This category contains results about Periodic Functions.
Definitions specific to this category can be found in Definitions/Periodic Functions.

Periodic Real Function

Let $f: \R \to \R$ be a real function.

Then $f$ is periodic if and only if:

$\exists L \in \R_{\ne 0}: \forall x \in \R: \map f x = \map f {x + L}$

Periodic Complex Function

Let $f: \C \to \C$ be a complex function.

Then $f$ is periodic if and only if:

$\exists L \in \C_{\ne 0}: \forall x \in \C: \map f x = \map f {x + L}$
