## Recommended Prerequisites

Mathematics (at the secondary level)

## Teaching Methods

The lectures are divided into theoretical and practical. In the theoretical lectures the theoretical exposition is accompanied with practical examples. In the practical classes are solved exercises that illustrate the main concepts.

Students are also encouraged to participate in the classroom, thus stimulating their critical.

In the theoretical lecturers, the concepts are presented using slides and the examples are solved on the board and discussed with the students. In the practical classes, exercises are solved and the participation of the students is encouraged.
