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. 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 So the point is in quadrant I.Abscissa \Ab*scis"sa\, n.
