Learning outcomes

In order to pass the course (grade 3) the student should be able to

solve systems of linear equations using Gaussian elimination and be able to explain the relation between solvability and rank;
use matrix algebra, in particular know how to compute the inverse of a matrix, and know how to compute determinants, and be able to interpret m×n matrices as linear transformations from Rⁿ to R^m;
explain the basic properties of two- and three-dimensional vectors, master elementary vector algebra, decide if vectors are linearly independent, and be familiar with the concepts of basis and coordinates;
give an account of the concepts of scalar product and vector product, know how to compute such products and how to interpret them geometrically;
determine the equations for a line and a plane and how to use these for computing intersections and distances;
define rotations, reflexions and orthogonal projections in two and three dimensions and be able to compute their matrices;
formulate important results and theorems covered by the course;
use the theory, methods and techniques of the course to solve mathematical problems;
present mathematical arguments to others.
