- 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.
