For any point, the abscissa is the first value (x coordinate), and the ordinate is the second value (y coordinate). In mathematics, the abscissa (/ æ b ˈ s ɪ s. ə /; plural abscissae or abscissas) and the ordinate are respectively the first and second coordinate of a point in a Cartesian coordinate system: [1] [2]
Standard names for the coordinates in the three axes are abscissa, ordinate and applicate. [9] The coordinates are often denoted by the letters x, y, and z. The axes may then be referred to as the x-axis, y-axis, and z-axis, respectively. Then the coordinate planes can be referred to as the xy-plane, yz-plane, and xz-plane.
In the diagram, the abscissa (horizontal axis) represents two variables with different scales to represent both the solid phase mole fraction and the aqueous activity fraction. The ordinate (vertical axis) represents the solid phase. [4] There are two variants of Lippmann diagrams: [citation needed] Ion-activity Lippmann diagram
When the abscissa and ordinate are on the same scale, the identity line forms a 45° angle with the abscissa, and is thus also, informally, called the 45° line. [5] The line is often used as a reference in a 2-dimensional scatter plot comparing two sets of data expected to be identical under ideal conditions. When the corresponding data points ...
Measles cases are rising in the U.S. with infections confirmed in at least five states so far this year. Cases have been reported in Alaska, Georgia, New York City, Rhode Island and Texas, mostly ...
Although the mathematical notion of function was implicit in trigonometric and logarithmic tables, which existed in his day, Leibniz was the first, in 1692 and 1694, to employ it explicitly, to denote any of several geometric concepts derived from a curve, such as abscissa, ordinate, tangent, chord, and the perpendicular (see History of the ...
Over the last few days, thousands of contractors, including those who function as diplomats abroad, have been put on leave or locked out of critical agency systems, including those that alert them ...
Amazon on Thursday reported better-than-expected revenue and profits for the holiday shopping period, but its stocks dipped in after-hours trading due to disappointing guidance for the current ...
