WebJul 3, 2016 · Explanation: tan(11 π 12) = tan(π − π 12) = −tan( π 12) = − tanθ, say where, θ = π 12, so that 2θ = π 6. Now recall the identity :tan2θ = 2tanθ 1 − tan2θ ∴ tan( π 6) = 2t 1 −t2, where, t = tanθ = tan( π 12) ∴ 1 √3 = 2t 1 − t2 ⇒ 1 − t2 = 2√3 ⋅ t ⇒ t2 +2√3 ⋅ t = 1 ⇒ t2 + 2√3 ⋅ t + (√3)2 = 1 +(√3)2 ∴ (t +√3)2 = 22 ∴ t + √3 = ± 2 ∴ t = ± 2 − √3 WebApr 10, 2024 · Use the given information to find the exact value of a. sin 2 theta, b. cos 2 theta. and c. tan 2 theta. cos theta = 16/34, theta lies in quadrant IV sin 2 theta = (Type an integer or a fraction. ...
