Definition:Half-Plane/Open/Right

Definition
Let $P$ denote the plane implemented as a Cartesian system.

Let $L$ be the $y$-axis.

The open right half-plane $H_{\text {OR} }$ is the area of $P$ on the right of $L$.

That is, where $x > 0$:


 * $H_{\text {OR} } := \set {\tuple {x, y}: x \in \R_{>0} }$
