Apply the quotient rule, which is:
and .
To find :
Differentiate term by term:
The derivative of the constant is zero.
Apply the power rule: goes to
The result is:
To find :
Apply the power rule: goes to
Now plug in to the quotient rule:
Now simplify:
The answer is:
/ 2\ | -1 + x | 2*|-1 + -------| | 2 | \ x / ---------------- x
/ 2\ | -1 + x | 6*|1 - -------| | 2 | \ x / --------------- 2 x
