I wanted to calculate Integrate[x^100/(x+2),{x,0,2}] and even the sign of the result is just negatvie. The reason is the same as above: Mathematica calculates the integral symbolically, using a hypergeometric function, then (s)he is unable to numerically evaluate it. I got the good result if I used NIntegrate. Janos Toth Dept Math Anal Budapest Univ Technol Ecol.
