Calculate the derivative of .
Since f(x) is the product of two functions and
, the derivative will require the rule.
Recall the product rule for computing derivatives.
If and g and h are differentiable functions, then
.
Let where
and
.
Find and
.
,
where n = .
Substitute and
appropriately in the product rule to calculate the derivative of
.
Another (easier) way of differentiating f(x) is to first multiply using FOIL and simplfy.
