41. This proof proves the theorem for circle and then generalizes it to conics . 42. The value of e controls what kind of conic section the orbit is. 43. In fact each such quadric contains the Veronese surface, which parametrizes the conics 44. However, any two conic sections are projectively equivalent. 45. The Albers equal-area conic projection features no distortion along standard parallels. 46. The deep dark brown cones are pendulous and ovoid-conic in shape. 47. The spire short, conic , very small compared with the body whorl. 48. Surprising that neither parabola nor conic section gives this. 49. Represents a conic in the pencil determined by and. 50. This technique also uses a hand sensor to adjust the conic pointer size.
