Taxman,
Thanks for the report. Current behavior is to support latex versions
of graphs by adding two "\usepackage" commands to the preamble. It is
possible tkz-arith.sty should also be added, and maybe something
bigger like tikz and pgf.
Also, the documentation could perhaps be improved b

Hi everyone,
I thought I'd share the following:
sage: assume(x>0)
sage: solve([x^2-1],x)
[x == -1, x == 1]
Shouldn't it not give me the negative solution? Also:
sage: assume(x == 1)
sage: bool(x == 1)
False

You could also make your own sub-class like:
class mylist(list):
def sum(self):
return sum(self)
but then you would have to explicitly cast things to this class.

the int->integer replacement is done by a preparser. if you turn it
off, sage is "pure" python only.
the list is a pure python object and i don't think it makes sense to
change anything. I recommend you to use a "vector",
sage: vector(RDF, [1,2,3])

Hi,
I noticed that the int python type is replaced by the Integer type in
Sage. I'm wondering if I could do the same with the list type, so I
can add a functionality I need to it.
Could you tell how I can do it?
Thanks,
Carlos
