[sage-support] Re: wrong or nonexistent results for various infinite sums
sum(x^(3*k)/factorial(2*k),k,0,oo) I understand that Sage has limited exploitation of Maxima's hypergeometric functionality, and I suspect this is the main issue. Are there any conceivable workarounds? This actually works out of the box in the latest development release, probably with the same fix in #16224. sage: sum(x^(3*k)/factorial(2*k),k,0,oo) sqrt(pi)*x^(3/4)*sqrt(1/(pi*x^(3/2)))*cosh(x^(3/2)) sage: sum(x^(3*k)/factorial(2*k),k,0,oo).simplify_radical() cosh(x^(3/2)) -- You received this message because you are subscribed to the Google Groups sage-support group.

[sage-support] Can't import sage into Python
I have a Django project with
views.py:
#!/usr/bin/env sage -python
from django.shortcuts import render
from django.http import HttpResponse
import sys
from django.http import HttpRequest
from django.template import RequestContext, loaders
sys.path.append('/Users/Jole/Desktop/django_proj/mysite/sage/src/bin')
sys.path.append('/Users/Jole/Desktop/django_proj/mysite/sage/')
from sage.all import *
def index(request):
querystring = request.GET.get('querystring')
return HttpResponse(querystring)
As you can see I am trying to import sage as a library into my Python
document so I can do some sage computations.
Unfortunately, when I fire up my Django server on localhost, I get: No
module named sage.all
As an error message. As you can see I have already tried appending to the
path. My Python Path includes sage and I can see this on my Django page,
however my PATH is
PATH
'/Library/Frameworks/Python.framework/Versions/3.4/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/local/git/bin'
According to the Django server output. I'm not sure if this could be the
problem. Any help would be *greatly appreciated.*

[sage-support] Re: Can't import sage into Python

As you know, I've already had several useless ideas for you on another
forum :( but here is another one. Is Sage itself in your regular path? By
that I mean that in my PATH I have
/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin:/usr/texbin:/usr/texbin:/Applications/MathApps:
where the last one is where I have a symbolic link to my Sage installation.
lrwxr-xr-x 1 me admin 87 Oct 10 2013 sage -
/Users/.../Sage-5.12-OSX-64bit-10.6.app/Contents/Resources/sage/sage
I was able to successfully do what you wanted, though, with a file
#!/usr/bin/env sage -python
from sage.all import *
print permutations(5)
Now, I just executed that file as a Unix file. When you are executing
yours as a *Python* file, I get the same error as you.
$ python views.py
Traceback (most recent call last):
File views.py, line 3, in module
from sage.all import *
ImportError: No module named sage.all
Solution? I suppose either find a way to have Django execute it as a Unix
file (not Python), or just run your entire project with sage -python
instead of your system Python!
Other people who actually know what they are talking about: please respond!
