# Secant Root Finding Method

Secant Root Finding Method

Steps of the secant root finding method for a cubic polynomial. The secant method for numerical root finding of the functions consists of the steps =-f()(-)/(f()-f()), beginning with the two starting values and . The method can converge to a root or diverge.
