Derivative of General Logarithm Function: Also presented as
This result can also be seen presented as:
- $\map {\dfrac \d {\d x} } {\log_a x} = \dfrac 1 {x \ln a}$
where $\ln a := \log_e a$ is the natural logarithm of $a$.
This is seen to be equivalent to the given form by Logarithm of Reciprocal:
- $\dfrac 1 {\ln a} = \log_a e$
