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’. The word "abscissa" in example sentences.Horizontal distance from a fixed line to a point Urban DictionaryĪ math term referring to the distance between a point and the y-axis in a graph. The horizontal line representing an axis of a Cartesian coordinate system, on which the abscissa (sense above) is shown. The first of the two terms by which a point is referred to, in a system of fixed rectilinear coordinate (Cartesian coordinate) axes. The value of a coordinate on the horizontal axis noun One of the elements of reference by which a point, as of a curve, is referred to a system of fixed rectilineal coördinate axes. In the system of Cartesian coördinates, a certain line used in determining the position of a point in a plane. 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. 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. The coordinate representing the position of a point along a line perpendicular to the y-axis in a plane Cartesian coordinate system. Then, as this sum or difference is to the abscissa, so is the conjugate to. "To or from the semi-conjugate, according as the greater or less abscissa is. Engineers' and Mechanics' Pocket-book by Charles Haynes Haswell (1844) "The projections of OP are also called coordinates of the point P : and theĬoordinates are distinguished by the names abscissa and ordinate."Ħ. Trigonometry and Double Algebra by Augustus De Morgan (1849) Rn.E.- As either abscissa is lo square of its ordinal*. "When the other Ordinate and abscissae, or other abscissa and Ordinales are given. Mechanics' and Engineers' Pocket-book of Tables, Rules, and Formulas by Charles Haynes Haswell (1920) The abscissa OM and the ordinate MP are together called the coordinates of. "The lines of the figure are named as follows : OM is called the abscissa of. Plane and Spherical Trigonometry by Leonard Magruder Passano (1918) The ordinate of a point are called the coordinates of the point."ģ. "Thus, the abscissa of Pj is OB¡, the ordinate of Pt is OA\.
New School Algebra by George Albert Wentworth (1898) Number x is called the abscissa of P with respect to the origin 0. Let 0 be a fixed point on a line X'OX and P. An Elementary Treatise on the Calculus: With Illustrations from Geometry by George Alexander Gibson (1901) Lexicographical Neighbors of Abscissa abscindedīelow you will find example usage of this term as found in modern and/or classical literature:ġ. 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. Abscissas and ordinates taken together are called coordinates.
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. 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. One of the elements of reference by which a point, as of a curve, is referred to a system of fixed rectilineal coordinate axes. The abscissa is also known as the "x" coordinate of a point, shown on the horizontal line, with the ordinate, also known as the "y" coordinate, shown on the vertical line. (context: geometry) The first of the two terms by which a point is referred to, in a system of fixed rectilinear coordinate (Cartesian coordinate) axes. One of the elements of reference by which a point, as of a curve, is referred to a system of fixed rectilineal coördinate axes.ġ.
