 ( Tan X + COt Y)  /  Tan X COT Y =                                             =               TAN Y + COT X
 
 ( Tan X + Cot Y )/ (Sin X/CosX) CosY / SinY)
 
 
(Cos X Sin Y ) ( Tan X + Cot Y) =
       Cos X COSY
 
Sin X SinY + Cos X Cos Y  =
     sin x . cosy
 
    Tan Y + Cot X                     = Tan Y + Cot X

lol.  good spot on him missing the brackets on (TanX + CotY)....so so important.
 
I think you have a typo on line 3.  Should be SinXCosY in den.
 
Good job tho.
