Equations, Matrices and Polynomials - Algebra app for iPhone and iPad

This application contains the following tools:

- Equations and Inequalities solver (Second Degree)
- 3x3 and 4x4 matrices Solver
- Product of Polynomials
- Ruffini: Polynomials roots finder

- Equations and Inequalities solver (Second Degree)

It solves the equations and inequalities of the second degree by the graphical method and the numerical method.

Through the analysis of the sign of the coefficient of the variable of the second degree, and the delta, the roots are determined and, in the case of inequality, the range of solutions.

- 3x3 and 4x4 matrices Solver

It calculates the determinant and inverse matrix (with integer coefficients)

- Product of Polynomials

It calculates the product of two polynomials up to the fourth degree (with integer coefficients)

- Ruffini: Polynomials roots finder

It finds the roots of polynomials of third and fourth degree by the method of Ruffini, for polynomials with integer coefficients.

Ruffini method also provides information for the decomposition of a polynomial: the polynomial can be divided according to the root found and the coefficients resulting from the graph.
