Comment (by christiankuper):
Hello Andrew,
sorry for the long silence but now finally I find time to look into your
patch. Running the doctest I currently get one failure:
{{{
**********************************************************************
File "/opt/sage-dev3/devel/sage-main/sage/functions/piecewise.py", line
501:
sage: f.trapezoid(4)
Expected:
Piecewise defined function with 4 parts, [[(0, 1/2), 1/2*y], [(1/2,
1), 9/2*y - 2], [(1, 3/2), 1/2*y + 2], [(3/2, 2), -7/2*y + 8]]
Got:
Piecewise defined function with 4 parts, [[(0, 1/2), 1/2*x], [(1/2,
1), 9/2*x - 2], [(1, 3/2), 1/2*x + 2], [(3/2, 2), -7/2*x + 8]]
**********************************************************************
}}}
I am not sure why this is happening but will try to look into it.
Christian
