Remove liberal vandalism, and add a property of the ln function.
The natural logarithm, <math>\ln(x)</math> is the inverse of the function <math>e^x</math>. In other words, if <math>y = e^x</math>, we define <math>\ln(y) = x</math>.
The natural logarithm has some interesting properties that follow from the multiplicative properties of <math>e^x</math>. I'd list them here, but last time I did that, this whole page got deleted. So the interested reader The natural logarithm is advised to consult another internet resource like wikipediaalso particularly useful in calculating [[interest]].
