• from Feb 19, 2024 to Jun 06, 2024

## Learning outcomes

At the end of the course the student knows the basic definitions, their relationship and the main properties of the following topics: -numercal series - curves, surfaces and vector fields, integration of functions and of vector fields -real functions of more than 1 real variables (in particular of 2 real variables): continuity, differentiability, critical points, integration. The student is able to solve suitable exercises on these topics.

## Teaching methods

The course consists of lessons (respecting the anti-covid rules) describing the fundamental concepts of functions of two or more real variables and differential equations. Lessons are completed with examples and counterexamples illuminating the theoretical content. Futhermore many exercises are solved in the classroom.

## Assessment methods

The examination consists of a preliminary written test (exercises) and a test about the theoretical part.
The preliminary written test (exercises) lasts two hours and 30' and consists in solving five exercises related to the topics of the course. In order to sustain it the student must register at the test through AlmaEsami [https://almaesami.unibo.it/] . If this written test is passed (at least 15/30), the student can sit for the test concerning the theoretical aspects of the course. The student must show to know the concepts explained during the course (in particular definitions and theorems) and how to connect them. The theoretical part of the exam must be passed in the same "sessione" of the preliminary written test (exercises): in the same "appello" or in the subsequent one.
