WebSolution Let us assume θ = 22. 5 0 So, 2 θ is 45 0. We know that the identity is sin 2 θ = 1 - cos 2 θ 2 - - - - - 1 On substituting the value of θ in equation 1, we get sin 2 22. 5 0 = 1 - cos 2 × 22. 5 0 2 = 1 - cos 45 ° 2 = 1 - 1 2 2 = 2 - 1 2 2 = 0. 146 [ 2 = 1. 414] So, sin 22. 5 0 = 0. 146 = 0. 38 Hence, the value of sin 22. 5 0 is 0. 38 . WebUsing the tan 2a formula, 2 tan 22.5°/ (1 - tan² (22.5°)) = tan (2 × 22.5°) = tan 45° ∵ tan 45° = 1 ⇒ 2 tan 22.5°/ (1 - tan² (22.5°)) = 1 Example 3: Using the value of tan 45°, solve: (sec² (45°) - 1). Solution: We know, (sec² (45°) - 1) = (tan² (45°)) = 1 ⇒ (sec² (45°) - 1) = 1 FAQs on Tan 45 Degrees What is Tan 45 Degrees?
