes on in this way: x k + 1 = x k − F U N ( x k) F U N ′ ( x k) Witryna7 wrz 2024 · Newton’s method makes use of the following idea to approximate the solutions of f ( x) = 0. By sketching a graph of f, we can estimate a root of f ( x) = 0. Let’s call this estimate x 0. We then draw the tangent line to f at x 0. If f ′ ( x 0) ≠ 0, this tangent line intersects the x -axis at some point ( x 1, 0).
