WebJul 2, 2016 · Explanation: Let θ = π 5, then 5θ = π. and 3θ = π − 2θ. Note #theta) is an acute angle. Hence sin3θ = sin(π −2θ) but as sin(π −A) = sinA. This can be written as. sin3θ = sin2θ expanding them. or 3sinθ − 4sin3θ = 2sinθcosθ. as θ = π 5 we have sinθ ≠ 0 and dividing by it we get. WebPrecalculus questions and answers. 4. (6 pts.)
