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>. The natural logarithm is also particularly useful in calculating interest.
