Hello, all:
In symbolic integration document, there is an example::
sage: integrate(1/x^3,x,-1,3)
Traceback (most recent call last):
...
ValueError: Integral is divergent.
However, in maxima, it returns:
(%i1) integrate(1/x^3,x,-1,3);
Principal Value
4
(%o1) -
9
Sometimes we only care about the cauchy principal value. How to get it from
sage?
maxima version: 5.28.0
sage version: 5.2
Regards,
Mizuchi
