The call GetRootPoint(v) returns the root point, as a free Vector, of the vector space to which the rooted Vector v belongs.

The Student[VectorCalculus] package uses the same Vector data structures as the VectorCalculus package. For more information about the different types of Vectors, see VectorCalculus,Details.
