Theme 9 comprises five core concepts: exploring linear equations and inequalities; exploring non-linear sequences; exploring quadratic equations; inequalities and graphs; sequences, functions and graphs; exploring trigonometric functions

The links immediately below take you to pages dedicated to each core concept.
-
9.1 Exploring linear equations and inequalities
Core concept 9.1 uses both graphical and algebraic representations to deepen students’ understanding of linear functions, including inequalities and simultaneous equations
-
9.2 Exploring non-linear sequences
Core concept 9.2 extends students’ understanding of sequences to look more deeply at non-linear sequences
-
9.3 Exploring quadratic equations, inequalities and graphs
Core concept 9.3 extends students’ understanding of graphs, to include quadratic equations and inequalities
-
9.4 Sequences, functions and graphs
Core concept 9.4 explores what it means to think and reason functionally, with an emphasis on graphical representations, exponential relationships, and transformations of functions
-
9.5 Exploring trigonometric functions
Core concept 9.5 builds on students’ existing knowledge to explore trigonometric functions in depth
