I'm trying to find the solutions to solve this equation
sage: a=8594.0*x^3 - 30768.0 *x^2 + 36399.0 *x -14224.0
sage: b=solve(a==0,x)
sage: for i in b:
: c=i.rhs()
: print c.n()
:
1.19783952189420 - 4.16333634234434e-17*I
0.998467807920659 + 1.38777878078145e-17*I
1.3838648833
well, Mathematica probably does a counting of real roots before
solving
(and in any event an equation of odd degree with real coefficients is
guaranteed to get at least one
real solution).
It could also be that it just does a more aggressive rounding than
Sage.
In any event you can do this rounding

Hi all,
This is just a short notice to say that I've uploaded (a while back) a
patch for support of differential forms to Sage, see:
http://trac.sagemath.org/sage_trac/ticket/9650
Symbolic computations with tensors etc. have come up a number of times
on this mailing list, so I thought maybe
A general "physics" module would be nice too, we could put some other
things there once we are satisfied with units. In particular, I'd like
to see physical constants. So far i cannot get sage to render plank's
reduced constant as hbar.
Cheers!
Oscar.
