Jon's Big Beautiful Book of Maths Formulas

This is a comprehensive collection of the bewildering array of maths formulae and maths jargon that are commonly encountered in high school maths, and a little beyond. It covers quadratic equations, exponentials, logs, areas, volumes, trigonometry, calculus, series, vectors and interest, among other things. There are glossaries and lists of notation, too. It is aimed at those who are less confident in maths and those who just need a quick reference.
