WebNewton's Method is a technique for approximating a root to an equation of the form f ( x) = 0. What is required is an initial estimate for the root, called x 1, and an iterative formula: x n + 1 = x n − f ( x n) f ′ ( x n) This produces a sequence x 1, x 2, x 3, … which converges to the root (hopefully).
