# Sector Command

From GeoGebra Manual

- Sector[Conic, Point A, Point B]
- Yields a conic section 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 section 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.

- Circle:
