Trying to draw some simple graphics, I could not find how to change
the order in which the different graphics primitives are plotted. E.g.
if
li= line([[-1,-1],[2,2]],thickness=5)
Pt = point([1,1],pointsize=300,rgbcolor=(0,0,0))
then
(li+Pt).show()
and
(Pt+li).show()
will give the same pl
Glad to be of help. I sort of figured that maxima wouldn't make that
big of an error. Thanks for all your hard work.

I want to pickle an object in sage notebook. It took me several hours
to create the object.
When I run the python commands for pickling, it creates a file
directory
$SAGE_HOME/notebook/worksheet/1/cells/94
Question: How can I use the python's pickling feature from the
notebook?

SAGE (via Maxima) can handle some improper integrals. E.g. in the
"Constructions" documentation we see
sage: integrate(1/x^2, x, 1, infinity)
1
which does obtain. Here's one for which Maxima needs to ask a
question (in a partial fraction decomposition?), and so the
computation fails (raising a
If you get that error message, you can use assume to make it so that
Maxima does not ask the question:
sage: assume(x^2-x+1 >0)
sage: integrate(x/(1+x^3),x,1,infinity)
(6*log(2) - sqrt(3)*pi)/18 + pi/(2*sqrt(3))

Hello Rishi,
You can use the 'save' command as illustrated below.
sage: a = matrix(2, [1,2,3,-5/2])
sage: save(a, '/home/mike/a.sobj')
sage: b = load('/home/mike/a.sobj')
sage: b

[ 3 -5/2]

Dear Sage supporters,
i wrote some extension class providing fancy methods, i did some
timings for these methods, and now i'm puzzled: While the CPU times
are about constant, the wall times RAPIDLY increase when i repeat the
computation!

Understood. Is there a well-constructed Maxima guidebook which could
be linked to from one of the calculus documentation/tutorial pages?
Though presumably the SAGE syntax is more flexible.
Nonetheless, unless there is some weird assumption about complex
numbers hidden in Maxima for doing real in
