 GetRootPoint
 returns the root point of rooted Vector

 Calling Sequence GetRootPoint(v)

Parameters

 v - Vector; a rooted Vector

Description

 • 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.

Examples

 > $\mathrm{with}\left(\mathrm{Student}\left[\mathrm{VectorCalculus}\right]\right):$
 > $\mathrm{vs}≔\mathrm{VectorSpace}\left(\mathrm{cartesian}\left[x,y\right],\left[a,b\right]\right):$
 > $v≔\mathrm{vs}:-\mathrm{Vector}\left(\left[c,d\right]\right):$
 > $\mathrm{GetRootPoint}\left(v\right)$
