## Test 2

Test 2, worth 15% of your final grade, based on Chapter 3: Algebra, and will take place on Tuesday 3 December in the usual lecture venue of D160.

The sample is to give you an idea of the length of the test. You know from Test 1 the layout (i.e. you write your answers on the paper). You will be allowed use a calculator for all questions.

I strongly advise you that, for those who might have done poorly, or not particularly well, in Test 1, attending tutorials alone will not be sufficient preparation for this test, and you will have to devote extra time outside classes to study aka do exercises.

## Week 9

In Week 9 we finished talking about equations (and quadratic equations) and began studying exponents. We saw at the very end of Friday’s lecture that if we define a function:

$2^{\Box}:\mathbb{R}\rightarrow \mathbb{R}^+$,

by $2^{\Box}(x)=2^x$, then we define $\log_2:\mathbb{R}^+\rightarrow \mathbb{R}$ as an inverse function:

$\log_2:=(2^{\Box})^{-1}$.

## Week 10

We will introduce more and study the properties of uses of logarithms.

If you are a little worried about your maths this semester, perhaps after the Quick Test or in general, I would just like to remind you about the Academic Learning Centre. Most students received slips detailing areas of maths that they should brush up on. The timetable is here.

## CIT Mathematics Exam Papers

These are not always found in your programme selection — most of the time you will have to look here.

## 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.
