I'm trying to compute the integral:
>integral(log(cot(x)-1),x,0,pi/4)
Sage (with version 5.4 and previous ones) tell that the integral is $-\infty$. But the integral converges, and it is is equal to $\frac{\pi\log(2)}8$.
I think this can be a bug. Maybe it is a Maxima issue, but it should be interesting to find where the bug is, and correct it, if possible.mathematicboyMon, 19 Nov 2012 12:02:30 +0100https://ask.sagemath.org/question/9547/
