Recent changes to 355: Warning for non-polynomial algsyshttps://sourceforge.net/p/maxima/bugs/355/2003-07-12T03:22:11ZWarning for non-polynomial algsys2003-07-12T03:22:11Z2003-07-12T03:22:11ZStavros Macrakishttps://sourceforge.net/u/macrakis/https://sourceforge.netb1bdb394b8550ad1482d7adfc27835ae691b51bcSolve for multiple variables calls Algsys. As it says
\(clearly\!\) in the documentation, this only works for
polynomial equations.
It would be useful, I think, if we would give a warning
\(or an error?\) when a non-polynomial equation were
passed to algsys, e.g.
\(C1\) solve\(sqrt\(a^2+b^2\)=0,\[a,b\]\)
Warning: Solve/Algsys can only solve for multiple
variables when the equations are polynomial. The
equation sqrt\(a^2+b^2\)=0 is not polynomial.
\(D1\) \[\]
This is a common beginner's error, I think, encouraged of
course by the fact that the command is called &quot;solve&quot; --
you'd think it could solve any simple equation....
