Functions and Graphs and Trigonometry and Modelling
infoWhy this? A fuller study of functions develops ideas of domain, range, composition, inverse and graphical behaviour as connected concepts. This is applied to trigonometric functions can model repeated patterns such as waves, rotations and seasonal change.
scheduleWhy now? Once algebra and calculus are reactivated, students can treat functions as complete mathematical objects rather than isolated formulas. Applying the formal graph work to trigonometric functions to allow students to use amplitude, period and phase with confidence in applied contexts.
