Derivative of natural log rules
WebThe derivative of the natural logarithm function is the reciprocal function. When f ( x) = ln ( x) The derivative of f (x) is: f ' ( x) = 1 / x Integral of natural logarithm (ln) function The integral of the natural logarithm function is given by: When f ( x) = ln ( x) The integral of f (x) is: ∫ f ( x) dx = ∫ ln ( x) dx = x ∙ (ln ( x) - 1) + C 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.
