But Sympy returns a result for x**x as well. It is just not in terms that most will find easy to understand:
>>> integrate(x**x) Piecewise((x*x**x*gamma(x + 1)/gamma(x + 2), Abs(x) < 1), (x*x**x*gamma(x + 1)/gamma(x + 2) + gamma(x + 1)/gamma(x + 2) + gamma(-x - 1)/gamma(-x), Abs(1/x) < 1), (meijerg(((1,), (x + 2,)), ((x + 1,), (0,)), x) + meijerg(((x + 2, 1), ()), ((), (x + 1, 0)), x), True)) On Monday, May 27, 2013 10:53:22 AM UTC-7, Aaron Meurer wrote: > > What is a good example of a (preferably simple) integral that SymPy > will not likely be able to ever do, because there really aren't any > closed forms of it, even in terms of special functions?
