Then I just checked a couple of values, comparing the derivative of the "anti-derivative" with the integrand above. They were more or less the same. Lastly, I computed numerically a definite integral of the above and compared it to what I obtain when plugging in the boundaries in the Mathematica anti-derivative and subtracting. This, however, yields only in about 80 percent of the cases the same results, which is rather confusing...

But if Mathematica can give me a solution, then there should be a way to do this. Don't you think?
