But my point is that the string passed is nearly identical to the Sage
command, i.e.
sage: solve(x^2-1,x)
becomes
(%i1) solve(x^2-1,x);
Of course this gets a little more complicated with to_poly_solve and
the multi-equation solve, but not much more complicated (I think we
have to send the variables to solve for in the multi-equation version
as a list-like string "[x,y]", for instance).
I'm not sure what we should do in terms of spurious solutions. It's
hard to check for all of them... and checking for zero, as rjf will
undoubtedly remind us, is not always possible to decide. Probably
better is for several of us to start understanding the internals of
Maxima a little better - especially if we can get library access, as
some threads and tickets have suggested - and starting to help fix
those bugs!
