(self, frame1, frame2=None)
return express(self, frame1, frame2)
Expresses this Dyadic in alternate frame(s)

        The first frame is the list side expression, the second frame is the
        right side; if Dyadic is in form A.x|B.y, you can express it in two
        different frames. If no second frame is given, the Dyadic is
        expressed in only one frame.

        Calls the global express function

        Parameters
        ==========

        frame1 : ReferenceFrame
            The frame to express the left side of the Dyadic in
        frame2 : ReferenceFrame
            If provided, the frame to express the right side of the Dyadic in

        Examples
        ========

        >>> from sympy.physics.vector import ReferenceFrame, outer, dynamicsymbols
        >>> N = ReferenceFrame('N')
        >>> q = dynamicsymbols('q')
        >>> B = N.orientnew('B', 'Axis', [q, N.z])
        >>> d = outer(N.x, N.x)
        >>> d.express(B, N)
        cos(q)*(B.x|N.x) - sin(q)*(B.y|N.x)
Expresses this Dyadic in alternate frame(s)
