Find the vlaue of (2tan30^(@))/(1-tan^(2) 30^(@)) .

The value of (3 tan 30^(@)-tan^(3)30^(@))/(1- 3 tan^(2)30^(@)) is _______

If (2tan^(2)30^(@))/(1-tan^(2)30^(@))+sec^(2)45^(@)-sec^(2)0^(@)=xsec60^(@) , then the value of x is

Choose the correct option and justify your choice :(i)(2tan30^(@))/(1+tan^(2)30^(@))(a)sin60^(@)(b)cos60^(@)(c)tan60^(@)(d)sin30^(@)

(tan 60^(@) - tan 30^(@))/(1 + tan 60^(@) tan 30^(@)) equal
