Parameters ========== other : Point/CoordSys3D If other is a Point, the position of this Point wrt it is returned. If its an instance of CoordSyRect, the position wrt its origin is returned. Examples ======== >>> from sympy.vector import CoordSys3D >>> N = CoordSys3D('N') >>> p1 = N.origin.locate_new('p1', 10 * N.i) >>> N.origin.position_wrt(p1) (-10)*N.i zis not a Point or CoordSys3D) r r rrr originrzerorrrrangelen)selfother rootindexpathresultis r position_wrtzPoint.position_wrt+s@25%(( <uj11 <CJJ:;<< < eZ ( ( !LE D= #;  dl " #9  ]d " # ?
