WebMar 25, 2024 · Explanation: Using the identities: 1 + tan2θ = sec2θ. 1 secθ = cosθ. tanθ = sinθ cosθ. sin2θ = 1 −cos2θ. 2cos2θ − 1 = cos2θ. Start: 1 − tan2θ 1 + tan2θ =. WebAnswer (1 of 4): First let’s just look at the interval from zero to 360 for 2θ: tan² 2θ = 3 so tan 2θ = ±√3. From the Unit Circle we get the following: 2θ = π/3, 2π/3, 4π/3, 5π/3. Now divide by 2 to get θ. θ = π/6, π/3, 2π/3, 5π/6 or in degrees: θ …
