![]() ![]() On the other hand, it generally converges faster. Hence, it is obvious that the iteration may not always coverage. In contrast to the Regula-Falsi method, the Secant method does not bracket the root and it is not even necessary to bracket the root to start the iteration. Secant Method Formula Secant Method Formula Thus, if x i -1 and x i are two approximations to the root, then the next approximation x i+1 to root is given by the following equation. Instead, we always retain the last two points to generate the next. The Secant method is similar to the Regula-Falsi method, except for the fact that we drop the condition that f(x) should have opposite signs at the two points used to generate the next approximation. In this tutorial, we will learn how to find out the root of an equation using the secant method in C++.Before proceeding further let’s first understand what is the secant method. ![]() The Secant Method is used to find the roots of an equation. ![]()
