((2 tan 30^@)/(1-tan^2 30^@)) =?

(2 tan 30^(@))/(1 + tan^(2)30^(@)) =

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

Verify that: sin60o=(2tan30o)/(1+tan^(2)30o)=(sqrt(3))/(2) (ii) cos60o=(1-tan^(2)30o)/(1+tan^(2)30o)=(1)/(2)

(2tan30o)/(1-tan^2 30o) is equal to cos60o (b) sin60o (c) tan60o (d) sin30o

(2tan30o)/(1+tan^2 30o) is equal to sin60o (b) cos60o (c) tan60o (d) sin30o

If (x-xtan^(2)30^(@))/(1+tan^(2)30^(@))=sin^(2)30^(@)+4cot^(2)45^(@)-sec^(2)60^(@) , then the value of x is :

Prove (1-sin60^(@))/(cos60^(@))=(1-tan30^(@))/(1+tan30^(@))
