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. Waterhouse slashes an abscissa and an ordinate onto the board, then sweeps out a bell-shaped curve.1. I got down my old text for analytical geometry, from Thebes High School, measured some ordinates, abscissas, and slopes - plugged in the figures and wrote down the equation. I found that with each mixture there was a time of exposure which would produce the deepest blue, that with over-exposure the blue gradually turned gray, and that if a curve should be plotted, the abscissas of which should represent the time of exposure, and the ordinates of which should represent the intensity of the blue the curves drawn would have approximately an elliptical form, so that if one knew the exact time of exposure which would give the best result with any mixture, one might deviate two or three minutes either way from that time without producing a noticeable result. 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.īy the end of the day, the sand is crisscrossed with a mesh of ordinates, abscissas, curves to account for everything in nature.

Such a line has for abscissa the distance of a load from one end of a girder, and for ordinate the bending moment or shear at any given section, or on any member, due to that load.
#ABSCISSA DEFINITION CODE#
She paced restlessly while he worked at making a graph with time as the abscissa and the code numbers for ordinates. Kyros disappeared from the great screen and was replaced by a grid on which each radiational component of the strange shell of energy was plotted on the ordinate against the abscissa of time. In this cause-and-effect curve, the first part is slightly convex to the abscissa, the second straight and ascending, and the third concave. The curve as a whole becomes, first slightly convex to the abscissa, then straight and ascending, and lastly concave. OY or PX its ordinate, the intersecting lines OX and OYīeing the axes of abscissas and ordinates respectively, OX or PY is the abscissa of the point P of the curve, Ordinates taken together are called cordinates. Measured parallel to either of them, from the point to When a point in space is referred to three axes havingĪ common intersection, the abscissa may be the distance Line drawn through it and parallel to the axis of Y. Point is the distance cut off from the axis of X by a The axis of ordinates, or of Y, the abscissa of the Note: When referred to two intersecting axes, one of themĬalled the axis of abscissas, or of X, and the other One of the elements of reference by which a point, as of aĬurve, is referred to a system of fixed rectilineal
