Student[VectorCalculus][Curvature] - compute the curvature of a curve
Calling Sequence
Curvature(C, t)
Parameters
C
-
free or position Vector or Vector-valued procedure; specify the components of the curve
t
(optional) name; specify the parameter of the curve
Description
The Curvature(C, t) calling sequence computes the curvature of the curve C.
The curve C can be specified as a free or position Vector or a Vector-valued procedure. This determines the returned object type.
If t is not specified, the function tries to determine a suitable variable name by using the components of C. To do this, it checks all of the indeterminates of type name in the components of C and removes the ones that are determined to be constants.
If the resulting set has a single entry, that single entry is the variable name. If it has more than one entry, an error is raised.
If a coordinate system attribute is specified on C, it is interpreted in this coordinate system. Otherwise, the curve is interpreted as a curve in the current default coordinate system. If the curve and the coordinate system are incompatible, an error is returned.
