For some reason machine thinks that I am trying to add a matrix to an equal sign.

Is it italic when copied and pasted?  Is it bold when copied from maple 8?  I just ahve not been able to work it out.

The only way that I can think of doing it is by multiplying by a tetrad.  Even then it does not work well see my worksheet:  The Dirac Equation in Robertson-Walker spacetime.

Hope that no one minds a beginners question.   How do I enter non-null k=0 robertson-walker tetrad in the physics package?  Not the tensor package as that has depreciated or the differential geometry package as notation is different there.
