Ordinate represents geo-electric excitation; abscissa, distance from upper surface of flower stalk.
The abscissa of such a curve is the reading of the instrument to be corrected.
To provide for such cases the curve is drawn as if it never touched the abscissa.
A Thermo-crescent Curve is thus obtained, the ordinate of which represents increment of growth, and the abscissa, the time.
The measured lengths are marked off on ordinates erected on an abscissa, along which the times are noted.
The ordinate of the curve represents the intensity of response, and the abscissa the time (fig. 1).
Thus we find the curve at first slightly convex, then straight and ascending, and lastly, concave to the abscissa (fig. 30).
The ordinate in these curves represents the E.M. variation, and the abscissa the time.
Newton denoted the moment of the abscissa by o, that of the area z by ov.
The curve as a whole becomes, first slightly convex to the abscissa, then straight and ascending, and lastly concave.
| abscissa Plural abscissas or abscissae (āb-sĭs'ē) The distance of a point from the y-axis on a graph in the Cartesian coordinate system. It is measured parallel to the x-axis. For example, a point having coordinates (2,3) has 2 as its abscissa. Compare ordinate. |
mathematics
The horizontal or x coordinate on an (x, y) graph; the input of a function against which the output is plotted.
The vertical or y coordinate is the "ordinate".
See Cartesian coordinates.
