New issue 2242 by [email protected]: A general way to describe and test for
singularities is needed
http://code.google.com/p/sympy/issues/detail?id=2242
A few issues require more convenient ways to test function for
singularities.
issue 2200 limit sin(oo) )
issue 2097 the vakue of sin(oo)
issue 905 series
issue 1116 integral on the segment with singular
issue 1058 Classifying formulas
Formally, now in Sympy the `oo` has a singularity behavior in SymPy now,
And somehow is used for this aims.
Also things offered about Singularity class that allow to transit of `oo`
through e.g. `sin()` function (with morphing of infinite discontinuity
Singularity to "interval" Singularity).
Now these use-cases are shaped:
- test expression of singularity at point and detect its kind.
- find singulars on the segment
