Category:X-Axis

This category contains results about the $x$-axis.
Definitions specific to this category can be found in Definitions/X-Axis.

In a cartesian coordinate system, the $x$-axis is the one usually depicted and visualised as going from left to right.

It consists of all the points in the real vector space in question (usually either $\R^2$ or $\R^3$) at which all the elements of its coordinates but $x$ are zero.
