WebIn this lesson, we are going to see what is the derivative of ln x. We know that ln x is a natural logarithmic function. It means "ln" is nothing but "logarithm with base e". i.e., ln = logₑ. We can find the derivative of ln x in two methods. By using the first principle (definition of derivative) By using implicit differentiation WebDerivative of Logarithm When the logarithmic function is given by: f ( x) = log b ( x) The derivative of the logarithmic function is given by: f ' ( x) = 1 / ( x ln ( b) ) x is the function argument. b is the logarithm base. ln b is the natural logarithm of b. For example when: f ( x) = log 2 ( x) f ' ( x) = 1 / ( x ln (2) ) See also

WebFirstly log (ln x) has to be converted to the natural logarithm by the change of base formula as all formulas in calculus only work with logs with the base e and not 10. Hence log ( ln x ) = ln ( ln x ) / ln (10) and then differentiating this gives [1/ln (10)] * [d (ln (ln x)) / dx].
