# What is DERIVATIVE OF LNX X?

Derivative of the Logarithm Function y = ln x. The derivative of the logarithmic function y = ln x is given by: d/(dx)(ln\ x)=1/x You will see it written in a few other ways as well. The following are equivalent: d/(dx)log_ex=1/x

Use logarithmic differentiation to find the derivative of Y with respect to the given independent variable y = (lnx)^lnx thanks!
The base-10 log function is just ln(x) / ln(10). Either base would work for taking the x out of﻿ the exponent, but the derivative of ln(x) is 1/x, and the derivative of log(x) is 1/(x * ln(10)), so using the natural log avoids introducing a purposeless factor of 1 / ln(10).
I have to find the second deriviative of f(x)=ln(√x). This is what I have done for the first derivative, but I got stuck before I could get to the second derivative!! Thanks for any help you can give! f(x)=ln(√x) =ln(x^(1/2)) =1/x^(1/2) * (1/2)x^(-1/2)
