Do you mean:

$$(1-tan^2(x)) * tan(2x) = \frac{2}{\frac{2}{\sqrt{3}}}$$

And
$$2/(2/root 3)= \frac{2}{\frac{2}{\sqrt 2}}= 2$$

I believe this is incorrect... shouldn't it be the square root of 3, and not of 2?

And even then... it would be equal to $$\sqrt{2}$$ and not 2. Double brain fart :tongue2:
