[sage-support] strange behavior with sums
I'm using Sage 6.2 on Arch Linux. I have posted before about sums being
wrong
https://groups.google.com/d/msg/sage-support/IgC78rcdO7c/qTWzpA9f-P8J,
and I am happy to see that the community took action. Thanks! I have been
seeing other errors that may or may not be related to those addressed in
the link above.
I open a new Sage session (command line). The following code ought to
return (e^x - 1)/x.
sage: k = var('k')
sage: sum(x^k/factorial(k+1),k,0,oo)
1/4*sqrt(pi)*sqrt(x)*e^(1/2*x)
This looks similar to the sort of nonsense it was spitting out when
misinterpreting
Bessel functions from Maxima http://trac.sagemath.org/ticket/16224. In
the same session, if I run the summation command again, the result is
different.
sage: sum(x^k/factorial(k+1),k,0,oo)
sum(x^k/factorial(k + 1), k, 0, +Infinity)
And after this it will not simplify any sums, even ones it would have done
correctly on the first try:
sage: sum(x^k/factorial(k),k,0,oo)
sum(x^k/factorial(k), k, 0, +Infinity)
Even a reset doesn't help. (As a side-note, the exit command doesn't
survive reset.)
sage: reset()
sage: k = var('k')
sage: sum(x^k/factorial(k),k,0,oo)
sum(x^k/factorial(k), k, 0, +Infinity)
sage: exit
---
NameError Traceback (most recent call
last)
/opt/sage/local/lib/python2.7/site-packages/sage/all_cmdline.py in
module()
1 exit
NameError: name 'exit' is not defined
Finite sums seem to be ok.
sage: sum(x^k,k,0,3)
x^3 + x^2 + x + 1
sage: m = var('m')
sage: sum(x^k,k,0,m)
(x^(m + 1) - 1)/(x - 1)
Any help is greatly appreciated.

Thank you. It is obviously time that I learn to use git.

well, this is actually easy to fix, as no recompilation of Sage is
needed here: the only change is in src/sage/intefaces/maxima_lib.py

if you have Sage installed locally, know how to use git then
you can get this patch applied and then run `sage -b`.
In case you do not know anything about git, you can still get a copy
of the updated file from here:
http://git.sagemath.org/sage.git/plain/src/sage/interfaces/maxima_lib.py
oops, sorry, this will give you an only unpatched copy...
So you really need to get the patch somehow.
save it as SAGE_ROOT/src/sage/intefaces/maxima_lib.py
and then run `sage -b`.

Re: [sage-support] Re: strange behavior with sums
I have installed git and chosen my name and email address. What commands
should I run to apply this patch? I have been reading the developer manual,
but at this point I am not interested in contributing code to Sage. I just
want to apply patches.

Re: [sage-support] Re: strange behavior with sums
Thanks for your help. I ran:

fatal: Not a git repository (or any of the parent directories): .git

this is basically reviewing tickets.
Although you need a developer's access to follow typical recepies from
there. However, without the latter you are still OK.
What you can do is the following:
(from your SAGEROOT directory)
git fetch http://trac.sagemath.org/sage.git
u/pbruin/16224-maxima_to_sage
you should see something like:
From http://trac.sagemath.org/sage
* branchu/pbruin/16224-maxima_to_sage - FETCH_HEAD
Now we merge the stuff we just fetched:
git merge FETCH_HEAD
this will open up an editor to record the merge commit message; write
something there (normally it will already have some text to record).
After you saved this file you will see somthing like
Merge made by the 'recursive' strategy.
