circular cone surface

The rotation surface formed by a straight line diagonally intersecting the generatrix and the rotation axis

Conical surface, when the generatrix and Rotation axis The rotation surface formed by an oblique straight line, the equation is z=± (√ x left 2+y left 2) × cot α。

Chinese name: circular cone surface

equation: z=±（√x＾2+y＾2）× cot α
Vertex of cone face: Intersection of bus and axis

definition

In a cone, the intersection of the generatrix and the axis is called the vertex of the cone

circular cone surface equation ：z=±（√x＾2+y＾2）× cot α

Where α is the conical surface Semiapex angle

x＾2/a＾2+y＾2/a＾2=z＾2

Where, a=cot α
