Learning objectives
Students must demonstrate sufficient knowledge and understanding of the basic results of multivariable calculus and ordinary differential equations. Lectures emphasize concrete computations over more theoretical considerations with little emphasis on exceptional cases.
In particular, students must
1. exhibit sufficient conceptual understanding and good computational fluency in standard cases;
2. be able to exploit tools from multivariable calculus and ordinary differential equations for solving problems ranging from simple to medium difficulty;
3. be able to evaluate coherence and correctness of results obtained by themselves or by others;
4. be able to communicate in a clear and precise way the subjects of lectures using the appropriate scientific lexicon;
5. be able to read scientific and technical books or articles which exploit tools from multivariable calculus and ordinary differential equations.
Prerequisites
Solid knowledge of single-variable calculus and linear algebra.
Course unit content
Calcolo differenziale ed integrale per funzioni di più variabili reali ed equazioni differenziali ordinarie.

Teaching methods
In-person instruction through lectures (4 hours per week) and exercise sessions (2 hours per week).
Assessment methods and criteria
The method of assessment is traditional, i.e. through a written exam and an oral examination. There are no intermediate tests.
The written exam consists of exercises and multiple choice questions. The oral examination is subject to successful completion of the written exam (grade 16/30 or higher). A successful written exam is valid through the examination session (January-February and June-Sptember). The oral examination aims at assessing knowledge and comprehension of the subjects of lectures. The final grade is the average of the grades of the written and oral exams.
Written and oral exams will be in-person.
Other information
The course will be quite fast-paced and it is essential to work steadily throughout the semester. Attendance at classes is strongly recommended.
