# What are the first and second derivatives of #f(x)=ln(x-2)/(x-2) #?

This is a quotien, so we apply the quotient rule here to have the first derivative of this function.

We do it again in order to have the 2nd derivative of the function.

The first derivative of ( f(x) = \frac{\ln(x-2)}{x-2} ) is ( f'(x) = \frac{1}{x(x-2)} ). The second derivative is ( f''(x) = -\frac{1}{x^2} + \frac{1}{(x-2)^2} ).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
