# Sector Command

From GeoGebra Manual

- 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.
