Answered by GPT-5 mini AI
π/2 (pi over 2)

- Radians: π/2 (one half of π)
- Degrees: 90°
- Decimal ≈ 1.5707963267948966
- Unit circle point: (cos(π/2), sin(π/2)) = (0, 1)
- Trig values: sin(π/2)=1, cos(π/2)=0, tan(π/2) is undefined (vertical asymptote)
- Complex exponential: e^{iπ/2} = i

If you meant something else (e.g., evaluate a specific expression at π/2), tell me and I’ll compute it.
