Option 1: $\cos 60°$
Option 2: $\tan 60°$
Option 3: $\sin 60°$
Option 4: $\sin 30°$
Correct Answer: $\sin 60°$
Solution : Given, $\frac{2 \tan 60°}{1+\tan ^2 60°}$ $=\frac{\frac{2\sin60°}{\cos60°}}{1+\frac{\sin^260°}{\cos^260°}}$ $=\frac{2\sin60°\times\cos^260°}{\cos60°(\cos^260°+\sin^260°)}$ $=\frac{2\sin60°\cos60°}{1}$ [As $\cos^2\theta+\sin^2\theta=1$] $=2\times\frac{\sqrt3}{2}\times\frac12$ $=\frac{\sqrt3}{2}=\sin60°$ Hence, the correct answer is $\sin60°$.
