# How to use *Abscissa* in a sentence

A curve with I as

**abscissa**and u as ordinate is called the curve of velocities or velocity-time curve.The measured lengths are marked off on ordinates erected on an

**abscissa**, along which the times are noted.Since the curve represents a longitudinal disturbance in air it is always continuous, at a finite distance from the axis, and with only one ordinate for each

**abscissa**.The

**abscissa**is the standard deviation of the relative error on coordinates of image point or calibration parameters.The ordinate to any point upon this curved line then represents on the left-hand scale the maximum continuous yield per day for each acre of drainage area, from a reservoir whose capacity is equal to the corresponding

**abscissa**.AdvertisementThe ordinate of the trapezette will be denoted by u, and the

**abscissa**of this ordinate, i.e.It arises mainly in statistics, when the ordinate of the trapezette represents the relative frequency of occurrence of the magnitude represented by the

**abscissa**x; the magnitude of the**abscissa**corresponding to the median ordinate is then the " median value of x."The statement that the ordinate u of a trapezette is a function of the

**abscissa**x, or that u=f(x), must be distinguished from u =f(x) as the equation to the top of the trapezette.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.As freezing progresses, at each successive temperature reached the frozen austenite has the carbon-content of the point on Aa which that temperature

**abscissa**cuts, and the still molten part or " mother-metal " has the carbon-content horizontally opposite this on the line AB.AdvertisementThe ordinate of the dotted curve which contains its "centre of gravity" has, of course, for its

**abscissa**the "mean" number of glands; the maximum ordinate of the curve is, however, at 2.98, or sensibly at 3 glands, showing what Pearson has called the "modal" number of glands, or the number occurring most frequently.Thus PS (or OR) is the

**abscissa**of P. The word appears for the first time in a Latin work written by Stefano degli Angeli (1623-1697), a professor of mathematics in Rome.The relation between x and t in any particular case may be illustrated by means of a curve constructed with I as

**abscissa**and x as ordinate.The angle cp is termed the eccentric angle, and is geometrically represented as the angle between the axis of x (the major axis of the ellipse) and the radius of a point on the auxiliary circle which has the same

**abscissa**as the point on the ellipse.In modern notation, if we denote the ordinate by y, the distance of the foot of the ordinate from the vertex (the

**abscissa**) by x, and the latus rectum by p, these relations may be expressed as 31 2 for the hyperbola.AdvertisementIf, as is usually the case, the ordinate throughout each strip of the trapezette can be expressed approximately as an algebraical function of the

**abscissa**, the application of the integral calculus gives the area of the figure.We take a fixed line OX, usually drawn horizontally; for each value of X we measure a length or

**abscissa**ON equal to x.L, and draw an ordinate NP at right angles to OX and equal to the corresponding value of y .
