Sorry man. I got it simplified down to

1/(sin(x)*cos(x))=cot(x)+tan(x)

Maybe this?

csc(x)/cos(x) = cot(x) + tan(x)  ?

2 csc 2x = cot x + tan x

 

2/ [sin (2x) ] = cosx/sinx  + sinx/ cosx   

 

Get a common denominator on the right,  use an identity on the left

 

2 /  [ sinxcos x + sinxcosx]  =  [  cos^2x + sin^2x] / [sinx cosx]

 

2/ [ 2sinxcosx] = 1/ [sinxcosx]       the 2's on the LHS "cancel".....and we're left with

 

1/ [sinxcosx] =  1/ [sinxcosx]

 

 

 

cool cool cool
