## Learning Objectives

To acquire adequate knowledge of the main basics and key mathematical tools necessary for understanding of simple mathematical models and the processing and interpretation of experimental data.

## Course Structure

The lessons will be frontal and participated. Exercises are planned.

If the teaching is given in a mixed or remote way, the necessary changes may be introduced with respect to what was previously stated, in order to respect the program envisaged and reported in the syllabus.
