tan15^(@) + tan 75^(@)=

tan ^ (- 1) (tan15 ^ (@))

The value of (tan15^(@))/(2-sec^(2)15^(@)) is equal to

The value (tan15^(@))/(2-sec^(2)(15^(@))) is equal to

Prove that Tan15^(@)=2-sqrt(3)=Cot 75^@

If tan15^(@)=2-sqrt(3) then value of tan15^(@)cot75^(@)+tan75^(@)cot15^(@) is

If tan15^(@)=2-sqrt(3) , the value of tan15^(@)cot75^(@)+tan75^(@)cot15^(@) is

If tan 15^(@) = 2 - sqrt(3) , then show that 2 tan 1095^(@) + cot 975^(@) + tan (-195^@) = 4 - 2sqrt(3) .

If cos x-(cot beta sinx )/( 2 )=sqrt(3)/(2) , then the value of tan""(x)/(2) is A. tan""(beta)/(2) tan 15^(@) B. tan""(beta)/(2) C. tan 15^(@) D. None of these
