Secant method is an open root-finding method used in numerical methods. In this video we’ll talk about the Secant Method steps / procedure and talk about the theory of the Secant Method. In Secant we approximate our secant line function using a first-order Taylor Series expansion as this allows for easier derivates.

This video is part of our Numerical Methods course. Numerical methods is about solving math problems through approximating the solution of problems that would be difficult or impossible to solve analytically. In this playlist we will cover topics such as solving systems of linear equations, solving systems of non-linear equations, numerical integration, numerical derivatives, etc..
