- Arc[ <Circle>, <Point M >, <Point N> ]
- the points M and N belong to the circle, returns the arc of the circle between M and N counterclockwise.
- Arc[ <Ellipse>, <Point M>, <Point N> ]
- the points M and N belong to the ellipse, returns the arc of the ellipse between M and N counterclockwise.
- 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.
