Further Mathematics is not that difficult but poses a problem even for those who enjoy maths: you have to study. With AS Maths, once you have confidently mastered a technique, say max/min problems, it is not really necessary to ‘revise’. For A level Maths you must spend a little time memorising trigonometric identities (at least you should) or refreshing your understanding of parametric integration. But in general, provided you practise a lot you will be fine come the exam. For Further Mathematics this process of refreshing is essential.

You will learn more about vectors, transformations and, if you choose to, hyperbolic functions which together provide a foothold on the mountain leading to Einstein’s general theory of relativity. You will also delve more deeply into the theory of complex numbers, culminating with an elegant introduction to complex transformations. Interestingly FP1 and FP2 or FP3 are the only compulsory modules; you have a wealth of choice and can avoid mechanics or statistics (but not both) should one or the other not butter your bread.

Unsurprisingly top universities such as Imperial College demand A* for undergraduate courses in Mathematics or Engineering; surprisingly the London School of Economics (LSE) now asks for it for Economics.

Generally studying Further Maths is a good idea if you like maths but a nightmare if you don’t.

## Why study Further Mathematics?

If you are applying to mathematically related courses at one of the top universities (engineering for example) you are certain to require Further Maths. Such advice is, perhaps, a bit superfluous because if you are considering such courses you MUST enjoy Mathematics. If you do enjoy Maths why not study it in more depth? At the very least it will give you an insight into the difficulties, challenges and beauty of advanced Mathematics.

## Which syllabus do we follow?

We follow Edexcel specification for Further Mathematics.

## How many units are there?

The units in Mathematics are called modules. Students take six modules, two of which are compulsory. The compulsory modules are Further Pure Mathematics: FP1 and either FP2 or FP3. The remaining four optional modules and be chosen from: Mechanics – M1, M2, M3, M4; Statistics – S1, S2, S3; and Decision Mathematics – D1, D2. Students must choose optional modules that they have not previously studied.

## What is each unit about?

### Compulsory modules: Further Pure Mathematics

^{x}= 1 + 2/2! + 3/3! + 4/4! + …. This is the way your calculator does it (almost)). Quite interesting as well are inequalities and advanced differential equations.

### Optional modules

### Mechanics

Principally, M1 is about elementary applications of Newton’s laws (how many?) but, more interestingly, it is about the mathematical model used in analysing the forces of nature. Understanding the model is challenging but, if taken a little further than A level, will give anyone an appreciation of why Aristotle was wrong in thinking that all bodies require a force to keep moving in a straight line (the law of inertia). Equally you should wonder at the genius of Galileo, then Newton, then Einstein in overturning the Greek’s idea. The struggle to understand the model in M1 schools students in the patience necessary to understand Einstein’s Special Theory of Relativity.

1. Practice makes perfect.

2. Proficiency in exams depends on speed; the faster you are the more likely will be the reward of your efforts an A*. Speed depends on pattern recognition; you should be able to identify each and every problem you encounter as a ‘type’ which you have met before. You should rarely have to think in an exam because you have done your thinking beforehand.

M2 also introduces two new topics: centres of mass and conservation of energy. Of course all of these are related to physics. Sadly, much as we would otherwise prefer, most human beings seem genetically wired to silo mentalities: energy in mathematics is somehow different from energy in physics (where there is any energy at all). Still hope springs eternal.

### Statistics

For example, suppose one person in 1000 actually has a particular disease. A pharmaceutical company develops a test which is 100% effective in identifying a disease; ie if you’ve got it, the technique will never fail to indicate that you’ve got it. Unfortunately, if you don’t have the disease, the test is wrong 1% of the time; ie even if you don’t have the disease, the test will say you’ve got it anyway one time in 100. You visit to your doctor’s surgery and test positive: what is the chance that you actually have the disease?

This example, of course, is a question in probability. There is an easy way to solve it and a hard way; and of course we teach you the hard way. The study of probability supplies you with an important way to understand risk. With little more than A level understanding of probability, it will certainly help you understand why Lehman Brothers’ bank collapsed as well as appreciating how careful you must be interpreting the results of trials for a new drug.

S1 also deals with the very important area of correlation and regression. If you have a good teacher (all at Ashbourne!) they will help you understand the true meaning of ‘regression to the mean’ and why correlation is not causation. An example of the latter is (ironically?): the more hours of private tuition students receives the worse their grades (negative correlation). Does this mean that teaching makes students stupid?

Finally S1 examines the analysis of data and will help you answer the following questions: 1. If Bill Gates walks into a pub, what happens to the mean (average) income of the patrons there? What happens to the modal income? Importantly it also deals with the concept of variance or standard deviation, both of which are used by financial boffins to measure risk and volatility in the markets. In fact they will even sell you volatility if you have the appetite!

P.S. You also get to learn quite a bit about bell (normal) distributions which apply to many things like IQs, exam results etc, but regrettably for bankers and the rest of us, not others like the price of shares and derivatives.

This idea leads naturally to the topics of confidence intervals and hypothesis testing which are fundamental for psychologists, economists and doctors.

In S2 Mathematics you will also meet two very important distributions, namely the Poisson and Binomial. These are both extremely useful. For example, the Poisson arose from observing the number of officers in the Prussian cavalry in the nineteenth century who died each year because they were kicked by their horse. If someday you are bored waiting for your bus you might amuse yourself by counting the number of buses (not yours) that arrive at the bus stop each minute. More or less this illustrates a Poisson distribution.

Finally you will apply your knowledge of calculus to continuous distributions.

This module is not dense but is conceptually quite challenging. I suppose it indicates a general principle: in applied maths once you establish a rock solid understanding of the fundamental first principles you should have little difficulty afterwards.
