## 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.

**Information for students with disabilities and/or DSA.**

As a guarantee of equal opportunities and in compliance with current laws, interested students can ask for a personal interview in order to plan any compensatory and/or dispensatory measures, based on their specific needs and on teaching objectives of the discipline. It is also possible to ask the departmental contacts of CInAP (Center for Active and Participatory Integration - Services for Disabilities and/or DSAs), in the persons of professors Giovanna Tropea Garzia and Anna De Angelis.
