SYNOPSIS BRIEF DESCRIPTION This is a basic subject on matrix theory and linear algebra. Emphasis is given to topics that will be useful in economics, including systems of equations, vector spaces, orthogonality, determinants, eigenvalues, definite matrices and quadratic forms.
PRE-REQUISITES None
OBJECTIVES Provide students with a good understanding of the concepts and methods of linear algebra. Help students to develop the ability to solve problems using linear algebra. Connect linear algebra to other fields. Develop abstract and critical reasoning by studying logical proofs and the axiomatic method as applied to linear algebra.
COMPETENCES General: CG1, CG2
Faculty of Economics and Business Transversal: CT1 Specific: CE8, CE9
LEARNING METHODOLOGY A mixed methodology of teaching and learning will be used in all educational activities with the aim of encouraging students to develop a collaborative and cooperative attitude in the pursuit of knowledge.
TOPICS COVERED (Syllabus) The goals are to use matrices and to understand them. Here are key computations and some of the ideas behind them: Solving Ax = b for square systems by elimination (pivots, multipliers, invertibility of A). Complete solution to Ax = b (column space containing b, rank of A, nullspace of A and solutions to Ax = 0). Basis and dimension (bases for the four fundamental subspaces) Least squares solutions (closest line by understanding projections). Properties of determinants (leading to the cofactor formula, applications to inv(A) and linear systems (Cramer)). Eigenvalues and eigenvectors (diagonalizing A, computing powers of A). Symmetric matrices and positive definite matrices (real eigenvalues and orthogonal eigenvectors, tests for x'Ax > 0, applications).
