Definition:Exponential Function/Real/Limit of Sequence

Definition
Let $\exp: \R \to \R_{>0}$ denote the (real) exponential function. The exponential function can be defined as the following limit of a sequence:
 * $\exp x := \displaystyle \lim_{n \to \infty} \left({1 + \frac x n}\right)^n$

for all $x \in \R$.

The number $\exp x$ is called the exponential of $x$.
