Hi, What did you expect? The function 1/x^2 is not integrable at 0. The following (convergent) integrals does work
sage: integral(1/x^2, (x, 1, +oo)) 1 sage: integral(1/x^2, (x, -oo, -1)) 1 The following (divergent) integral produces the same result sage: integral(1/x^2, (x, -1, 1)) Traceback (most recent call last): ... ValueError: Integral is divergent. Note that this kind of questions is better directed to either https://ask.sagemath.org or https://groups.google.com/g/sage-support.
