ln x
Definition
The natural logarithm function, denoted as ln x, is the inverse of the exponential function e^x. It gives us the power we need to raise Euler's number (e) to obtain x.
Analogy
Imagine you have a superpower that can tell you how many times you need to multiply Euler's number (e) by itself to get a certain value. That superpower is called ln x!
