Yogita Ingle 7 years, 3 months ago

Let tan(15°) = tan(45°-30°)
We know that tan(A - B) = (tanA - tanB) /(1 + tan A tan B)
⇒tan(45°-30°) = (tan45°- tan30°)/(1+tan45°tan30°)
= {1- (1/√3)} / {1+(1/√3)}
∴ tan15° = (√3 - 1) / (√3 + 1)

Keshav Bindal 7 years, 3 months ago

(√3 - 1)/(√3 + 1) = (4 - 2√3)/2 [Rationalise] = 2 - √3
