Dear fellow developers, I've encountered a really strange result in Sage while using Maxima.
sage: f(x,y) = (x^2-y^2)/(x^2+y^2)^2 sage: integrate(integrate(abs(f(x,y)), x, 0, 1), y, 0, 1) -1/4*pi This is really weird. At least, the result should be positive! SymPy however yields the correct result: sage: integrate(integrate(abs(f(x,y)), x, 0, 1, algorithm='sympy'), y, 0, 1, algorithm='sympy') +Infinity What is the issue here? Did I do something wrong, or is this a bug with Maxima? Best Michael -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
