Comment #7 on issue 2953 by [email protected]: Limits of Meijerg
http://code.google.com/p/sympy/issues/detail?id=2953
At least for this example the result now makes sense:
In [17]: G
Out[17]: meijerg(((), ()), ((1,), (0,)), -x)
In [18]: limit(G, x, 0)
Out[18]: meijerg(((), ()), ((1,), (0,)), 0)
In [19]: hyperexpand(_)
Out[19]: 0
For the other limit we get a graceful failure in the series module:
In [25]: limit(g, x, oo)
[...]
PoleError: Don't know how to calculate the limit(sqrt(1/x)*besseli(1,
2*sqrt(1/x)), x, 0, dir=+), sorry.
In [26]: gruntz(g, x, oo)
[...]
PoleError: Asymptotic expansion of besseli around [1, oo] is not
implemented.
That is ok so far.
