Students learn how to solve trigonometrical equations using special triangles.
As learning progresses they use the properties of trigonometric graphs to find additional solutions beyond 90°.
Differentiated Learning Objectives
- All students should be able to calculate the exact values of Sin and Cos 30°, 45°, 60° and 90°.
- Most students should be able to solve trigonometric equations such as 2Cos45°.
- Some students should be able to use trigonometric graphs to find alternative solutions to Sin, Cos and Tan 30°, 45°, 60° and 90°
