(2*tan(30^circ))/(tan(30^circ)^2 %2B 1) – InterviewSolution

1.

(2*tan(30^circ))/(tan(30^circ)^2 %2B 1)

Answer»

tan 30 = 1/root(3)

Then,2 tan 30/1 + tan^2 30

= 2* 1/root(3)/ 1 + (1/root(3))^2

= 2/root(3) / 1 + 1/3

= 2/root(3) * 3/4

= root(3)/2

root3/2 is the answer

Bhai answer sin 60° hoga
