Question

The value of $\frac{2\tan {30}^{\circ }}{1-{\tan }^2{30}^{\circ }}$ is $\sqrt{3}$.Is it true ? If true enter 1 else 0.

Answer 1

$\left(\frac{2tan{30}^0}{1-ta{n}^2{30}^0}\right)=\tan (2\times {30}^0)=tan{60}^0=\sqrt{3}$

$formulaused\left(\frac{2tan\theta }{1-ta{n}^2\theta }\right)=tan2\theta$
