Practice
5
The sine & cosine ratios
6
What are the other trigonometric ratios?
Is there an easier way to remember all the ratios? SOH CAH TOA
7
Example What do you notice? sin S = cos R and sin R = cos S
This is true because the side opposite ∠S is adjacent to ∠R and the side opposite ∠R is adjacent to ∠S
8
The Sine and Cosine of Complementary Angles
How do we write sin 56° in terms of cosine? We can use the sine and cosine ratios to find unknown measures in right triangles
