Objectives

This course unit aims the promotion of logical reasoning, methods of analysis and the theoretical development of mathematical concepts is fundamental to support the study of the majority of course units along this programme of studies.

This course unit aims to introduce the basic fundamental concepts of Linear Algebra, Vector Algebra and Analytic Geometry.

At the end of this, students should be capable of:

a) Knowing vector algebraic operations, their properties and how to apply them;

b) Define vector space, vector subspace and Euclidian subspace;

c) Define linear combination of vectors, linear independence and subspace spanned by a set of vectors;

d) Define a basis and dimension of vector space; obtain the coordinates of a vector with respect to a given basis;

e) Define line and plane, properties and represent lines and planes;

f) Solve problems with lines and planes, such as distances, angles and relative positions;

g) Knowing basic matrix operations, properties and operations;

h) Define and calculate the rank of a matrix;

Eligibility for exams

Admission to exam:

a) Attend to Article 7 of the General Evaluation Rules of FEUP;

b) Attend to at least one of the two tests with minimal classification of 6 out of 20.

Calculation formula of final grade

The student must attend to two written exams, with the duration of 2 hours each. Each exam comprises two different parts: a theoretical part, which worth 20% of the final mark and a theoretical-practical part which worth 80% of the final mark. Final mark will be based on the average grade of the two exams.

Exams are scheduled for these dates: 1st written exam: 18 November 2013; 2nd written exam: 16 January 2014.

According to Article 4 of General Evaluation Rules of FEUP, a student in order to pass the course must earn a grade of six out of twenty or better in each of the exams.

At the end of the semester students will be able to attend a new exam in order to improve their final grade. This exam may either only test a part of the program, or the whole program. Only students who got admission to exam can attend this exam.

Date of the exam: 30 January 2014.

Examinations or Special Assignments

Not applicable.

Special assessment (TE, DA, ...)

According to items 1b), 1c), 2 to 4 in Article 9 of General Evaluation Rules of FEUP.

Classification improvement

Classification improvement will exclusively be the result of the written exam according to Article 10 of General Evaluation Rules of FEUP.
