Examples

  • But if one grants, as Leibniz does, that that there is an infinitesimal straight stretch of the curve (a side, that is, of an infinilateral polygon coinciding with the curve) between abscissae 0 and e, say, which does not reduce to a single point then e cannot be equated to 0 and yet the above argument shows that e2 = 0.

    Continuity and Infinitesimals

  • Now Leibniz could retort that that this argument depends crucially on the assumption that the portion of the curve between abscissae 0 and dx is indeed straight.

  • It is a paper you cannot make head nor tail of, and at the end come five or six long folded diagrams that open out and show peculiar zigzag tracings, flashes of lightning overdone, or sinuous inexplicable things called “smoothed curves” set up on ordinates and rooting in abscissae — and things like that.

  • If from the diagram, Fig. 1, we plot a curve the abscissae of which represent exciting current, and the ordinates magnetic moment of the soft iron core, we find that a considerable portion of the curve is almost a straight and only slightly inclined line.

  • Deviations being proportionate to abscissae, and measured solar energies to ordinates, we have here (1) the distribution of energy in the prismatic, and (2) its distribution in the normal spectrum.

  • The abscissae represent intervals of time, the ordinates the measured lengths of the growing filament.

  • The abscissae, or horizontal distances, are temperatures in degrees Fahrenheit from 30 degrees below zero, at the left, to 220 degrees above, at the right.

  • Fig. 4 shows two curves; the one drawn in a full line is obtained by plotting the deflection in degrees of the needle of a potential indicator as abscissae, and the corresponding electromotive forces measured simultaneously on a standard instrument as ordinates; the dotted line shows what this curve would be with an ordinary tangent galvanometer.

  • The speeds are plotted as abscissae, and the electrical work absorbed in watts divided by 746 as ordinates; then with a series-wound motor we obtain the curve, EE.

  • To find these speeds we load the brake to different weights, and plot the resulting speeds and horse powers as abscissae and ordinates producing the curve, BB.
