Linear Algebra 2017/2018

  • 6 ECTS
  • Taught in Portuguese
  • Both continuous and final Assessment

Objectives

It is intended that the student is able to:
(i) operate with matrices (addition, multiplication and multiplication by a scalar);
(ii) define, calculate and use properties of the inverse and transpose of a matrix;
(iii) calculate determinants, using their properties and applications;
(iv) discuss and solve systems of linear equations (Gauss-Jordan elimination and Cramer Rule);
(v) define space and linear subspace;
(vi) identify the relationships between elements of a space / linear subspace: dependency / linear independence, generators and bases systems;
(vii) define and determine eigenvalues and vectors of a matrix;
(viii) operate with vectores and matrices with R software.

Recommended Prerequisites

Knowledge acquired in Mathematics of Elementary and Secondary Education.

Teaching Metodology

In practical classes are presented the basic concepts accompanied by the resolution of exercises and study of practical applications. Whenever possible will be done some demonstrations using the software R. Expository, demonstrative and interrogative to introduce the basics methods are used.
They are provided handouts and leaves practical exercises for all the contents.

Demonstration of the syllabus coherence with the curricular unit's objectives

The selected program content, meet consistently the learning objectives. For the purposes of (i) and (ii) the UC contributes directly point 1 of the program. The contents of 1, 2.3 and 4 contribute to create basic skills matrix calculation allowing achieve the objectives (i) to (iv). For the purposes set out in (v) and (vi) contributes directly point 5 of the program and for the purpose of (vii) point 4. The syllabus 4 and 5 are the basis the algebraic calculation reinforced by matrix calculation introduced in points 1, 2 and 3.
The contents of this unit allow the development of a reasoned logical reasoning scientifically and the acquisition of scientific knowledge of algebraic nature for use in the field to develop other courses.

Demonstration of the teaching methodologies coherence with the curricular unit's objectives

The union between the theoretical exposition of the matter (expository method, demo, trial and interrogative), the participation of students, the presentation of examples and solving practical problems on the treated materials (guided practice and debate) enables students to familiarize themselves with concepts and mathematical methods that are the foundation of algebra and matrix calculus, thus being able to achieve the objectives of the course. The use of the R software will give students the opportunity to explore computationally some contents of this course.
