| It's the other conic sections that confuse me, like ellipses and hyperbolas. |
| In book two Apollonius investigates how hyperbolas are related to their asymptotes, and he also studies how to draw tangents to given conics. |
| Long-period comets can have orbits ranging from eccentric ellipses to parabolas to even modest hyperbolas. |
| A family of hyperbolas as shown in the figure may be printed on a chart. |
| Angeli's many works were on infinitesimals and he used them to study spirals, parabolas and hyperbolas. |
| The intersections of the surface with planes parallel to the xz and yz planes are hyperbolas. |
