Best ResponseYou've already chosen the best response.0Working on the left hand side, you get: \[\frac{ 1 }{ \tan (x\frac{ \Pi }{ 2 }) }\] After that, follow the property that:\[\tan(AB)=\frac{ tanAtanB }{ 1+tanAtanB }\] Giving us: \[\frac{ 1 }{ \frac{ tanx\tan \frac{ \Pi }{ 2 } }{ 1+tanxtan \frac{ \Pi }{ 2 } } }=\frac{ 1+tanxtan \frac{ \Pi }{ 2 } }{ tanx\tan \frac{ \Pi }{ 2 } }\]

Best ResponseYou've already chosen the best response.0or you could convert cot into cos/sin and directly use, cos (xpi/2) = sin x sin (xpi/2) = cos x
