Comment(by robert.marik):
Replying to [comment:9 mvngu]:
> With the new Maxima spkg and the patch `trac_7325-final.patch`, I got
these failures:
This follows probably from updated version of fourier elimination in
Maxima. The answers are correct and equivalent to previous answers. I
think that it is sufficient to fix the tests and to fix the following
message from solve command
{{{
NotImplementedError: solving only implemented for equalities
}}}
I'll update the patches after testing on 4.3.rc1
what about to replace output of
{{{
solve_ineq(x^2>-1)
}}}
from
{{{
'all'
}}}
to
{{{
x>-Infinity
}}}
?
