MathBin	Secant Method in 2D	Member

The Secant method finds the root (or zero) of a real-valued function using a secant line formed by two points starting with two estimates of the root x₀ and x₁. The root of the secant line becomes the next estimate x₂. This method is a finite-difference approximation of Newton's method, though it predates Newton's method by over 3000 years.
