Rfd-redundant

1. (mathematics) Used to denote the third coordinate in three-dimensional Cartesian and cylindrical coordinate systems.

   $x^{2}+y^{2}+z^{2}=1$

2. (analytic geometry, classical mechanics) Quantity along the third axis in a three-dimensional system, vertical when applicable.— This unsigned comment was added by 87.68.161.235 (talk) at 21:21, 24 August 2021 (UTC).

Delete. I agree that the last one is redundant; moreover, “vertical when applicable” is not universally true; in z-buffering the variable $z$ stands for the depth in camera space, which is usually horizontal (from the camera to the object).  --Lambiam 11:59, 25 August 2021 (UTC)
