⇒ 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 ⇒ (1-cos²(18°)) = 0.0955 Example 3: Find the value of sin 18° if cosec 18° is 3.2360...
The value of cos 3 degrees can be calculated by constructing anangleof 3° with thex-axis, and then finding the coordinates of the corresponding point (0.9986, 0.0523) on theunit circle. The value of cos 3° is equal to the x-coordinate (0.9986). ∴ cos 3° = 0.9986. What is the ...
