Hi, I have two questions, one might be thought of as a bug report / feature request, please tell me what you think. Trying integrate(x, x, 0, infinity) raises ValueError: Integral is divergent.
My first question: why it does not simply return infinity? (it does, by the way, if one chooses algorithm='sympy') Now, trying integrate(ceil(x), x, 0, infinity) returns something weird: limit(1/2*(2*x + 1)*ceil(x) - 1/2*ceil(x)^2, x, +Infinity, minus) and trying to evaluate it with `.n()` raises TypeError. My second question: why it does not return infinity / raises ValueError: Integral is divergent..? And now, two more observations, which are certainly bugs: Bug 1: running integrate(ceil(x), x, 0, infinity, algorithm='sympy') raises AttributeError: 'module' object has no attribute 'ceiling'. I am not sure, but I think that the problem is that in sympy there's no `ceil` but rather `ceiling`. Bug 2: running integrate(floor(x), x, 0, infinity, algorithm='sympy') returns integrate(floor(x), x, 0, +Infinity) and trying to evaluate it with `.n()` returns (!!) -679.7441466712775 Should I open 2 tickets for these last two bugs?
