I don't know what direction to take to try and answer it .

 I describe below that 1 + Cot X can only be converted to ( SinX + Cos X )/ Cos X, which is not much of a simplification.
 
  1 + Cot^2 X  can be simplified  to one term of CSC ^2 X .
 
  The direction is taken is to write down expression in terms of other trigonometric functions.
 
    Like   Cot X = SinX / CosX

 The direction here is not given, normally comes into form of identity.
 
     1 + CotX = 1 + sinX/ CosX =( CosX + SinX )/ CosX
 
 
       If it was  1 + Cot ^2X
 
       then:
 
       1 + Cot^2 X
 
       1 + Cos^2  X / Sin ^2  X = ( Sin^2X + Cos^2 X) / Sin^2 X = 1/ Sin^2X = CSC^2 X
