General Information

Main field: Technology Depth of study relative to the degree requirements: First cycle, in-depth level of the course cannot be classified
Mandatory for: C2
Language of instruction: The course will be given in Swedish

Aim

The aim of the course is to give a basic introduction to linear algebra. A further aim is to give the student a basic ability to use Python to solve common linear algebra problems.

Particular emphasis is put on the role which linear algebra plays in applications in different areas of technology, in order to give the future engineer a good foundation for further studies in mathematics as well as other subjects. The aim is furthermore to develop the students' ability to solve problems and to assimilate mathematical text.

Learning outcomes

Knowledge and understanding
For a passing grade the student must

• with confidence be able to solve linear systems of equations, with or without computer, and be able to demonstrate an ability to geometrically interpret the solutions of such systems.
• be able to represent, handle and compute with - with and without computer - basic geometrical objects in three dimensions, such as points, vectors, lines and planes.
• be able to show a general knowledge of the matrix concept and of its coupling to the concept of a linear transformation, and be able to carry out elementary matrix operations and to solve matrix equations, with and without computer.
• be able to give an overview of and illustrate mathematical concepts in linear algebra that are used to construct and study mathematical models in applications.
• be able to explain the contents of some central definitions, theorems and proofs.
• be able to account for the method of least squares, and be able to implement it in Python for concrete problems.

Competences and skills
For a passing grade the student must

• be able to demonstrate a good ability to carry out algebraic calculations within in the framework of the course.
• in connection with problem solving, be able to demonstrate an ability to independently choose and use mathematical methods within linear algebra.
• in connection with problem solving, be able to demonstrate an ability to integrate concepts from the different parts of the course.
• be able to demonstrate an ability to explain mathematical reasoning in a structured and logically clear way.
• be able to graphically illustrate sets of points in the plane using a computer, and to adapt curves to these.
