 (tanx+cotx)/(cscxcosx)=sec^2x

 

sin x  / cos x + cosx  /sin x

_______________________   =  

       (1/sin x)( cos x)

 

(sin^2x  +  cos ^2x) / (sinx cosx)

____________________________   =

         (cos x / sinx)

 

                        1

_______________________     =

    (cos x/ sinx)  (sinx cos x)

 

                       1

________________________=

                cos ^ 2  x

 

 

         sec^2 x       =     (RHS)

 

 

cool cool cool
