Description

This booklet brings together some of those equations which are almost but not quite on the tip of your tongue when you need them most.
It is an aide-memoire, not a text book. Explanations have been kept to a minimum and if you wish to see proofs then you must look elsewhere. Diagrams aim only to help clarify equations and are not to scale.
By rounding figures up or down many of the equations give acceptable answers with no more than a little mental arithmetic but some involve sines, cosines or tangents and solving these means using tables or a cheap scientific calculator.
