(self, otherframe)
return outvec
Returns the angular velocity Vector of the ReferenceFrame.

        Effectively returns the Vector:
        ^N omega ^B
        which represent the angular velocity of B in N, where B is self, and
        N is otherframe.

        Parameters
        ==========

        otherframe : ReferenceFrame
            The ReferenceFrame which the angular velocity is returned in.

        Examples
        ========

        >>> from sympy.physics.vector import ReferenceFrame, Vector
        >>> N = ReferenceFrame('N')
        >>> A = ReferenceFrame('A')
        >>> V = 10 * N.x
        >>> A.set_ang_vel(N, V)
        >>> A.ang_vel_in(N)
        10*N.x
Returns the angular velocity Vector of the ReferenceFrame.
Returns the angular velocity Vector of the ReferenceFrame .
