QUESTION 25. TRIGONOMETRIC EQUATIONS (Late Middle Palaeolithic). θ = s/60 × 2π 8sin^2(θ) + 2sin(θ) – 1 = 0 2cos^2(θ) + √3cos(θ) = 0 a. Solve for θ and s. (Note: there are several possible θ values, find the specific angle that corresponds to both sine and cosine). 8sin^2(θ) + 4sin(θ) – 2sin(θ) – 1 = 0 4sin(θ)(2sin(θ) […]
