Find the derivative of
You can treat y as a composite function of x:
so use the chain rule to differentiate y:
The first derivative is 1/u, and the second one can be evaluated by applying the quotient rule:
Multiply out those terms in parentheses:
Substitute back for
Simplifying that product, you get
∴
I hope this helps. =)
