Trigonometric-Exact Values
Sine θ, Cosine θ and Tan θ

By the end of this unit, students will be able to:

1. recall and use the exact values of sin⁡θ, $\cos \theta$, and tan⁡θ for θ= 0∘, 30∘, 45∘, 60∘, and 90∘;
2. solve problems involving trigonometric functions using these exact values;
3. apply their knowledge to real-world scenarios and geometric problems.
