abscissa

 [ab-sis´ah]
the horizontal line in a graph along which are plotted the units of one of the variables considered in the study, as time in a time-temperature study. The other line is called the ordinate.
Axes of graph showing normal distribution curve.

ab·scis·sa

(ab-sis'ă),
In a plane cartesian coordinate system, the horizontal axis (x). Compare: ordinate.

The lines intersect the straight hyperbolas at two points, and also intersect the real axis and the abscissa axis where they intercept different lengths.
To determine the abscissa of the intersection points, we calculate the equation of a straight line of each element.
It is even possible to make a refinement of this cutting by reducing the width of the bands removed: The idea is to keep, from series of successive abscissas cutting, only the abscissa of the middle: If [I, I+1, .
One approach is to use segmentation abscissas to operate this recovery: each couple segmentation abscissas delimit a character.
Managing curvilinear abscissa provides such a parametric representation of street axes.
The first element of the N-tuples is the variable S_NameStart, which is the curvilinear abscissa of the beginning of the name.
However, special collocation of abscissas may result in reducing coefficients in the estimates when increasing n.
This leads to a spectral method based exactly on the Radau abscissas.
Apparently, the ordinate of the curves is equal to unity, while the abscissa is 600.
However, there is some increase in the ordinates because the abscissa in Fig.
0006756 a) columns 4 and 5 contain coordinates of peaks of rectangular hyperbolas of elements; b) in a column 6 are presented abscissas the secants which are starting with the peak center (0,1) up to crossings with line Y = 0:5; at prolongation they cross the valid axis in points peaks; c) in a column 7 are resulted abscissa points of crossing of a direct and adjacent hyperbola each element presented here; d) the column 8 contains a difference between sizes of 6 and 7 columns; e) in a column 9 tangents of a corner of an inclination of secants are resulted; at an element "rhodium" this line crosses an axis X in a point with abscissa, equal 411.
In conformity therewith, the magnitude of the abscissa, between a secant and a point of intersection of hyperbolas on the line Y = 0.
