HELP!! What is the exact value of Tangent (pi/12)
Vlad1618 [11]

Answer:

2 - sqrt(3)

Step-by-step explanation:

Split pi/12 into two angles where the values of the six trigonometric functions are known.

tan (pi/4 - pi/6)

Apply the difference of angles identity

\frac{tan(pi/4) - tan(pi/6)}{1 + tan(pi/4)tan(pi/6)}

tan(pi/4) = 1 , tan(pi/6) = (sqroot3)/3

Plug in and Simplify

\frac{1-\frac{\sqrt{3} }{3} }{1+1\frac{\sqrt{3} }{3} }

\frac{\frac{3-\sqrt{3} }{3} }{\frac{3+\sqrt{3} }{3} }

\frac{3-\sqrt{3} }{3} *\frac{3}{3+\sqrt{3} }

\frac{3-\sqrt{3} }{3+\sqrt{3}} Need to multiply this by \frac{3+\sqrt{3} }{3+\sqrt{3} }

Expand and simplify numerator: \frac{6}{(3+\sqrt{3} )^{2} }

Expand and simplify denominator: \frac{6}{12+6\sqrt{3}}

Cancel the common factor: \frac{1}{2+\sqrt{3}}
