$The derivative of the natural logarithm - Math Insight$

WebWhen we take the logarithm of a number, the answer is the exponent required to raise the base of the logarithm (often 10 or e) to the original number. For example log base 10 of 100 is 2, because 10 to the second power is 100. Therefore, the natural logarithm of x is defined as the inverse of the natural exponential function: WebSince the natural logarithm is the inverse of the exponential function, we can write f − 1 as x = f − 1 ( y) = ln ( y).
