Roots Finding - Secant method

"The secant method is a numerical algorithm used to find the root of a function. A root of a function is a value of x that satisfies the equation f(x) = 0. In other words, it is a value of x that makes the function f(x) equal to zero.

In numerical analysis, the secant method is a root-finding algorithm that uses a sequence of roots of secant lines to approximate the root of a function f(x). It is also known as the 2-point method because it requires at least two values of approximation to obtain a more accurate result. The secant method is faster at converging on the root of a function compared to the bisection method.

In this video, we will use Microsoft Excel to perform the secant method for root-finding. We will define a function f(x) whose root we want to find, provide two initial approximations to the root, and use a loop and the secant method formula to iteratively improve the approximations and converge on the root of the function."
