| The ejecta blanket hits at a parabolic shape, similar in appearance to the dark parabolas seen around impact craters on Venus. |
| Angeli's many works were on infinitesimals and he used them to study spirals, parabolas and hyperbolas. |
| She rapped the ruler even harder on my desk and returned to the blackboard and continued talking about parabolas. |
| Long-period comets can have orbits ranging from eccentric ellipses to parabolas to even modest hyperbolas. |
| There are many topics covered in the book including a study of circles, triangles, geometric series, ellipses, parabolas and hyperbolas. |
| Very few listened to the monotonous drone of the teacher as he explained proofs and parabolas. |
