I just wanted to second this problem. When I run a Maple command in
the Sage Notebook (Sage 3.1.2 on OSX 10.4), I have to execute the cell
three times to see the output. The first time I execute, I get no
output at all. The second time, I get an output that's something like

Hi All,
I have successfully compiled the new
quantlib_swig-0.9.6
quantlib-0.9.6
packages from Sage 3.0.1.
A number of functions work fine form the Sage notebook.
Unfortunately the important quantlib Date() function is causing
problems.
I am trying to run
from QuantLib import *

Sorry, when I read the first lines of that page I thought I had to re-

Thanks for the advice! It seems like a combination of expand() and
simplify() would go a long way. Unfortunately, I am not a
Mathematician and hence struggle to understand rings and fields.
I am still a bit hesitant about simplify, though. Should a bug report
be filed to Maxima? By the way, is py

That's interesting. It seems that the bug lies in the use of floating
point numbers? By the way, simplify_trig and simplify_rational create
the same mistake. I agree that the use of simplify_radical() is not
very useful here, but if it makes such an obvious mistake, how
confident can we be that it
A variation on your first try is:
sage: ((a*b - (1/2)*a*(b - c))/a).simplify_radical()
(c + b)/2
which works fine. Maybe it's a bug in maxima. I don't see why you
would need simplify_radical() at all here, since your expression
contains no radicals.

Should that be:
gauss(x) = exp(-(x)^2/(2*sigma^2))
sometimes my copy and paste strip the "^" signs; is that what happened?

Yes, confirmed. I now just use the computer name because it is a lot
easier to remember. :)
Is there an easy way to prevent someone from accidentally deleting data
on the computer? Just login from a restricted account before opening the
notebook, or do I have to set up a chroot jail?
Thanks!
Is "gauss(x) = exp(-(x)2/(2*sigma2))" a typo? Because that raises a
syntax error for me.

Here's the code:
sigma = 0.2
gauss(x) = exp(-(x)2/(2*sigma2))
gauss1 = gauss(x).derivative
gauss2 = gauss1(x).derivative
ngauss2(x) = -1*gauss2(x)
sngauss2(x,y) = ngauss2(sqrt(x2 + y2))
a1 = var('a1'); a2 = var('a2'); b1 = var('b1'); b2 = var('b2')
chunkx = integral(sngauss2, x, a1, b1)
