Are you sure that SymPy's behaviour is well-defined? In [1]: z = Symbol('z', imaginary=True) In [2]: z.is_imaginary Out[2]: True In [3]: z.is_real Out[3]: False In [4]: limit(1/z, z, 0) Out[4]: ∞ In [5]: type(_) Out[5]: sympy.core.numbers.Infinity -- You received this message because you

[sympy] Gitter supports KaTeX

Not sure if people know this but Gitter seems to support KaTeX so you can type a subset of math on Gitter, which is a very nice feature for us. Jason moorepants.info +01 530-601-9791 -- Forwarded message -- From: Mike @GitterHQ mike.gitte...@gitter-2.mail.intercom.io Date: Fri,

My guess is that limit() doesn't look at assumptions. Also, limit uses real limits, not complex limits (which are much harder to work with algorithmically). The oo**zoo thing is a bug. Please open an issue in the issue tracker about it. Aaron Meurer On Mon, Jun 8, 2015 at 1:10 PM, Francesco

[sympy] Test timeouts on Travis CI after merging 2508

2015-06-08 Thread Sudhanshu Mishra
Hi all, Slow tests are getting errored very frequently because of timeout. I think this is happening because of https://github.com/sympy/sympy/pull/2508. We'll improve performance of this code eventually, but we need to figure out an immediate solution so that development goes smooth. We can do

[sympy] Indexed symbols in simultaneous equation

2015-06-08 Thread TIANJIAO SUN
Hi, For expressive reasons, in some applications I name my symbols as IndexedBased, but really I want to consider U[x,y] and U[x,y-1] etc to be unrelated. I got equations of relations between bunch of such symbols, and I want to express some of them with the others, but somehow solve() doesn't
