Prove the trigonometric identity.

 tanx+cotx

_________ =sec^2x

csc x cos x

 

__= sec^2x

__= sec^2x

__ = sec^2x

__= sec^2x

__ = sec^2x

 

1/cos^2x=sec^2x

sec^2x=sec^2x

tan x  +  cot x   

___________  =

csc x cos x

 

(sin x / cos x)  + (cos x / sin x)

_________________________   =

   (1/sin x) * cos x

 

 

sin x / cos x                   cos x / sin x

____________   +       ___________    =

 cos x  / sin x                 cos x / sin x

 

 

 

(sin x / cos x) ( sin x / cosx)    +     1    =

 

sin^2 x

_________     +      1        =

cos^2 x

 

 

tan^2 x   +   1   =

 

 

sec^2 x
