The video tutorial introduces the secant method as an alternative to Newton's method for finding roots of functions. It highlights the drawback of Newton's method, which requires the derivative of the function, and explains how the secant method approximates the derivative using a secant line between two points. The tutorial provides examples using cosine and polynomial functions to demonstrate the secant method. It also discusses the order of convergence for different methods, comparing secant, Newton, and bisection methods. The video concludes by emphasizing the importance of understanding all three methods for different scenarios.
