12/16/2023 0 Comments Definition abscissaə/ plural abscissae or abscissas) and the ordinate are respectively the first and second coordinate of a point in a Cartesian coordinate system:Ībscissa \displaystyle In mathematics, the abscissa ( / æ b ˈ s ɪ s. The distance of a point from the x-axis scaled with the y-axis is called the ordinate or y coordinate of the point.įor example, if (x, y) is an ordered pair in the Cartesian plane, then the first coordinate in the plane (x) is called the abscissa and the second coordinate (y) is the ordinate. The distance of a point from the y-axis, scaled with the x-axis, is called the abscissa or x coordinate of the point. In common usage, the abscissa refers to the ( x) coordinate and the ordinate refers to the ( y) coordinate of a standard two-dimensional graph. The first value in each of these signed ordered pairs is the abscissa of the corresponding point, and the second value is its ordinate. Porrò ipsum Paradisi locum audiui à tribus plagis, orientali, meridionali, et septentrionali, inaccessibilem tam hominibus quàm bestijs, eo quòd apparet ripis perpendiculariter abscissa, tanquam inestimabilis altitudinis.Illustration of a Cartesian coordinate plane, showing the absolute values (unsigned dotted line lengths) of the coordinates of the points (2, 3), (0, 0), (–3, 1), and (–1.5, –2.5). No Country For Old Men McCarthy, Cormac, 1933- 2005 The raw rock mountains shadowed in the late sun and to the east the shimmering abscissa of the desert plains under a sky where raincurtains hung dark as soot all along the quadrant. When reading the mathematical psychology textbook, I was puzzled by the fact that all the choice problems were described in terms of gains and losses (actually, almost always gains), whereas the utility functions that were supposed to explain the choices were drawn with wealth as the abscissa. The Volokh Conspiracy » Would love comments: 2007 The line in the figure represents a distribution, with the abscissa representing “policy” or some aspect of a policy on a numerical scale. Recently a Lovely new idea has arisen, that global cooling always occurs where Al Gore speaks, since Al usually speaks all over this planet and not too often from 元, this at least the abscissa seems reasonable. World-wide Campaign Sheds New Light on Nature's "LHC" | Universe Today 2010 we will try to mimic a situation where there is no influence on this horizontal plane. The problem with matter is that it has dimensions and that the particles are not exactly on the same distance along the curvilinear abscissa within the gravitational field. When you say “ abscissa” your mouth opens sideways. One such event is shown on the picture on the right: they infer that an air shower passed through the detector by observing The number of muons seen underground is an excellent estimator of the energy of the primary cosmic ray, as the Kascade collaboration result shown on the left shows (on the abscissa is the logarithm of the energy of the primary cosmic ray, and on the y axis the number of muons per square meter measured by the detector). The independent - variable coordinate (usually x) of a point on the Cartesian plane is called the abscissa, and the dependent-variable coordinate (usually y) is called the ordi - nate. The curve also applies if the abscissa is changed to ‘Amount in Savings’. noun the value of a coordinate on the horizontal axis.noun (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.įrom WordNet 3.0 Copyright 2006 by Princeton University.In the system of Cartesian coördinates, a certain line used in determining the position of a point in a plane.įrom the GNU version of the Collaborative International Dictionary of English. 1), in the parabola PAC, AM, the part of the axis AB cut off by the ordinate PM, is the abscissa of the point P. noun In mathematics: In the conic sections, that part of a transverse axis which lies between its vertex and a perpendicular ordinate to it from a given point of the conic.noun The coordinate representing the position of a point along a line perpendicular to the y-axis in a plane Cartesian coordinate system.From The American Heritage® Dictionary of the English Language, 5th Edition.
