If the cutting plane be produced so as to cut the opposite cone, another curve will be formed, which is also an hyperbola. Both curves are regarded as branches of the same hyperbola.

We seldom, it is true, get proof positive, as in the case of the Dermodys, father and son, that they will no more return. Generally their doing so any day may be supposed ... — Strangers at Lisconnel • Barlow Jane Read full book for free!

It is said that he was the first to introduce the words ellipse and hyperbola. So late as the eleventh century his complete works were extant in Arabic. Modern geometers describe him as handling his subjects with less power than his great predecessor Archimedes, but nevertheless displaying extreme precision ... — History of the Intellectual Development of Europe, Volume I (of 2) - Revised Edition • John William Draper Read full book for free!
