|(mathematics, graphics)||Cartesian coordinates - (After Renee Descartes, French
philosopher and mathematician) A pair of numbers, (x, y),
defining the position of a point in a two-dimensional space by
its perpendicular projection onto two axes which are at right
angles to each other. x and y are also known as the
abscissa and ordinate.|
The idea can be generalised to any number of independent axes.
