cos(2*pi/5) - Wolfram Alpha
WebDec 11, 2024 · (2) cos(2π 5) = ω + ω − 1 2, and 4(ω + ω − 1 2)2 + 2(ω + ω − 1 2) − 1 = 0. So the minimal polynomial for cos(2π 5) is 4x2 + 2x − 1. (3) The roots of 4x2 + 2x − 1 are − 1 ± √5 4, and cos(2π 5) > 0, so cos(2π 5) = √5 − 1 4. It follows that sin(2π 5) = √√5 + 5 8. For simplicity, let's let α = sin(2π 5) = √√5 + 5 8. So we have that α2 = √5 + 5 8. Web6. 11.
