OBSOLETE VECTOR ANALYSIS PACKAGE SYMBOL
ArcLengthFactor
As of version 9.0, vector analysis functionality is built into Mathematica 
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.
Details
- To use
, you first need to load the Vector Analysis Package using Needs["VectorAnalysis`"]. - 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[ArcLengthFactor[{f1, f2, f3}, t], {t, t1, t2}] gives the length of the arc described by
from 
to 
.
