| 1 | Contribution of the course to learning outcomes in the Bachelor in Mathematics programme. By the end of this activity, students will have made progress in: - Recognise and understand a basic foundation of mathematics. -- Choose and use the basic tools of calculation to solve mathematical problems. -- Recognise the fundamental concepts of some important current mathematical theories. - Establish the main connections between these theories, analyse them and explain them through the use of examples. - Identify, by use of the abstract and experimental approach specific to the exact sciences, the unifying features of different situations and experiments in mathematics. - Show evidence of abstract thinking and of a critical spirit. -- Argue within the context of the axiomatic method. -- Recognise the key arguments and the structure of a proof. -- Construct and draw up a proof independently. -- Evaluate the rigour of a mathematical or logical argument and identify any possible flaws in it.
Learning outcomes specific to the course. By the end of this activity, students will be able to: - To use finite dimensional vector spaces in order to describe the set of solutions of a system of linear equations. - To use matrix representation of linear applications to understand matrix operations, including determinant of a square matrix. - To use properties of linear applications and the rank theorem in order to construct vector spaces and to evaluate their dimension. - To use euclidian spaces and orthogonal projection in order to solve approximation problems and problems involving distance in R^3 and in some other spaces. - To use technique of diagonalisation of a linear operator in order to study the evolution of a linear system and to determine the character of a quadratic form.
