ANALISI MATEMATICA II M - Z

The course aims at conveying to the student the knowledge and comprehensions of the mathematical
concepts in the program: sequence and series of functions, limits, derivatives and extrema of functions of
several variables, differential equations and systems, Riemann theory of integration, curves and
differential forms.
In particular, the learning objectives of the course, according to the Dublin descriptors, are:
1. Knowledge and understanding: The student will learn some concepts of Mathematical
Analysis and will develop both computing ability and the capacity of manipulating some
mathematical structures, as limits, derivatives and integrals for real functions of
more real variables.
2. Applying knowledge and understanding: The student will be able to apply the acquired
knowledge in the basic processes of mathematical modeling of classical problems arising from
Engineering.
3. Making judgements: The student will be stimulated to autonomously deepen his/her knowledge
and to carry out exercises on the topics covered by the course. Constructive discussion between
students and constant discussion with the teacher will be strongly recommended so that the
student will be able to critically monitor his/her own learning process.
4. Communication skills: The frequency of the lessons and the reading of the recommended books
will help the student to be familiar with the rigor of the mathematical language. Through constant
interaction with the teacher, the student will learn to communicate the acquired knowledge with
rigor and clarity, both in oral and written form. At the end of the course the student will have
learned that mathematical language is useful for communicating clearly in the scientific field.
5. Learning skills: The student will be guided in the process of perfecting his/her study method.

In particular, through suitable guided exercises, he/she will be able to independently tackle new
topics, recognizing the necessary prerequisites to understand them.

The course consists of blackboard lessons on the theoretical parts and subsequent problem sessions.
Occasionaly, electronic devices might be used.
Should teaching be carried out in mixed mode or remotely, it may be
necessary to introduce changes with respect to previous statements, in line with the program planned
and outlined in the Syllabus.
