வெளிப்பாடு = tan66° tan30° tan24° tan27°/cot63°
பயன்படுத்தப்படும் கோட்பாடு:
cotθ = 1/tanθ
கணக்கீடு:
an66° tan30° tan24° tan27°/cot63° = tan66° × 1/√3 × tan(90° - 66°) × tan(90° - 63°)/cot63°
⇒ tan66° tan30° tan24° tan27°/cot63° = tan66° × 1/√3 × cot66° × cot63°/cot63°
⇒ tan66° tan30° tan24° tan27°/cot63° = 1/√3
∴ tan66° tan30° tan24° tan27°/cot63° இன் மதிப்பு 1/√3.
