Best ResponseYou've already chosen the best response.1remember tan =sin /cos so you can write tan in terms of sin/cos

Best ResponseYou've already chosen the best response.1\[\large \rm cot (x  \frac{ \pi }{ 2 }) =\frac{ \cos( \frac{ \pi }{ 2 } x) }{ \sin(\frac{ \pi }{ 2 } x)}\] i guess we have to use this formulas http://prntscr.com/7ywjsc :D and btw i meant to say write cot in terms of cos/sin

Best ResponseYou've already chosen the best response.1and u should remember even/odd formulas \[\cos(  x) = \cos(x)\]\[\sin(x)=\sin(x)\]\[\tan(x)=\tan(x)\]
