## OVERVIEW

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

## AIMS AND CONTENT

### 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 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

### AIMS AND LEARNING OUTCOMES

Real / complex coefficient polynomials: factor breakdown, fundamental theorem of Algebra and Ruffini's theorem.

Geometric vectors: equivalence, module, versorem operations and properties. Scalar and vottorial product and property. Mixed product of carriers.

Linear systems: elementary operations on equations and Gauss theorem-algorithm

Matrices: various definitions, operations and properties. Reverse matrix. Definition of characteristic and Rouchè Capelli Theorem with method for determining the solutions of a linear system. Determinant definitions e

Finitely generated vector spaces: basic definitions of size and relative theorems, subspaces.

Definition of linear application.

Changes of coordinates in the plane and in space, formulas of rotations and translations. Orthogonal matrices.

Matrix diagonalization: definition of eigenvalue, eigenvector and relative theorems. Spectral theorem for symmetric matrices.

Lines in the plane and lines and planes in space: parametric and Cartesian equations. Various formulas of analytic geometry.

Spheres and circumferences in space.

Quadratic forms and Conic sectionss: associated matrices and defining character.
