Dear all
I installed jsmath image fonts in fresh 4.4.2, but these fonts remain
unavailable - the switch to these fonts is still inactive. Does
anybody have the same issue? Is it a bug in my configuration, or a bug
in sage? Many thanks and have a nice weekend.

Tnx Robert,
I rewrote the routine somewhat to use less stored values. Still I got
the following message:

I have not been able to get the following behaviour out of maxima
directly, but the following code illustrates that maxima's solve

Here is what is happening (certainly a bug). In the code which picks
a random element from F, F is treated as a sequence and then
subscripted with a random subscript. But (as you can verify)
evaluating F[0] or F[1] raises an error, since the __getitem__ method
of a field is used to create

Does the function is_FreeModule() do what you want by any chance?

And if it does and you don't want to see the deprecation warnings all
the time:

John, Thanks for the explanation. It would have never occurred to me
that polynomial rings would have gotten involved here.

Hi all,
I was wondering if there is any support in sagemath to define new
variables that are derivatives or integrals of existing variables. for
instance, suppose that i define a variable called theta , is it now
possible to define omega that is omega=thetal.derivative(t). This
problem occured

If you look at the traceback message, you can see that what it was

Thank you very much!
That has worked!

Hi all,
i've used d1,d2 as variables in symbolic equation. Solving this
equation returns some unexpected (at least for me) results. Simplest
case:
x,d1=var('x,d1'); solve(x^2-d1==0, x)
returns
[x == -sqrt(factorial(k + 2*n - 1)/factorial(2*k + 4*n)), x ==
sqrt(factorial(k + 2*n -

This happens only with d1 and d2. a1 or what ever works well.
d2 has special meaning in Maxima and the solve() command uses Maxima
for its backend. This is the same problem as reported at this [1]

The source code for Integer.sqrt() calls some lower level stuff that
I'm not familiar with, otherwise I'd try to fix it. Should I submit a
bug report? Can I even do that?
