I'm not sure I know what you mean by cancel but I suspect the answer is no, I can't. All I can do (and I could swear I did in the original thread) is support what I said. I recall an example of an integral with an exact answer. That is an example of what I mean, even though it's probably not an example of what you want. >> If you'd agree with that simple fact, I would not feel I have to keep >> pointing it out.

I did, didn't I? The simple fact is evidenced by many symbolic calculations done in systems like Mathematica. Engineers and scientists use these programs even though they may get exact results when they (being engaged with the physical world) don't actually need exact results. -- Ben.
