This value is entered as the average speed at the 5 sec. This paper presents a method to short circuit current of an abscissa compensation circuit.ġ7. The ν-principle is roughly an appropriate transformation of the abscissa of the clearance curve.ġ8. Therefore, on the complex plane, robust stability can be formulated by minimization of pseudospectra abscissa.ġ9. The presence of an adventitious distal abscissa in the forewing venation of honey bees is recorded.Ģ0. Plot this ratio on the abscissa and on the ordinate the ratio of the corresponding massesĢ1. This paper presents a method to calculate the short circuit current of an abscissa compensation circuit.Ģ2. If the ranking of the abscissa is respected on the ordinates, then the chart is reliable.Ģ3. Method and device for the illustration of ordinate/ abscissa value pairs on a display unitĢ4. Of course, this setting only takes effect if the abscissa is displaying a Zero - line. By convention the geologist plots coarse grains to the left of the abscissa and fine to the right.Ģ6. Used in this way, the abscissa can be thought of as a coordinate-geometry analog to the independent variable in a mathematical model or experiment (with any ordinates filling a role analogous to dependent variables).In that case time is plotted along the abscissa and vertical position (depth, height, pressure) along the ordinate.Ģ7. 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 use of the word “ordinate” is related to the Latin phrase “linea ordinata appliicata”, or “line applied parallel”. Maybe the word appears in translations of the Apollonian conics, where Book I, Chapter 20 there is mention of ἀποτεμνομέναις, for which there would hardly be a more appropriate Latin word than abscissa. ![]() We know of no earlier use of the word abscissa in Latin original texts. Īt the same time it was presumably by that a word was introduced into the mathematical vocabulary for which especially in analytic geometry the future proved to have much in store. Vielleicht kommt das Wort in Uebersetzungen der Apollonischen Kegelschnitte vor, wo Buch I Satz 20 von ἀποτεμνομέναις die Rede ist, wofür es kaum ein entsprechenderes lateinisches Wort als abscissa geben möchte. Wir kennen keine ältere Benutzung des Wortes Abscisse in lateinischen Originalschriften. Gleichwohl ist durch vermuthlich ein Wort in den mathematischen Sprachschatz eingeführt worden, welches gerade in der analytischen Geometrie sich als zukunftsreich bewährt hat. In his 1892 work Vorlesungen über die Geschichte der Mathematik (" Lectures on history of mathematics"), volume 2, German historian of mathematics Moritz Cantor writes: Though the word "abscissa" (from Latin linea abscissa 'a line cut off') has been used at least since De Practica Geometrie published in 1220 by Fibonacci (Leonardo of Pisa), its use in its modern sense may be due to Venetian mathematician Stefano degli Angeli in his work Miscellaneum Hyperbolicum, et Parabolicum of 1659. ![]() The ordinate of a point is the signed measure of its projection on the secondary axis, whose absolute value is the distance between the projection and the origin of the axis, and whose sign is given by the location on the projection relative to the origin (before: negative after: positive). ![]() 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 of the axis, and whose sign is given by the location on the projection relative to the origin (before: negative after: positive). ə/ plural abscissae or abscissas) and the ordinate are respectively the first and second coordinate of a point in a Cartesian coordinate system:Ībscissa ≡ x ![]() 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. 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).
