John,
I don't know either well enough to be able to answer your question.
CAS for me are mostly a hobby. Occasionally I do need to solve a hard
separation of variables problem, or a hard integral, but usually I
find a workaround, either an approximation or I change something
physical if i can to

Very exciting!
I'll have a look at your attempt, William.
In the meantime, can anyone direct me to a comparison between REDUCE

This should help:

but the download link there is broken). Also, you can

I've not tested that though.

What is the functionality in REDUCE which you need which is not
already provided in Sage? My impression is that REDUCE is a rather
old package which has not been actively developed for some time
(though I may well be wrong -- I last used it in the 1980s).

Typically one uses the parent() function wh

sage: ?parent
Type: function
Return x.parent() if defined, or type(x) if not.
I wonder why this is a function, and not a method of Parent? (Am I right that
all Sage parents inherit from Parent? Would be great to know this)

Ah, right, sorry about that. So the points are in the right place,

500 is not the number of contours but the *precision*.

It appears this is caused somehow by implicit_plot; if I use
parametric_plot for the ellipse everything works normally.

I am trying to do a demo for a class and I have encountered a strange
and very annoying error (or I am missing something).
If I do:
{{{
var('x,y')
f = (x^2+y^2)^(.5)
cp = contour_plot(f,(-3,3),(-4,4), fill=False, plot_points = 80, cmap

This could be greatly sped up by changing
maxima.assume('...')
to
maxima.eval("assume(..)")
in the calculus code...
sage: timeit("maxima.eval('assume(x>0)')")
5 loops, best of 3: 53.2 ms per loop
sage: timeit("maxima.assume(x>0)")
5 loops, best of 3: 122 ms per loop

Dear all,
Is there a reason why the assume(...) command takes so much longer
than var(...)?
Example:
%time
var('av jbiom lwat p rwat veloc mort epot esv etv esb etb wv wb qbv
bv')
gives:
CPU time: 0.00 s, Wall time: 0.00 s
On the other hand,
%time
assume(p>0, veloc>0,
mort>0,lwat>0,jbiom>0,rwat>

Hi, try this:
sage: P. = PolynomialRing(QQ)
sage: matrix(P,4,4,((a, b, 0, 0),
: (b,-a,b,0),
: (0,b,a,b),

[ a b 0 0]
[ b -a b 0]
[ 0 b a b]
[ 0 0 b -a]
sage: A
Hi,
How can I diagonalize a matrix in the with symbolic values?
The matrix has the form of:
((a, b, 0, 0),
(b,-a,b,0),
(0,b,a,b),
(0,0,b,-a))

Hello Martin,
Thank you very much for your reply. As you suggested, I computed the
lexicographical Gröbner basis of the ideal generated by the
polynomials e. It is:
G = [x15 + x111 + 1, x20 + x111, x21 + x111, x28 + x111 + 1, x29 +
x111 + 1, x31 + x111, x39, x46, x47 + x111, x63 + 1, x79 + x111
Am I doing something wrong in the session below?
I admit that I do not understand python types and methods yet. When
can I apply the functional notation, when the method notation? It
seems that it's not a language thing, because they often return
different things. As another example, Mod(5,3)
Sorry, I forgot that there is already a trac ticket on this (#4217). I

gives a nicely formatted output with line breaks

I have experience with Xen.
Can set up a virtual machine for Sage.
It's not that difficult anyway.

Dear all,
I just installed sage 3.1.3.rc0 and the problem about losing the html
formatting in notebook cells is still there. Does anyone have an idea
how to fix this? Isn't anyone else annoyed by this?? Or am I doing
something wrong?
Thanks again for your help!
