Regula falsi

Numerical method used to approximate solutions of univariate equations

In mathematics, the regula falsi, method of false position, or false position method is a family of algorithms used to solve linear equations and smooth nonlinear equations for a single unknown value. In its oldest known examples found in cuneiform and hieroglyphic writings, the method replaces simple trial and error with proportional correction of an initial guess. In modern usage, the method relies on linear interpolation based on two different guesses.
