9.5 The Sine & Cosine Ratios Objective: Today we will use the sine & cosine ratios, we will find the sine & cosine of angle measures in special right triangles, solve real-life problems, and we will use a trigonometric identity. Warm-up: Describe the ERROR in the statement of the tangent ratio. CORRECT the error if possible, otherwise explain why it’s not possible.

9.5 The Sine & Cosine Ratios

Objective: Today we will use the sine & cosine ratios, we will find the sine & cosine of angle measures in special right triangles, solve real-life problems, and we will use a trigonometric identity.

Warm-up: Describe the ERROR in the statement of the tangent ratio. CORRECT the error if possible, otherwise explain why it’s not possible.
