Hi guys,
This is so simple that probably someone else has already noticed it, but
just in case:
sage: x,t = var('x,t')
sage: f = (1-x)/(1-x*cos(t))
sage: f(x=1)
0
sage: f(t=0)(x=1)
1
The second one is, of course, the correct answer. (FYI, Mathematica9 fails,
too.)

My guess is that this is more of a convention than anything else.

Thanks for the answer, kcrisman!

If Mma and Maple do it too, that would be my guess. In any case, it is
'known' and I bet you'll find other examples with a search of the email
lists (though searching for
The expression y = (1-x)/(1-x*cos(t)) is, as given, undefined whenever
x*cos(t)=1, for example at (x,t)=(1,0).
When x=1 it simplifies to 0/(1-cos(t)), which equals 0 except where
cos(t)=1 where it is undefined but has a limiting value of 0.
When t=0 it simplfies to (1-x)/(1-x), which equals 1
Could you push me in the right direction? Would Django be a good tool to
accomplish this with?

Your top-post makes it a little difficult to determine what with is. Do
you mean communicating with a notebook server? In that case,
I agree that using the notebook is probably a bad idea. Have you tried
using sage's -c flag? according to the command line help -c cmd --
Evaluates cmd as sage code. In addition if you are using python you could
use the subprocess module. I'm thinking something like:
