$\tan (2 x) = \frac{2 - \frac{\sqrt{119}}{5}}{1 - \tan^{2} (- \frac{\sqrt{119}}{5})}$

Step 1

Graph each side of the equation.

$y = \tan (2 x)$

$y = \frac{2 - \frac{\sqrt{119}}{5}}{1 - \tan^{2} (- \frac{\sqrt{119}}{5})}$

Step 2

$[\begin{array}{c} x^{2} & \frac{1}{2} \\ \sqrt{π} & \int x d x \end{array}]$
