Mathematics II

Knowledge and understanding:

students will learn some basic mathematical concepts and will develop the skills of calculation and manipulation of the most common objects of Mathematical Analysis: among these, integrals for functions of one or several real variables, the differential equations and the differential calculus for real functions of two or several real variables.

Applying knowledge and understanding:

through examples related to applied sciences, the student will be able to appreciate the importance of Mathematical Analysis as an important modeling tool.

Making judgments:

students will be able to deal with some simple but significant methods of Mathematical Analysis with sufficient rigor to refine their logical skills. Many demonstrations will be presented in a schematic and intuitive way to engage students and encourage them to achieve the goal on their own.

Communication skills:

by studying Mathematical Analysis, students will learn to communicate with rigor and clarity both orally and in written form. They will learn that using a correct language is one of the most important means of clearly communicating any scientific topic, not only mathematics.

Learning skills:

students, especially the most willing, will be stimulated to deepen some topics, also through group work.

Lectures complemented by exercises

If the teaching is given in a mixed or remote way, the necessary changes may be introduced with respect to what was previously stated, in order to respect the program envisaged and reported in the syllabus.

Exams may take place online, depending on circumstances.
