the components of research by which a place, as of a curve, is referred to a method of fixed rectilineal coördinate axes.

In mathematics: in conic sections, that section of a transverse axis which lies between its vertex and a perpendicular ordinate to it from certain point of the conic. Hence (fig. 1), in parabola PAC, have always been, the part of the axis AB cut off by the ordinate PM, could be the abscissa regarding the point P. when you look at the system of Cartesian coördinates, a certain line utilized in deciding the position of a place in an airplane.

the value of a coordinate regarding horizontal axis
