(self, otherframe, variables=False)
return express(self, otherframe, variables=variables)
Returns a Vector equivalent to this one, expressed in otherframe.
        Uses the global express method.

        Parameters
        ==========

        otherframe : ReferenceFrame
            The frame for this Vector to be described in

        variables : boolean
            If True, the coordinate symbols(if present) in this Vector
            are re-expressed in terms otherframe

        Examples
        ========

        >>> from sympy.physics.vector import ReferenceFrame, Vector, dynamicsymbols
        >>> q1 = dynamicsymbols('q1')
        >>> N = ReferenceFrame('N')
        >>> A = N.orientnew('A', 'Axis', [q1, N.y])
        >>> A.x.express(N)
        cos(q1)*N.x - sin(q1)*N.z
Returns a Vector equivalent to this one, expressed in otherframe.
        Uses the global express method.
