கொடுக்கப்பட்டது:

A = 60° மற்றும் B = 30°

பயன்படுத்தப்படும் சூத்திரம்:

Tan 60° = √3

Tan 30° = 1/√3

கணக்கீடு:

⇒ (tan 60° - tan 30°)/(1 + tan 60° × tan 30°)

⇒ {√3 - (1/√3)}/{1 + (√3 × 1/√3)}

⇒ {(3 - 1)/√3)}/{1 + 1}

⇒ 2/√3/2 = 

∴ சரியான பதில் .

Shortcut Trick
கணக்கீடு:

⇒  = tan (A - B)

⇒  = tan (60 - 30)

⇒  = tan 30°

⇒  = .

∴ சரியான பதில் .
