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 f. The secant method can be thought of as a finite difference approximation of Newton's method. However, the method was developed independently of Newton's method, and predated the latter by over 3,000 years.

This app can show you all the iterations needed to calculate the root of a simple function.

Features:
- Simple function recognition (i.e. x^3+2x^2+10x-20)
- You must add the two previous values and the error percentage.
- All the iterations are shown as a table.

Coming up:
- More complex function recognition will be added.
