piecewise functions => [with patch; needs work]
Indefinite integration for piecewise functions
Comment:
I am seeing two doctests failure:
{{{
sage -t -long "devel/doc/const/const.tex"
**********************************************************************
File "/scratch/mabshoff/sage-3.3.alpha3/devel/doc/const/const.tex", line
525:
: f.integral()
Expected:
3
Got:
Piecewise defined function with 2 parts, [[(0, 1), x^3/3], [(1, 2),
(15*x - x^3)/3 - 13/3]]
**********************************************************************
}}}
and
{{{
sage -t -long "devel/sage/sage/calculus/wester.py"
**********************************************************************
File
"/scratch/mabshoff/sage-3.3.alpha3/devel/sage/sage/calculus/wester.py",
line 454:
: f.integral()
Expected:
100
Got:
Piecewise defined function with 2 parts, [[(-10, 0), 50 - x^2/2], [(0,
10), x^2/2 + 50]]
**********************************************************************
}}}
If someone posts additional patches please also fold the patches together.
Cheers,
Michael
