I have to perform a symbolic integration and I some problem with it!
(I use Mathematica 4.1)
The problem is that when I use NIntegrate the result is 0.852711 (that is pretty true),
instead using Integrate and performing the integration symbolically the result is 3845.27
The function is quite long so I put it in the attachment, but it's not really complicated, just long.
N.B.= Integrate works (with such bad result) only using Together[f(x)], otherwise it left the integration undone!
Thanks to whoever can help me!
