Hi, sage 5.0 beta11, on Fedora 15, AMD Phenom II X4:
sage: f(x) = sin(x)^2/x^2 sage: f.integral(x, -infinity, infinity) x |--> pi sage: f.integral(x, -infinity, infinity).n() 3.14159265358979 sage: f.integral(x, -50000, 0).n() + f.integral(x, 0, 50000).n() 3.1415769097886317 everthing fine so far, but sage: f.integral(x, -50000, 50000).n() 0.06953294323974919 sage: f.integral(x, -5000000, 5000000).n() 0.002749874456609362 Am I over-worked, or is this a bug!?
