Foreword
The material in this refresher course has been designed to enable you to cope better with your university mathematics programme. When your programme starts you will find that the ability to differentiate and integrate confidently will be invaluable. We think that this is so important that we are making this course available for you to work through either before you come to university, or during the early stages of your programme.
Preliminary work
You are advised to work through the companion booklet An Algebra Refresher before embarking upon this calculus revision course.
How to use this booklet
You are advised to work through each section in this booklet in order. You may need to revise some topics by looking at an AS-level or A-level textbook which contains information about differentiation and integration.
You should attempt a range of questions from each section, and check your answers with those at the back of the booklet. The more questions that you attempt, the more familiar you will become with these vital topics. We have left sufficient space in the booklet so that you can do any necessary working within it. So, treat this as a work-book.
If you get questions wrong you should revise the material and try again until you are getting the majority of questions correct.
If you cannot sort out your difficulties, do not worry about this. Your university will make provision to help you with your problems. This may take the form of special revision lectures, self-study revision material or a drop-in mathematics support centre.
Level
This material has been prepared for students who have completed an A-level course in mathematics
