Teaching methods

The teaching is based on lectures supplemented by exercise activities in the classroom. A teaching support after hours of lessons, based on exercises and mainly aimed at preparing for the written test, is proposed

Assessment methods

The exam consists of a written test and an oral test. The written exam is a multiple choice test of numerical exercises and theory questions. The interview focuses on theoretical arguments of the program and is designed to test the level of knowledge and understanding of the topics of the program, the ability to use mathematical language and to apply correctly the hypothetical deductive method.

Learning outcomes

Through lectures and individual study, knowledge and understanding of: elementary algebraic structures, vector spaces, matrices and their properties, linear applications and their properties, algorithms for solving linear systems, conditions of diagonalizability of a matrix, scalar and vector product, Euclidean spaces and the notions of parallelism, orthogonality and Euclidean distance between subspaces (with particular reference to the Euclidean plane and the Euclidean space of dimension three).
Through classroom exercises, the support activities and individual work, ability to:
determine basis and dimension of a vector space,
determine kernel and image of a linear transformation, checking injectivity and / or surjectivity
and represent a transformation by a matrix,
calculate the determinant and the rank of a matrix,
discuss and solve linear systems,
calculate the eigenvalues and discuss diagonalizability of a matrix,
construct orthonormal bases in a Euclidean vector space,
determine the orthogonal complement of a Euclidean subspace,
represent by cartesian and parametric equations Euclidean subspaces,
determine the relative position between Euclidean subspaces and calculate the distance,
calculate areas and volumes in the Euclidean space,
solve simple problems of Euclidean geometry.

Attitude towards a methodological approach that leads to verify the claims through rigorous arguments and methods presented.
Ability to self-assessment of their skills and abilities.

Ability to deal with accurately and coherent a dialectic, arguing with precision

Acquisition of mathematical knowledge as its assets, that can use at any time of the cultural path
Attitude towards a methodological approach that leads to an improvement in the method of study and in the learning ability.
