2 sin 9° cos 9° = sin(2 × 9°) = sin 18° ∵ sin 18° = 0.309 ⇒ 2 × (sin 9° cos 9°) = 0.309 Example 2: Using the value of sin 18°, solve: (1-cos²(18°)). Solution: We know, (1-cos²(18°)) = (sin²(18°)) = 0.0955 ...
⇒ 2 × (sin 22.5° cos 22.5°) = 0.7071 Example 2: Find the value of sin 45° if cosec 45° is 1.4142. Solution: Since, sin 45° = 1/csc 45° ⇒ sin 45° = 1/1.4142 = 0.7071 Example 3: Find the value of 5 sin(45°)/7 cos(45°). ...
