ArcLengthFactor


gives the derivative of the arc length of the curve described by the parametrized curve coordinates with respect to the parameter t in the default coordinate system.

gives the derivative of the arc length of a curve in the coordinate system coordsys.
  • The parametrized curve coordinates should be given in coordsys, if specified, or the default coordinate system otherwise.
  • If the parametrized curve coordinates are not given, the default coordinate variables for coordsys are used.
  • Integrate gives the length of the arc described by from to .
