Here the road was dry and only a few cars passed him before he drifted past a private hot spring, along the wide curve and by the County fairgrounds before entering Ridgway.
From any point without the curve two, and only two, tangents can be drawn; if OP, OP' be two tangents from 0, and S, S' the foci, then the angles OSP, OSP' are equal and also SOP, S'OP'.
He announced that the curve required in the first problem must be a cycloid, and he gave a method of determining it.
The cycloid was a famous curve in those days; it had been discussed by Galileo, Descartes, Fermat, Roberval and Torricelli, who had in turn exhausted their skill upon it.
FOLIUM, in mathematics, a curve invented and discussed by Rene Descartes.
Y, hence DC is the half of OC, proving the curve to be a parabola.
He began first a short ascent, then a drop to a sharp curve he nearly missed, causing him to reduce his speed further.
In such a curve the percentage composition can be plotted horizontally and the temperature of the freezing-point vertically, as in fig.
