The Secant Method is a root-finding algorithm that uses a succession of roots of secant lines to better approximate a root of a function. Developed independently of Newton's method and predating it by over 3,000 years, the Secant Method is a valuable tool for calculating function roots.

This app, developed by plr, allows users to easily calculate the root of a simple function by showing all the iterations needed. With simple function recognition, users can input functions like "x^3+2x^2+10x-20" and the app will provide the necessary iterations to determine the root. By adding the two previous values and the error percentage, users can track the progress of the algorithm. The iterations are presented in a table format for easy reference.

In future updates, the app will include more complex function recognition, further enhancing its capabilities for solving root-finding problems.
