Step-by-step explanation:
The objective is to state whether or not the following limit exists
                                  .
.
First, we simplify the expression in the numerator of the fraction. 

Now, we obtain
                          
and the fraction is transformed into 
                        
Therefore, the following limit is 
        
You can plug in  in the equation, hence
 in the equation, hence
