(self, frame)
return time_derivative(self, frame)
Take the time derivative of this Dyadic in a frame.

        This function calls the global time_derivative method

        Parameters
        ==========

        frame : ReferenceFrame
            The frame to take the time derivative 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.dt(B)
        - q'*(N.y|N.x) - q'*(N.x|N.y)
Take the time derivative of this Dyadic in a frame.
