I haven't looked over this carefully yet, but I did
look over the previous version you did for "Mike's function",
which I thought was really neat. Incidentally, the general
case might need to be separated into subcases, according as
to whether certain expressions that show up in a denominator
are zero. For the expression above, we would assume of course
that neither a nor d is zero, but bd - ac might be zero.
However, these kinds of "finishing touches" shouldn't be
very difficult to incoporate into what you've already done.
