Lesson 9.1 Right Triangle Trigonometry (Day 1) Learning Goal: (G-SRT.C.8 - Pre-requisite Skill) I can evaluate trigonometric functions of acute angles. I can find unknown side lengths and angle measures of right triangles. Essential Question: How can you find a trigonometric function of an acute angle θ? Homework Discussion 5 in 5 mi 8.6 km 14.1 mi 2 yd 6. km 7. m 8. yd 9. yes 10. yes 11. 12. 13. 14. no no yes yes The Six Trigonometric Functions Who remembers SOH CAH TOA ? sin θ = csc θ = cos θ = sec θ = tan θ = cot θ = θ opposite side adjacent side hypotenuse Evaluating Trigonometric Functions Evaluate the six trigonometric functions of the angle θ. Ex 1: Ex 2: 25 7 θ Example 3: In a right triangle, θ is an acute angle and sin θ = trigonometric functions of θ. . Evaluate the other five Example 4: In a right triangle, θ is an acute angle and cos θ = trigonometric functions of θ. . Evaluate the other five Group Consensus Evaluate the six trigonometric functions of the angle θ. 1. 3. 4. In a right triangle, θ is an acute angle and cos θ = other five trigonometric functions of θ. . Evaluate the 2. Exit Question: What does the standard deviation tell us about a data distribution?
