### How to Memorise Mathematical Formulae

A mathematical formula describes a *relationship* using abstract symbols.

Every formula that is worth while has been *derived* from something else … from some real situation, or some abstract analysis of an idea.

Formulae are best learned by *deriving* them and then by *using* them (in context) to solve problems. In these two ways, you will get to see all the parts work together and make sense.
