** BLM 1.1: Big Ideas – Trigonometric Functions **


 * T1** Trigonometric functions can help you to describe and analyze periodic relationships and change using words and symbols.
 * T2** When a relationship appears to be periodic in nature, then it is appropriate to consider a trigonometric function to model the relationship.
 * T3** A trigonometric function can be represented in multiple ways (numerically, graphically, geometrically and algebraically) and each representation highlights different characteristics or behaviours, and can serve different purposes.
 * T4** Limited information about a periodic relationship can sometimes, but not always, reveal other information about that relationship.
