### Abscissa

==In parametric equations== In a somewhat obsolete variant usage, the abscissa of a point may also refer to any number that describes the point`s location along some path, e.g. the parameter of a parametric equation. Used in this way, the abscissa can be thought of as a coordinate-geometry analog to the independent variable in a mathematical mode....
