Basic Mathematics
This section is intended as a reminder for people who have already studied mathematics, but have forgotten what they knew. There are no rigorous mathematical proofs and the explanations are sketchy  so these are just notes, partly to jog my own memory but also to jog yours. If you are a student there are plenty of better maths websites to visit  in order to grasp a particular concept, you may need to study several different sources. If I have said something different from your tutor  your tutor is correct. These articles contain many formulae and may load slowly under Internet Explorer. For some reason Chrome loads them very quickly.
