Natural Exponential & Logarithmic Functions
The Number e was first used by mathematician Leonard Euler to represent the base of natural logarithm in a letter to another mathematician, Christian Goldbach, in 1731.
In many applications the most convenient choice for a base is the irrational number
e ≈ 2.718281828... this is called the natural base.
The function f (x) = ex is called the natural exponential function.
