![]() The convergence may not always happen.The secant method rule does not use the derivatives of a function.It evaluates one function at every iteration as compared with Newton’s method which evaluates two.Testing the condition (x i+1−x i), is less than some tolerance limit (epsilon). ![]() ![]() Fixing apriori the total number of iterations (limit).Step 5: Exit Convergence criteria for Secant Method The equation used in the following secant method c programs are as follows. The order of convergence of secant method is superlinear. The rate of convergence of secant method algorithm is 1.618, which is really fast comparatively. The secant algorithm does not ensure convergence. The secant method is a Quasi-Newton method and it is seen to be faster in execution in some scenarios as compared to Newton-Raphson method and the False Position Method well. This method is very similar to the Regula Falsi method. It requires two initial guesses which are the start and end interval points. The secant method algorithm is a root bracketing method and is the most efficient method of finding the root of a function. Secant Method for finding the roots of an equation #includeC++ Program for Secant Method to find the roots.
