Objectives and competences

Students get familiar with the basic concepts of linear algebra, necessary for further study: basics of two and three-dimensional euclidean geometry, matrix algebra, solving systems of linear equations, calculating with polynomials and basic elements of abstract algebra. They learn a mathematical way of thinking and achieve practical and working knowledge from the field of linear algebra.

Intended learning outcomes

Knowledge and understanding:
Knowledge and understanding of the basic concepts and methods of linear algebra. Application of the achieved knowledge.

Application:
Linear algebra is one of the fundamental subjects in the study of natural, technical, social and almost all other science fields.

Reflection:
Integrating theoretical and practical procedures for solving basic practical problems.

Transferable skills:
Mathematically correct formulation of problems, the choice of appropriate methods, capability of acurate solving of problems and analysis of obtained results.

Learning and teaching methods

Lectures, exercises, homeworks, consultations

Assessment

2 midterm exams instead of written exam, written exam
Oral exam
grading: 5 (fail), 6-10 (pass) (according to the Statute of UL)
