21010186 - FUNDAMENTALS OF MATHEMATICS 2

To provide the algebraic and analytical tools that enable the treatment of three-dimensional space, and beyond. In particular, to introduce differential and integral calculus in several variables and linear algebra in its relationship with geometrical thinking. From forms to formulas, and vice versa: introduction to inverse problems and parametrical thinking.

Modalità Erogazione

The course is organized in lectures and exercise class, sometimes using a computer. During exercise classes we give some exercises and problems, let the students try to solve them then we discuss the solution and, if necessary, we give the full solution at the blackboard. In some of the exercise classes the students are requested to use a computer for curves and surfaces visualization.

Modalità Frequenza

Attendance at the course is mandatory for its 75% .

Modalità Valutazione

The student assessment involves a written and an oral exam. Some tests during the course are also planned. The written exam consists of some questions to assess students’ understanding of concepts and their autonomous application.
