\begin{definition}[Definition:Sawtooth Wave/Graph]
Let $S$ be the sawtooth wave defined as:
:$\forall x \in \R: \map S x = \begin {cases}
x & : x \in \openint {-\lambda} \lambda \\
\map S {x + 2 \lambda} & : x < -\lambda \\
\map S {x - 2 \lambda} & : x > +\lambda \end {cases}$
The graph of $S$ is given below:
