Abstract

The discipline is aimed at first-year students of the direction "International Business and Management/Management". The purpose of the course is to study basic concepts, master the basic methods of linear algebra and their application for the construction of economic and mathematical models. The course examines the theory of matrices and determinants, the structure of solutions of systems of linear algebraic equations, linear spaces, the basic concepts of analytical geometry on the plane and in space, second-order curves. As a result of learning the discipline, the student have to know the basic concepts of linear algebra, methods for solving systems of linear algebraic equations, elements of vector analysis and analytical geometry; be able to apply the apparatus of linear algebra in problems of forming economic models and solving applied problems; have skills in solving systems of linear equations and constructing diagonal quadratic forms, in applying linear algebra methods in other academic disciplines and scientific work.
Learning Objectives

Learning Objectives

  • The goals of learning the discipline "Linear Algebra" are the study of sections of matrix algebra, the solution of systems of linear equations and vector analysis, which allow the student to navigate in such disciplines as" Probability Theory and Mathematical Statistics", "Game Theory and Decision Making". The course "Linear Algebra" will be used in the theory and applications of multidimensional mathematical analysis, differential equations, econometrics. The course materials can be used for the development and application of numerical methods for solving problems from many fields of knowledge, for the construction and research of mathematical models of such problems. The discipline is a model applied apparatus for students of the direction "International Business and Management/Management" to study the mathematical component of their professional education. As learning outcomes the student should: • know the basic concepts of linear algebra, methods for solving systems of linear algebraic equations, elements of vector analysis and analytical geometry; • be able to apply the apparatus of linear algebra in the problems of forming economic models and solving applied problems; • have skills in solving systems of linear equations and constructing diagonal quadratic forms, in applying linear algebra methods in other academic disciplines and scientific work.

Assessment Elements

  • non-blocking Test 1
    The test is carried out in the classroom, in writing, 80 minutes. In the case of a distance learning format, control work is carried out remotely. The student must demonstrate the ability to work with matrices and determinants, be able to find a solution to a system of linear equations using Cramer's formulas, find the inverse matrix (through algebraic additions and the method of elementary transformations), and solve matrix equations, find the basis of the vector system and decompose the vector by the basis.
  • non-blocking Test 2
    The test is carried out in the classroom, in writing, 80 minutes. In the case of a distance learning format, control work is carried out remotely. The student must demonstrate the ability to work with matrices and determinants, be able to find a solution to a system of linear equations using Cramer's formulas, find the inverse matrix (through algebraic additions and the method of elementary transformations), and solve matrix equations, find the basis of the vector system and decompose the vector by the basis.
  • non-blocking Self work
    The teacher of the practical seminars evaluates the independent work of students: the completion of homework and preparation for seminars are evaluated. The control can be carried out in the form of oral and written surveys on the material of homework. The accumulated score on a 10-point scale for independent work is determined before the final control – Оself work
  • non-blocking Exam
    The exam is conducted in a classroom, in writing, 80 minutes. In the case of a distance learning format, the exam is conducted remotely. On the exam, the student must show knowledge of the theoretical part of the course: knowledge of the formulations of theorems, properties, definitions, basic proofs, be able to apply properties and theorems in practice, be able to solve problems.
