Cot pi/2 is the value of cotangent trigonometric function for an angle equal to π/2 radians. The value of cot pi/2 is 0. 2) Since (n − 2k) is odd, it follows that sin((n − 2k)π + θ) = − sin(θ), and n−1 ... n )cot(π − kπ n ). = − n−1. ∑ k=1 sin ( k2π n )cot ( kπ n ) . it follows that for any even k ≥ 2,.
