________________       =

(1 - t)^2 - ( 1 + t)^2

 

 

             1

_________________________     =

  (1 - 2t + t^2)  - ( 1 + 2t + t^2)

 

 

                 1

_________________                    ( the denominator cannot = 0...... so t cannot equal 0 )

              - 4t

 

Domain =  (-inf , 0) U ( 0 , inf)
