has equation 
Step-by-step explanation
Step 1.
We need to find
if and .
and .Applying The Quotient Rule :
If 
and 
are differentiable, then
and are differentiable, then
since both function 
and 
are differentiable and 
, we obtain
and are differentiable and , we obtain
Replacing the given values it follows
