\begin{definition}[Definition:Exponential Function/Complex/Limit of Sequence]
Let $\exp: \C \to \C \setminus \set 0$ denote the '''(complex) exponential function'''.
The '''exponential function''' can be defined as a limit of a sequence:
:$\ds \exp z := \lim_{n \mathop \to \infty} \paren {1 + \dfrac z n}^n$
The complex number $\exp z$ is called the '''exponential of $z$'''.
