![]() See the etymology of the corresponding lemma form. The abscissa of a point is the signed measure of its projection on the primary axis, whose absolute value is the distance between the projection and the origin. For instance with the point (3, 2) the abscissa is 3 and the ordinate is 2. The abscissa is the first coordinate in an ordered pair and the ordinate is the second coordinate. ![]() Trumble and Angus Stevenson, editors (2002), “abscissa”, in The Shorter Oxford English Dictionary on Historical Principles, 5th edition, Oxford New York, N.Y.: Oxford University Press, →ISBN, page 8.įrom abscissus, perfect passive participle of abscindō ( “ tear away ” ).Ībscissa f ( genitive abscissae) first declension Abscissa Definition In mathematics, the abscissa and the ordinate are respectively the first and second coordinates of a point in a coordinate system. The American Heritage Student Science Dictionary, Second Edition. For example, a point having coordinates (2,3) has 2 as its abscissa. ↑ 1.0 1.1 Lesley Brown, editor-in-chief William R. scissa (b-ss) The distance of a point from the y-axis on a graph in the Cartesian coordinate system.( first of two coordinates ) : coordinate.Originally, it referred to the portion of a line between a fixed point on that line and the intersection of that line with an ordinate. In this example, the value '12' is the abscissa. Grammatically, this word 'abscissa' is a noun, more specifically, a countable noun. abscissa / ( bss) / noun plural -scissas or -scissae (-ssi) the horizontal or x -coordinate of a point in a two-dimensional system of Cartesian coordinates. Meaning of abscissa for the defined word. Always written first in an ordered pair of coordinates such as (12, 5). The definition of abscissa in Dictionary is as: 1.0 1.1 Lesley Brown, The Shorter Oxford English Dictionary, 5th edition (Oxford University Press, 2003. ( geometry ) The horizontal line representing an axis of a Cartesian coordinate system, on which the abscissa (sense above) is shown. The horizontal ('x') value in a pair of coordinates.The point ( 3, 2 ) has 3 as its abscissa and 2 as its ordinate. ( geometry ) The first of the two terms by which a point is referred to, in a system of fixed rectilinear coordinate (Cartesian coordinate) axes.It is the distance measure from Y-axis measured parallel to X-axis. See abscind.Ībscissa ( plural abscissas or abscissae or abscissæ) The coordinates of the X-axis on the cartesian plane is called abscissa. Etymology īy ellipsis from Latin abscissa, feminine of abscissus, perfect passive participle of abscindō ( “ cut off ” ). ![]() ![]() Abscissa - One of the elements of reference by which a point, as of a curve, is referred to a system of fixed rectilineal coordinate axes. Also called x-value (NOTE: The plural is abscissae or abscissas.) Webster Dictionary Meaning 1. The vertical value is the y-value or ordinate. OX or PY is the abscissa of the point P of the curve, OY or PX its ordinate, the intersecting lines OX and OY being the axes of abscissas and ordinates respectively, and the point O their origin.A point in the Cartesian plane x is the abscissa. Abscissa Abscissa is the horizontal value on a graph. Abscissas and ordinates taken together are called coördinates. in the most comprehensive dictionary definitions resource on the web. When a point in space is referred to three axes having a common intersection, the abscissa may be the distance measured parallel to either of them, from the point to the plane of the other two axes. Information and translations of abscissa. When referred to two intersecting axes, one of them called the axis of abscissas, or of X, and the other the axis of ordinates, or of Y, the abscissa of the point is the distance cut off from the axis of X by a line drawn through it and parallel to the axis of Y. (Geom.) One of the elements of reference by which a point, as of a curve, is referred to a system of fixed rectilineal coördinate axes. ![]()
