Enter your function, initial guesses, and tolerance into the calculator to determine the root using the secant method.

Secant Method Calculation Formula

The secant method is used to find the root of a function by iterating a sequence of estimates. The following formula is used in the secant method:

xn+1 = xn - f(xn) * (xn - xn-1) / (f(xn) - f(xn-1) )
