Comment #18 on issue 1823 by [email protected]: integral.atoms(Symbol)
should introspect
http://code.google.com/p/sympy/issues/detail?id=1823
Yes, we need a unified approach for boundaries.
We have function and variables now, and this commit adds symbols:
>>> i=Integral(x+3, (x, 1, y))
>>> i.function
3 + x
>>> i.variables # the integration variables
[x]
>>> i.symbols
set([y])
And atoms gives youeverything everywhere:
>>> i.atoms()
set([1, y, x, 3])
So can this go back to PassedReview?
