Linear algebra

Math cafe

Please remember that we have a math-cafe where you can get help with your unsolved exercises (provided you have signed up as described here). Next session is:

  • MS Teams: Thursday 25/4 16:15–17:15 on MS Teams.

Math cafe

Do you have a hard time understanding linear algebra and/or calculus at the first study year, and are you determined to do something about it?

Then Math cafe is just the right thing for you. It is held online on selected dates on all three campi. Dates and times are listed below. You must enroll in the team with the code fx86w0k.

It is an extra possibility for getting help with maths. A teaching assistant is available to help you with exercises from the last few lectures.

Always write a minimum of 24 hours in advance if you need help, and also specify which exercises you need help with. It is important to complete this step. The reason being that different study programmes have different exercises, so the teaching assistants cannot be expected to help unless they have had time to prepare.

Consider in advance what you want to ask the teaching assistants and how you are going to pose the question via Teams (do you want to write something on paper, upload in image, or something third).

Use the channel for the relevant date – that is the channel the teaching assistants keep an eye on.

Dates

Currently the allocated dates are (will be updated throughout the semester):

  • Thursday 15/2 16:15–17:15 on MS Teams.

Information for re-examinees

Lectures are streamed and saved as a video. Check Moodle to find links to the individual lectures. Links to the Moodle pages of different blocks are given below.

You are allowed to participate in the exercise sessions, but you are only allowed to sit in the common areas.

Description of blocks

Block 1 (Moodle page)

Vectors, matrices and systems of linear equations. The topics correspond loosely to lectures 1, 2, 3, 4, 5 as well as parts of 6 from the old course.

Block 2 (Moodle page)

Subspaces, bases, eigenvalues and diagonalization. The topics correspond loosely to lectures 6, 7, 8, 9, 10, 13, 14 from the old course.

Block 3 (Moodle page)

(Abstract) vector spaces. The topics correspond loosely to lectures 11, 12 and parts of 13 from the old course.

Block 4 (Moodle page)

Orthonormal bases. The topics correspond loosely to lectures 15, 16 from the old course.

Block 5 (Moodle page)

Linear programming. New part of the curriculum, which has not been covered previously.

Block 6 (Moodle page)

Matrix factorization. New part of the curriculum, which has not been covered previously.

Block 7 (Moodle page)

Orthogonal projections. The topics correspond loosely to lectures 16, 17 from the old course, but with many additions to the curriculum.

Training exercises

Self studies may be found at Pearson's platform. Access can be purchased via Factum Books.

A number of training apps are also available.

TA's during the exam preparation

We offer the help of TA's in your groups during the weeks before the exam. This is organized in MS Teams, where you sign up using the code found on the Moodle page for your course. This is organized in MS Teams where you sign up using the code icvhdv8 (navigate to “All teams” and click “Join or create team” in the top right corner).

The help is available at various times on selected days in January. The help schedule can be found under the tab “Files” at the top of the team.

This help consists of timeslots where you can ask questions within the topics of the course and receive help in solving concrete exercises. The help is primarily focused on the workshops on which the exam is based. The teaching assistants will not necessarily know the details in every single workshop, so we urge you to ask in advance. It is possible that the question cannot be answered immediately, but that you are given some late time.

Within the Team, you can create a new channel by clicking “More”/“Mere” (the three dots next to the Team name) and choosing “Add channel”/“Tilføj kanal”. Each group is asked to create one and only one channel named according to study programme and group number, e.g. “MATØK - B306”. When help is needed, go to the channel “General” and write “Hjælp @MATØK - B306” in the chat. By using “@” MS Teams creates a direct link to the group's channel which the TA can click when she or he is available.

During the period, the number of TA's will vary according to the expected need, so the waiting time may vary significantly. Please prepare well in advance to avoid finding yourselves at the end of a long queue on the final day before the exam.
