It is not uncommon even today for some people to refer to the x-axis of the Cartesian plane as the Abscissa and the y-axis as the Ordinate.This page is derived from the original publication listed below, whose author(s) should always be credited. 31 “'Tis required to find the relation of the Fluxion of the Ordinate to the Fluxion of the Abscisse.” Leibniz used the term ordinata in 1692 in Acta Eruditorum 11 (Struik, page 272).įor the word in English the OED has a passage from 1706: H. Leibniz used the phrase "per differentias ordinatarum" in a letter to Newton on J(Scott, page 155). Cajori (1906, page 185) writes: "The Latin term for 'ordinate,' used by Descartes comes from the expression lineae ordinatae, employed by Roman surveyors for parallel lines.Ĭajori (1919, page 175) writes: "In the strictly technical sense of analytics as one of the coördinates of a point, the word "ordinate" was used by Leibniz in 1694, but in a less restricted sense such expressions as "ordinatim applicatae" occur much earlier in F. The earliest known uses of the word 'ordinate' in Mathematics seem to be describing an ordered line:
The word 'ordinate' derives from Latin 'ordinare' meaning to arrange or order. A coordinate represents a pair (in 2-d) of 'ordinates' or, more specifically, a pair of numbers, each along an axis.
