Diameter (of a circle)
This entry briefly looks at the diameter of a circle. The word “diameter” comes from Greek διάμετρος (diametros), “diameter of a circle”, from δια- (dia-), “across, through” + μέτρον (metron), “measure”. The diameter of...

Algebra and functions notes
Here are a few notes that are useful when working with algebraic expressions and functions. Remember you simplify an expression by collecting like terms You can also simplify expressions by using rules of indices...
Rules and Formulae
This chapter explores rules and formulae. It covers using letters to represent unknown numbers, substituting numbers into simple expressions and formulae and understanding basic fomulae. Fomulae contain letters which represent unknown values. The values...
Formula substitution
This chapter explores substitution in formulae or formulas. The chapter first looks at subsitition in simple equations or formulae then follows on to much harder expressions or formulae. Overall it is a very simple...
Rearranging Equations
In this section we’re going to be looking at rearranging equations. We shall explore how to arrange linear equations, brackets, fractions and quadratics. This entry explores the basic ideas of rearranging equations. You can...
R-Alpha Method
In this article we shall be exploring the R-alpha method. We shall explore how to use expressions such as Rcos(x+α) and Rsin(x-α) in connection with acosx ± bsinx. Furthermore we shall explore how to...
Cosine Rule
In this chapter we shall be exploring the cosine rule. In trigonometry we can use the cosine rule to find the missing sides and angles in a triangle. You must have some basic knowledge...
