Derivatives of natural logarithms

WebSince the natural logarithm is the inverse of the exponential function, we can write f − 1 as x = f − 1 ( y) = ln ( y). We can represent the derivative of f − 1 in the same was as we did … WebHence, the derivatives of logs are: d/dx (logₐ x) = 1 / (x ln a) (this is the derivative of common logarithm) d/dx (ln x) = 1/x (this is the derivative of natural logarithm) Derivative of log x Proof by First Principle We will prove that d/dx (logₐ x) = 1/ (x ln a) using the first principle (definition of the derivative). Proof:
