## Teaching methods

Lectures are held in the classroom, that concern both theoretical and applicative aspects. Moreover, exercises are solved by students with the guidance of the teacher, in such a way that it is possible to verify the degree of comprehension and knowledge of the students.

## Assessment methods and criteria

The examinations consist of a written and an oral session. The students are allowed to the oral sessions only if they pass the written examination. In the written examination 3 or 4 questions are asked. The students should exhibit calculus skills and master of different subjects taught in the course. Marks are given to each question.

The oral examination consists of a discussion about the written examination and of questions to verify the level of comprehension of the theoretical parts of the course.
