NEWTON'S METHOD

This is a way to solve an equation of the form f(x) = 0 when f is a
differentiable function.

A step in Newtonâ€™s method consists in starting at a point on your
curve, moving along the tangent line there to the x-axis, then jumping
back to the curve, You repeat such steps until you reach a point at
which the curve meets the x-axis.

You can enter your function as usual or use one on the menu. The default function illustrates what can happen. When the function has more than one zero, the one you reach depends on where you start.

The top slider and directional circles move the starting point. Those below change the number of such steps shown.
