WebMar 1, 2024 · The three most popular cosine of a double angle equations are: \cos (2\cdot\theta)=\cos^2 (\theta)-\sin^2 (\theta) cos(2 ⋅ θ) = cos2(θ) − sin2(θ) Which involves both the sine and the cosine; \cos (2\cdot\theta)=2\cdot\cos^2 (\theta)-1 cos(2 ⋅ θ) = 2 ⋅ cos2(θ) − 1 Or its alternative with the sine: WebExample 1: Determine the value of sin 150° using cofunction identities. Solution: To find the value of sin 150°, we will use the formula sin θ = cos (90° - θ). So, we have sin 150° = cos (90° - 150°) = cos (-60°) = cos (60°) --- [Because cos (-x) = cos x for all x.] = 1/2 --- [Because cos 60° = 1/2] Answer: sin 150° = 1/2
