Corollary: Reciprocity of Exponential Function, Non-Zero Property

(related to Proposition: Functional Equation of the Exponential Function)

The exponential function is never zero (non-zero property) \[\exp(x)\neq 0\] for all \(x\in\mathbb R\), and it fulfills the following reciprocity law:

\[\exp(-x)=\frac1{\exp(x)}.\]
