    Do you mean:

    [tex](1-tan^2(x)) * tan(2x) = \frac{2}{\frac{2}{\sqrt{3}}}[/tex]

    And
    [tex]2/(2/root 3)= \frac{2}{\frac{2}{\sqrt 2}}= 2[/tex]

    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 [tex]\sqrt{2}[/tex] and not 2. Double brain fart :tongue2:
