What is "unicursal"

Unicursal \U`ni*cur"sal\, a. [Uni- + L. currere, cursum, to run.] (Geom.) That can be passed over in a single course; -- said of a curve when the co["o]rdinates of the point on the curve can be expressed as rational algebraic functions of a single parameter [theta].

Note: As [theta] varies minus infinity to plus infinity, to each value of [theta] there corresponds one, and only one, point of the curve, while to each point on the curve there corresponds one, and only one, value of [theta]. Straight lines, conic sections, curves of the third order with a nodal point, curves of the fourth order with three double points, etc., are unicursal.

a. Being composed entirely of a single continuous path or line n. An object or figure composed entirely of a single continuous path or line (e.g. a http://en.wikipedia.org/wiki/Turf%20maze)

Unicursal may refer to:

• Labyrinth - a unicursal maze
• Unicursal hexagram - a star polygon
• Eulerian path - a sequential set of edges within a graph that reach all nodes
• unicursal curve - A curve which is birationally equivalent to a line.
