Sector[Conic, Point A, Point B]
Yields a conic sector between two points A and B on the conic section.
Note: This works only for a circle or ellipse.
Sector[Conic, Number t1, Number t2]
Yields a conic sector between two parameter values t1 and t2 on the conic section.
Note: Internally the following parametric forms are used:
  • Circle: (r cos(t), r sin(t)) where r is the circle's radius.
  • Ellipse: (a cos(t), b sin(t)) where a and b are the lengths of the semimajor and semiminor axes.
