For this version (15), the option
to calculate the rank of a matrix

For this version (12), the option
to calculate the roots of a polynomial using the method
Newton-Raphson, which allows real roots to be calculated.

In version (3.0), a numeric calculator was added to evaluate expressions like 1/2 * 3 ^ 2-8 * 6 for example.

In version (6.0) two options were added to the menu.
The first is to inform
the coordinates of a triangle and draw the inscribed circle.
This option prints: the incenter, the length of the sides,
the area of ​​the triangle, the radius and the 4 bisectors

The second is to inform
the coordinates of a triangle and draw the circumscribed circle.
This option prints: the circumcenter, the radius, the slopes of the intersecting lines and the interior angles of the triangle

The program is also used to perform the following operations on arrays:

Determinant, Adjoint and Inverse of a matrix,

The option to calculate the determinant of a matrix of order 2 to 10 was added, using the Gaussian method. This method is faster than the traditional system called "row development",

Solution of a system of linear equations (using Gaussian reduction),

Matrix multiplication,

Geometry of a 2 X 2 Matrix,

Staggering a matrix to reduce the system and

Calculation of the roots of a polynomial of degree 2 -> 6.
If it is degree 2, the quadratic equation is used.
If it is greater than 2, the synthetic division is used.
