## Unit 1

#### Combinatorics, vectors in the plane and geometry

This unit extends student’s knowledge in the domains of Euclidean geometry, probability and two dimensional vectors.

## UnitÂ 2

#### Trigonometry, matrices and complex numbers

Unit 2 provides an alternative approach to working in two dimensional spaces through matrix operations. Number concepts are extended via the concept and use of complex numbers. These topics and future units will make use of trigonometric theory also introduced in this unit.
