| Long-period comets can have orbits ranging from eccentric ellipses to parabolas to even modest hyperbolas. |
| Very few listened to the monotonous drone of the teacher as he explained proofs and parabolas. |
| The ejecta blanket hits at a parabolic shape, similar in appearance to the dark parabolas seen around impact craters on Venus. |
| He also discussed parabolas, angle trisection and magic squares. |
| Now, gentlemen cosines, will you cease to throw parabolas and hyperbolas at each other's heads? |
| There are many topics covered in the book including a study of circles, triangles, geometric series, ellipses, parabolas and hyperbolas. |
