## AIMS AND CONTENT

LEARNING OUTCOMES

The course aims to provide basic technical notions and tools on complex numbers, linear algebra and analytical geometry.

AIMS AND LEARNING OUTCOMES

The student must learn the concept of number of solutions of a mathematical problem, must know how to work with complex numbers, vectors and matrices, including their diagonalization, must be able to solve equations and linear systems, must know how to work with vector spaces and subspaces, must be able to make a change of coordinates in the plane and in space, as well as knowing how to solve simple problems concerning lines, planes, spheres, circles and conic sections.

PREREQUISITES

- Algebra: factor decomposition, equations and inequalities (first, second degree and fractional);
- Trigonometry: definitions of sine, cosine, tangent, their graphical representations and main formulas;
- Euclidean geometry: basic concepts related to lines and circles, and their graphical representations.

Teaching methods

The course has a duration of 12 weeks (4 months in total) and consists of 5 hours a week (3 hours dedicated to theory and 2 hours for exercises).
