what is the secant method
Secant Method Another Recursive Method Secant Method The secant method is a recursive method used to find the solution to an equation like Newtonâs Method. The idea for it is to follow the secant line to its x-intercept and use that as an approximation for the root.his is like Newtonâs Method (which follows the tangent line) but it requires two initial guesses for the root. The big advantage of the secant method over Newtonâs Method is that it does not require the given function f(x) to be a differential function or for the algorithm to have to compute a derivative.
