“If the planes pass through the vertex of the cone, the conics are said to be degenerate, otherwise they are not.”

“It deals with normals to conics regarded as maximum and minimum straight lines drawn from particular points to the curve.”

“His work in geometry included a study of conics, quadrics and projective geometry.”

“Tire uniformity measurement specifications include radial and lateral force variation, harmonics, conicity and runout, to name a few.”

“This is confirmed by the experimental data, presented in, which indicates that the resultant effect of the conicity of the crucible on the movement of the melt is not strong.”
