This book is all about practice on your fx calculator and as you progress through it, you are strongly advised to work through the examples on your own calculator. Re-create all the keystrokes yourself to verify the correct answers. You will not gain very much by just looking at the pages in a passive manner. You need active learning through doing. The first chapter in the book are exercise examples for both the fx-991ES and the fx-115ES calculators whereas the second chapter is for the fx-115ES only. The remaining chapters are for both calculators. Although some of the material may not be on your maths syllabus, you will be able to appreciate how your calculator is used for other types of calculations. There are several books on GCSE and A Level Maths published by Cambridge Paperbacks and if you wish to strengthen your working knowledge of maths using your calculator you will find these books extremely useful.

Statistics is an integral part of your A Level maths syllabus and you will be expected to gain a reasonable working knowledge of the subject. No doubt you will have heard the word statistics on many occasions and in this part of your course you will gain a better understanding of what statistics is all about. Statistics deals with numbers, in particular sets of numbers that are normally derived from measurements. However unlike other areas of mathematics, statistics relates to uncertainty. The first chapter is therefore on probability and how it relates to statistics. As you will discover, statistics is about calculating best estimates and determining the confidence in those estimates. You will be introduced to methods for dealing with differentlytypes of data, small data sets or samples taken from much larger data sets.

Being able to solve problems is an acquired skill that comes with practice. This is the first of a four part series which shows you how to use your Casio fx-991ES scientific calculator to solve mathematical problems and to teach you how maths is used in everyday applications. As part of the Cambridge Maths method, this series is intended to supplement your existing maths text books and classroom work.

If you have worked through Statistics Part 1 and Statistics Part 2 from Cambridge Paperbacks you will have gathered by nowthe subject of statistics requires a great deal of personal application in order to gain a good working knowledge of thesubject. Further Statistics builds on the knowledge you have already acquired. You will find that not all the subjects coveredin this book are included in the Statistics strand of your A Level Further Maths. That will depend on the examination boardsyllabus you are following. Many statistical techniques involve a methodology which is acquired with practice. An important part of the learning process is for you to work through each example using your own Casio fx-991ES Plus calculator. The results should be entered into your own note book – this is active learning and it’s only by doing this that you are likely to gain maximum benefit from the Cambridge Maths Method which underpins the whole learning process.

Matrices and Complex Numbers are crucial components of mathematics and a good understanding of how to use them is particularly important. This book, as the others in this series, is meant to work alongside your recommended text books you use in your A Level Mathematics. It acts as a supplement and will show you how the Casio fx-991ES Plus can be used to great effect in problem solving in both matrices and complex numbers. The fx-991ES Plus has features that are specifically designed to perform matrix calculations and complex numbers calculations. This book will show you how to use these features effectively.

When there is a need to perform calculations on arrays of numbers at the same time, then matrices are used. In fact computers processing huge arrays of numbers use matrices. A good working knowledge of matrices is essential for every applied mathematician. In this book you will be introduced to a few basic concepts of matrices and how your fx calculator can be used to perform quite difficult matrix calculations.You will see an alternative way of looking at simultaneous equationsand also rotation of vectors in 2D space. Using your fx-991ES PLUS or fx-115ES PLUS calculator you can actually perform these calculations yourself and not just read about them. A little known fact – your fx calculator has some very powerful features for performing complex number calculations.

This book has been written to enable you to gain a good understanding of trigonometry and how your Casio fx-991ES Plus calculator can be used to further your understanding of the subject. Trigonometry forms an important part of your A Level Maths syllabus and this book should be used alone side your classroom text book on the subject. It will provide you with the skills to perform trigonometry calculations on your fx-991ES Plus calculator. You will already have covered some of the material in this book in your GCSE Key Stages 4, in fact the first few chapters will consulate your existing knowledge.

The second book on statistics in the Cambridge Paper-backs A Level Maths series contains much of the material you will need to continue on building your knowledge of the subject. Much of this book is given over to statistical methods and you will need a good understanding of them to gain a solid working knowledge of the subject. As with the first book, the Casio fx-991ES Plus calculator can play a significant role in furthering your understanding of statistics. You will be introduced to several of the in-built features the calculator has specifically for statistical calculations. You may have noticed by now, the major difference be-tween traditional maths and statistics that is the level of precision, the results of statistical processing are only approximations and not absolute values.

One summer evening, twelve-year-old Jim Thomas is surprised by his mother and sister's account of seeing a mysterious creature in their woods. Is it a bigfoot? Thinking there has to be a reasonable explanation, Jim sets upon discovering the truth. In short time, Jim is faced with a being that supposedly doesn't exist. Before long, his friend is in trouble, and only Jim and his family can save him.
