21210239 - GENERAL MATHEMATICS

According to the Degree Course in Economics and Business Management (CLEGA), the course aims at enabling students to grasp the basic mathematical topics and tools needed in Economics and Firm Management modeling.
Upon completion of this course, the student will be able to know the basics of mathematical analysis, of differential calculus and of linear algebra;
articulate these notions in a conceptually and formally correct way;
using adequately definitions, theorems and proofs understand the nature of mathematics as an axiomatic-deductive system;
apply the fundamental theoretical results of mathematical analysis, of differential calculus and of linear algebra to the solution of problems and exercises;
actively search for deductive ideas and chains that are fit to prove possible links between the properties of mathematical objects and to solve assigned problems

Modalità Erogazione

In the event of an extension of the health emergency from COVID-19, all the provisions governing the methods of carrying out teaching activities and student evaluation will be implemented. In particular for the course in the academic year 2020-2021 the remote mode will apply It is also advisable to regularly view the institutional information channels prepared by the University for the purpose of timely knowledge of the emergency measures in force.

Modalità Valutazione

The exam will consist of a written test, lasting 50 minutes, which takes place using the Moodle platform, and an optional oral test. The written test consists of solving exercises and identifying the truth or falsity of mathematical propositions and theoretical questions regarding the entire program. The oral exam consists of one or more questions regarding the program covered, including the definitions and proofs of the theorems.
