Cartesian coordinates
The Cartesian coordinates^{} of a point in ${\mathbb{R}}^{3}$ for determining its in threedimensional space are the three real numbers $x$, $y$ and $z$, which are called

•
$x$coordinate or abscissa,

•
$y$coordinate or ordinate,

•
$z$coordinate or applicate.
The last name “applicate” is rare in English, but its in continental European , as “die Applikate” in German and “aplikaat” in Estonian, are more known.
Similarly, in ${\mathbb{R}}^{n}$ for all $n=1,\mathrm{\hspace{0.17em}2},\mathrm{\hspace{0.17em}3},\mathrm{\dots}$ one needs $n$ coordinates for specifying the location of a point.
