## 40% Test 3 – Functions Algebra

This test will takes place Thursday 15 December at 4 pm in Room IT2. More information on Canvas. The ten-week semester has left us very short on preparation for Test 3. Therefore there will be three additional classes in Week 11

• Tuesday 13 December, 14:00, B217 (usual lecture time and venue),
• Wednesday 14 December, 10:00, F1.4 (room change),
• Thursday 15 December, 09:00, F1.4 (room change).

Your preparation for the test is doing exercises (and dipping into the notes when you don’t understand what e.g. one-to-one means). There is an awful lot of exercises in Chapter 3 to 5. Here I pick out some that you could focus on (note Functions summary p.120):

• Sample Test 3, p. 196
• p. 94, Q. 1,3,5
• p. 97, Q. 1-2
• p.105, Q. 1-5
• p.114, Q.1-4, 9-11, 13
• p.141, Q. 2
• p.145, Q. 1-3, Q. 1, 3-4, 8-10
• p.155, Q. 6-9
• p.175, Q. 2-5, 8-10
• p. 189, Q. 1(a), 3, 17-19

This is what I will be recommending students work on in tutorials. If you want feedback on study but cannot make it to the additional classes, please check your work against answers in the back of the manual, and/or email me your work with any questions.

## Mathematics Exam Advice

• You don’t have to answer questions in order Q. 1, Q. 2, etc. If you know in advance the structure of the exam, you can decide in advance what questions you are doing first, second, etc. This is related to:
• Read questions carefully. Don’t glance at a question and go off writing: take a moment to understand what you have been asked to do.
• Don’t use tippex; instead draw a simple line(s) through work that you think is incorrect.

If you do have time at the end of the exam, go through each of your answers and ask yourself:

1. have I answered the question that was asked?
2. does my answer make sense? If no, write that on your script, and then try and fix your solution.
3. check your answer (e.g. if you are looking at something general, look at a special case; substitute your solution into equations; check your answer against a rough estimate; or what a picture is telling you; etc.). If your answer is wrong, write that on your script, and then try and fix your solution.

## Week 10

There was a bit of a turbo-charge to finish the material for the exam. Initially we looked at some properties and computer science applications of logs. Then we looked at algorithmic complexity. It is OK that we skipped some sections — we are on a tight schedule of ten weeks, and everything that was essential was covered, and covered for the final test.

In tutorial, students looked at Sample Test 3.
