Newton raphson method multiple roots

WitrynaAlthough the description of the Newton-Raphson method has been given for functions with a single root, the method can be applied perfectly well to functions with multiple roots. The root on which the method converges is of course determined by the starting value, x 0.As with the interval methods, it is sensible to have a rough idea of the … 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).
