Title: Lecture 7: Roots of continuous non-linear functions
Course: Numerical Analysis > Section: Module 4: Roots of Non Linear Functions

The root of a real valued function  is the value of the input  that makes . There are analytic methods of determining roots of many types of functions. Yet it occurs in some cases that the analytic method does not exist, we do not know it or is very involving. In such instances there is an alternative approach, the numerical one. In this lecture, we describe three numerical methods of approximating roots of continuous functions: the Bisection and Regula Falsi and the secant methods. We deliberate their merits and weaknesses.
