## Week 4

In Week 4 we finished Chapter 1 by looking more at relations and their properties. We started our study of Chapter 2: Functions. A function is a special type of relation.

## Week 5

In Week 5 we will continue our study of functions and their properties.

## Test 1

Test 1, worth 15% of your final grade, will take place in the usual D160 lecture venue at 10:00 on Tuesday 16 October. I will email a sample paper in the next week. The names of Laws of Sets on the sample is the same as how they will be named on the final exam.

Test 1 will cover the contents of Chapter 1 and the sample will give an idea of the layout and length of the test. The following *types* of questions are examinable:

- P.20, Q. 1, 3 [note is a typo: it should be ], 4, 6-7, 9, 13-14
- P.26, Q. 1-4
- P.30, Q. 2
- P. 36, Q.1-3

Questions like those exercises not listed here will not appear on your exam paper but are still useful to help your learning and understanding. For example, working with truth tables should help your understanding of the Laws of Sets.

I have also sent on some additional exercises on equivalence relations via email.

## Study

Please feel free to ask me questions about the exercises via email or even better on this webpage — especially those of us who struggled in the test.
