Numerical Analysis 2S is a calculator which provide you different numerical methods with some facilities for learning it. These methods allows to solve problems about one-variable equations, systems of equations and interpolation.

The most relevant features of this application are:

- Graph of continuous functions.
- Friendly keyboard with the most important trigonometric, polynomial, exponential and logarithmic functions.
- Finding roots in the functions, see their graphs and tables with their iterations in One Variable Equations Chapter.
- Solution of systems of linear equations nxn (n equations, n variables) through matrices.
- Animations of direct methods to show the process to solve systems of linear equations.
- Get the pivoted matrix in the LU factorization and iterative methods such as Jacobi and Gauss Seidel.
- Handles mathematical expressions in matrices with complex numbers (Cholesky factorization).
- Plotter of interpolating polynomials that allows to graph the polynomial that passes through given points and observe how the function behaves in said points.
- Output of pure mathematical expressions in Interpolation Chapter.
