WitrynaIf you start it anywhere near a root of f(x), Newton’s method can converge extremely quickly: asymp-totically, it doubles the number of accurate digits on each step. However, if you start it far from a root, the convergence can be hard to predict, and it may not even converge at all (it can oscillate forever around a local minimum).
