Homework Help: calculus

Posted by mary on Tuesday, May 3, 2011 at 3:35pm.

Please help. Applying the chain rule, how do I find the derivative of f(x)=In(e^x-e^-x) (x>0) and then using this answer use the quotient rule to find the second derivative. I cannot do this so any answer greatly appreciated.
