Best ResponseYou've already chosen the best response.1we can write your function as below: \[\begin{gathered} \tan \left( {2x  \pi } \right) = \frac{{\tan \left( {2x} \right)  \tan \pi }}{{1 + \tan \left( {2x} \right)\tan \pi }} = \hfill \\ \hfill \\ = \tan \left( {2x} \right) = \frac{{\sin \left( {2x} \right)}}{{\cos \left( {2x} \right)}} \hfill \\ \end{gathered} \]
