Comment #2 on issue 2856 by asmeu...@gmail.com: limit(x**16/(x**16 + 1), x,
oo) fails
http://code.google.com/p/sympy/issues/detail?id=2856
Apparently there's a hard-coded limit for the number of terms of a series
somewhere in the Gruntz limit algorithm, and it was recently bumped from 8
to 16.
It depends on how easy you want to start. There are easier bugs to work on
(search for EasyToFix in the tracker), but this one should be doable. To
solve this one, I guess we need some way to dynamically compute the number
of terms in a series. Also, we could probably implement a really simple
heuristic for computing the limit of a rational function at infinity.
If you're interested, look at the comments in gruntz.py, and look at
Gruntz's thesis.
