Hi,
Using Sage, I am missing a feature of Magma command line interface. In
Magma, if I enter a line found in history using up arrow key, and then
press down arrow key, then the next line in history is fetched. This
feature allows me to fetch as many successive lines in history as
like. Does Sage(

At my institution we are thinking of using Sage in our teaching. We
would like to install it on a server, so that the students may use it,
either from home or from the computer labs at the university during
programmed activities. My question is the following: what are the

Hi there,
I have a problem when doing some inheritance from class
SymbolicArithmetic in sage from version 3.4 and up. There is no
problem with 3.3. Here is a sample code :
in file classtest.sage put :
class test(SymbolicArithmetic):
def __init__(self,eq):

sorry for posting all my problems here I still have no good tutorial
and the error messages are not very helpful...
The whole error message I get is below. The program I am using is not
very complicated. It is a python script which calls different

My knowledge of jquery is currently rudimentary (glanced at a book

Hi,
I have some equations that use the Greek letter lambda in them, but
I'm having problems because lambda is a keyword in python, and at some
points the two collide. For example:
sage: l = var("lambda")
sage: t = var("theta")
sage: e1 = t == l^2
sage: e2 = e1.solve(l)
sage: e1
theta == lambda^2

I've built several recent versions of Sage on the same box (a 64-bit

Martin,
Thanks for the reply. Did I mention I'm using 3.4.2? When I try
using mon // x instead of mon / x, I get an exception:

Bonsoir M.

There's a new spkg at http://trac.sagemath.org/sage_trac/ticket/5218
that needs to be reviewed. It's the same as the old one except that
it has a fix for

I thought http://trac.sagemath.org/sage_trac/ticket/2740 made it

I'm not exactly sure what that is. I opened the terminal, typed sage

I found that the error occurs only if I take r = float. In the case if
r = int I can get an expression but I can't convert in using .n()

In order to carry out manipulations, Maxima changes all floats to
rationals.
You can suppress the messages, I forget which flag it is,
but probably it's better to avoid floats until you really need them.
