Arc Command
From GeoGebra Manual
- Arc[Conic, Point A, Point B]
- Returns a conic section arc between two points A and B on the circle or ellipse c. For other conics is the result undefined.
- Arc[Conic, Number t1, Number t2]
- Returns a conic section arc between two parameter values t1 and t2 on the circle or ellipse. For other conics is the result undefined.
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.
