But now I need to find cos (alpha/2) to be able to use the Half-Angle ... WebUsing trigonometry formulas, we can represent the cos pi as: ± √ (1-sin² (pi)) ± 1/√ (1 + tan² (pi)) ± cot (pi)/√ (1 + cot² (pi)) ±√ (cosec² (pi) - 1)/cosec (pi) 1/sec (pi) Note: Since pi lies on the negative x-axis, the final value of cos pi is -1. We can use trigonometric identities to represent cos pi as, -cos (pi - pi) = -cos 0
