- Arc[ <Circle>, <Point>, <Point> ]
- Returns a circle section arc between two points on a circle.

- Arc[ <Ellipse>, <Point>, <Point> ]
- Returns a conic section arc between two points on an ellipse.

- Arc[ <Circle>, <Parameter Value>, <Parameter Value> ]
- Returns a circle section arc between two parameter values on a circle.
**Note:**Internally the following parametric forms are used:

Circle: (*r*cos(*t*),*r*sin(*t*)) where*r*is the circle's radius.

- Arc[ <Ellipse>, <Parameter Value>, <Parameter Value> ]
- Returns a conic section arc between two parameter values on an ellipse.
**Note:**Internally the following parametric forms are used:

Ellipse: (*a*cos(*t*),*b*sin(*t*)) where*a*and*b*are the lengths of the semimajor and semiminor axes.
