Question

Evaluate : 2tan30°/1-tan^2 30°=?

Answer 1

Answer:

The value of

$\frac{2tan30}{1-tan^{2}30}$ = $\sqrt{3}$

Step-by-step explanation:

______________________

we know that,

$\boxed {\frac{2tanA}{1-tan^{2}A}=tan2A}$

______________________

Here ,

A = 30°

$\frac{2tan30}{1-tan^{2}30}$

= $tan(2\times 30)$

= tan60°

= $\sqrt{3}$

Therefore,

The value of

$\frac{2tan30}{1-tan^{2}30}$ = $\sqrt{3}$
