Derivatives of logarithmic functions are mainly based on the chain rule.However, we can generalize it for any differentiable function with a logarithmic function. The differentiation of log is only under the base e, e, e, but we can differentiate under other bases, too.

If x>0 and y=lnx, then. dydx=1x. If x≠0 and y=ln|x|,then. dydx=1x.

The derivative of the natural logarithmic function (ln[x]) is simply 1 divided by x. This derivative can be found using both the definition of the derivative and a calculator. Derivatives of logarithmic functions are simpler than they would seem to be, even though the functions themselves come from an important limit in Calculus.

When f is a function f(x) of a real variable x, and takes real, strictly positive values, this is equal to the derivative of ln(f), or the natural logarithm of f. This follows (lnx)′=1x.

Take a derivative of both sides of ey = x to get dy. cos nx.

As we can see, taking the derivative of ln requires differentiating the function inside of the natural log and dividing that by the function inside of the natural log. Here are two example problems showing this process in use to take the derivative of ln.
