*We are currently updating this course*, and the new version will be available by the end of summer 2023

## Introduction

This material assumes familiarity with algebra at the non-calculus level, and with elements of two-dimensional geometry. Different topics are summarised in separate sections and worked examples are given to show the application of the material. These are followed by problems which the student should undertake to ensure satisfactory understanding of the section.

Many students may already know much of the material presented, in which case it may only be necessary to make a quick reminder of the terminology used throughout the course. It may also be useful for access to formulae, and several oft-used relationships, differentials and integrals are summarised in an appendix. More advanced mathematical material than appears here may be introduced as needed during the course. Definitions of mathematical terms are printed in bold type.

## 12. Useful Links

The following resources may be useful as further references. They’re presented in order of usefulness.

**Mathcentre student website**

https://www.mathcentre.ac.uk/students.php** ****Leaflets **available on topics e.g. functions, complex numbers, trigonometric functions etc. with non-interactive exercises (answers provided). Some but not all of the materials appear to be the same as the HELM resources.**Booklets **containing more detail with exercises and answers on similar topics such as Cartesian components of vectors and trigonometric functions.**Exercise booklets **on a limited range of topics containing lots of exercises with answers e.g. 29 pages of problems on differentiation should you require them!**Diagnostic tests **on a big range of topics. These use Active X controls which you may need to download. These resources don’t seem to have been used by many students according to their â€˜ratings’ so their quality is unconfirmed.**Short video clips **: an excellent range of clips illustrated by examples worked on stream. You’ll need Windows Media Player 9 or equivalent and sound to get the benefit.**Online DVDs **with detailed coverage of algebra, differentiation, integration and trigonometry.**Search function:** if you can’t find what you want in the above, you can search the site.

**University of Plymouth Maths Support Website**

https://www.plymouth.ac.uk/schools/school-of-engineering-computing-and-mathematics/mathematical-sciences/mathematical-sciences-outreach/mathaid

Some good materials here in .pdf format with interactive exercises and solutions. Topics include vectors and differentiation.

**BBC maths education website**

https://www.bbc.co.uk/teach/skillswise/maths/zfdymfr

Some excellent first principle explanations of e.g. differentiation and integration here. Not an interactive site but maybe a good starting point if you’re really rusty!

**Helping Engineers Learn Mathematics (HELM) website**

https://www.lboro.ac.uk/departments/mlsc/student-resources/helm-workbooks/

Two types of resources might be useful: Workbooks and CAL packages.**Workbooks**: full contents are not available. However, if you click on a topic, sections which are underlined can be accessed as .pdfs. e.g. some aspects of functions, equations and complex numbers.**CAL courseware**: this covers 3 areas: sequences and series, matrix multiplication partial differentiation. To use the courseware you need to download Macromedia Authorware Player which you can get from the site. Some of the work may be too simple and the animations are a little irritating!
