## Test 1

The 15% Test 1 will take place at 16:00 on 9 October, Week 5, in B263. There is a sample test in the notes.

## Week 4

We did some examples of matrix arithmetic and looked at Matrix Inverses — “dividing” for Matrices. This allowed us to solve matrix equations. Here find a note that answers the question: why do we multiply matrices like we do?

## Week 5

We will look at linear systems, and determinants.

## Study

You should certainly consider putting in some extra study for the Test: in particular BioEng2B who have only one more tutorial before the test. Please feel free to ask me questions about the exercises via email or even better on this webpage.
