Webbthe method as a fine British achievement,9 and we shall here follow his account of it. Taking the cubic equation y3-2y-5 = 0, as the example given in De analysi, he started with the approximate solution of 2. Let the exact solution be 2+ p, where p is small, and substitute 2+p into the equation in place of y. This generates a new cubic equation,
