## Test 1

Firstly, some good news. I am going at a different pace to last year so in fact we have covered everything we need to do for Test 1 already. All of Chapter 1 and Sections 2.1, 2.2 and 2.3 of Chapter 2 are all that will be examinable in Test 1. This means that Section 2.4 Continuity on Closed Intervals and Chapter 4 Differentiability are not examinable.

Please find the Sample, Test 1 A and Test 1 B (second two with solutions).

Question 1 will be taken from the exercise sheets, Question 2 from a past exam paper, and Question 3 will be on definitions. Q.1 is worth 4/12.5 or 32%, Q. 2 is worth 5/12.5 or 40% and Q. 3 is worth 3.5/12.5 or 28% (1 correct = 1 mark, 2 correct = 2 marks, 3 correct = 3 marks + 0.5 mark bonus).

For Q. 3 of the test, you need to know the following definitions: *even, odd, increasing, decreasing, quadratic, roots, polynomial, rational function, absolute value, limit, one-sided limit, continuous at a point, continuous, composition. *Q.3 is a harder question and the thinking behind this is that you can get 72% a bare first if you get all of Q.1 and Q.2 — but you will have to be even better than this to get a higher mark.

## Next Week

Therefore we are going to have a period of revision before Test 1. This Monday we will start with Chapter 4, on Wednesday I will go through the sample test and we will have an additional tutorial instead of a lecture on Monday 24.

## This Week

In lectures, we covered from (but not including) Proposition 2.1.5 to (and including) Definition 3.1.1.

## Supplementary Notes

The proof of Proposition 2.3.6.
