In theory (see Learner Workload) you are supposed to spend seven hours per week on MATH7021. We have voted for the OFFLINE model: my recommendation is that you watch the lecture material, then spend whatever other time you have for MATH7021 on exercises. It is up to you to decide when you complete learning tasks and timetable yourself. There are four hours of MATH7021 slots on your timetable that you can use if you want.

Week 1


We had one hour of Live Zoom. This should be recorded in “Zoom” on the left there. Updated annotated 

You should watch this hour and 23 minutes of lecture video this week:

Gaussian Elimination I (33 minutes)

Gaussian Elimination II (23 minutes)

Gaussian Elimination III (27 minutes)


How much time you put into homework is up to you: of course the more time you put in the better but we all have competing interests. Please feel free to ask me questions about the exercises. 

It might be the case that you need to see more examples (in Week 2 lectures… probably available by Friday evening) before attempting these. On the other hand, if you can do these already you are in a great position in MATH7021.

  • p.30, Q. 1-11
  • Additional Exercises, p.33, Q. 12-22

Submit work for Canvas feedback by Monday 1 February for video feedback after Tuesday 2 February. Ideally you don’t submit work that you are certain is correct, but instead submit work you need help and feedback with. Submit the images as a single pdf file. To do this, select all the images in a folder, right-click and press print. It will say something like How do you want to print your pictures? Press (Microsoft?) Print to PDF. If possible choose an orientation that has all the images in portrait.

Week 2

We will finish the Gaussian Elimination examples and begin to look at applications of linear systems to traffic and pipe flow.

35%  Assignment 1

I may release Assignment 1 before I know the hand-in date… hopefully there will be some coordination on this quite soon.


Please feel free to ask me questions about the exercises via email. I answer emails every morning seven days a week.
