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...
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...
