## OVERVIEW

The course provides basic knowledge in linear algebra and geometry of euclidean plane and space. The concept of a vector space is introduced first by means of examples, and then formalized. The course ends by introducing the notion of linear map and studying the problem of diagonalization.

## AIMS AND CONTENT

LEARNING OUTCOMES

The course provides the basic knowledge of linear algebra and geometry needed for applications, with special emphasis on vector calculus and linear transformations

TEACHING METHODS

The course includes lectures at the blackboard in which the topics of the program are presented. Examples and exercises designed to clarify and illustrate the concepts of the theory are also carried out.

## EXAMS

EXAM DESCRIPTION

The exam consists of a written and an oral examination. The student can access the oral exam after he passes the written part.

ASSESSMENT METHODS

The written examination tests the ability in solving problems in linear algebra and geometry. The oral part certifies that the student has filled the gaps revealed by the written test and that he is able to express properly the results of the theory.
