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 for f. Using that the derivative of f − 1 is the ratio of the change in its output to the change in its input, we can conclude that WebThis rule for the natural logarithm function now joins our list of basic derivative rules.
