First qiestion is $Tan^{-1} 2x/1-x^2$ ....

Now put x = tan $\Theta$ ...

So $\Theta = tan^{-1}x$ ................(1).....

So the qiestion becomes....

$tan^{-1}(2tan\Theta/1- tan^{2}\Theta )$ …

That is.... $tan^{-1}(tan2\Theta)$ ...

That is... $2 \Theta$ ... = $2tan^{-1}x...$ from (1)...

Hope you have understood it...
