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