integral(1/x^2, x, -infinity, -1, algorithm='sympy')
Unfortunately, I got:
Traceback (click to the left of this block for traceback)

AttributeError: 'MinusInfinity' object has no attribute '_sympy_'
What's going wrong?Green diodSat, 21 Jan 2012 19:00:39 +0100https://ask.sagemath.org/question/8653/
