WebbThe step can be interpreted geometrically as an intersection of the graph’s tangent with the x-axis. Eventually, this may converge to a single root. In interval analysis, we start with an interval x ₀ and utilize the following interval Newton step: x ₁ = (mid ( x ₀) - f (mid ( x ₀)) / f ’ ( x ₀)) ∩ x ₀. Here we use the pivot ...
