Now I want to test an expression with the binomial function call.
y = binomial (3*x, x)# is fine
op = y.operator() # is also fine
Why is there a () here, but not in the previou
Hi,
Mike Hansen and I were testing a new database server [1] unrelated to
trac, and got something slightly wrong
in the apache config. It's fixed now. Thanks for reporting.

Whatever ticket I pick, I get the error message
"Not Found
The requested URL was not found on the server.
If you entered the URL manually please check your spelling and try again."

Hello,
I play with expressions, and transform sin(x) to (exp(i*x)-exp(-i*x))/2.
So I use a lot of test as
var ('x')
y = cos(x) # or any other expression"
op = y.operator # so op == cos
if op == cos : ... # this test is fine, not the next one
else : ...
Now I want to test an expression

Those commands work for me on linux (ubuntu 9.10, intel i7 860) and OS
X 10.6. Maybe you could run all the standard tests for sage (sage -t
$SAGE_ROOT/devel/sage/sage), that might help narrow the problem down.

I would suggest to run sage with valgrind to get more information out
of your error messages.

Hi,
You can try Burcin patch which restores GiNaC original ordering and

You can *then* apply mine based on Burcin one to get a better (??)
