prove (tanx+cotx)/(cscxcosx)=sec^2x
please tell me the order of the options in the picture
(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)
