Teaching methods

The course consists of lessons describing the fundamental concepts of real and vector functions of several real variables. Lessons are completed with examples and counterexamples illuminating the theoretical content. Futhermore a lot of exercises are solved in the classroom.

Assessment methods

The assessment consists in a written part, lasting three hours, containing both the resolution of various exercises and theoretical questions (definitions and theorems, possibly with proofs).

The written test is passed if one gets a grade greater  or equal than 18/30.

Students, that have already passed the T1 Mathematical Analysis exam and who pass the written test of Mathematical Analysis T2, have the possibility to face a further theoretical test by registering on a suitable Almaesami list. In any case the obtained result can not be modified more than two points (positively or negatively). Otherwise we proceed to verbalize the result of the written test by tacit assent, a week later from the publication on Almaesami of the results of the written test.

On the other hand, students, passing the aforementioned written part but that do NOT have yet  passed  the T1 Mathematical Analysis exam, must necessarily take a further theoretical test, enrolling on Almaesami in the appropriate lists.

The theoretical part of the exam dwells upon the comprehension of the relevant concepts and on the knowledge of definitions and the statements of fundamental theorems. Proofs of some theorems, clearly detailed, may be required.
