Man, I just took some of this last semester and already it's gibberish.

Streuth, I remember doing some of this stuff when I was 16, but I didn't understand much of it even then !

However, I would bet the answer is either zero, one or infinity ;)

Bah! Antiderivatives! Not so bad on their own, but derivatives...

Forget the Aztec sacrifices, derivatives, derivatives are the tool of the devil, I tell ya! The tool of the devil! Gagh!

∫ f�(x)dx =f(x) + C

Well, the answer, trivially, is e to the x of course. So?

That ? mark is an error, it's supposed to be an apostrophe (prime).

∫ f '(x)dx =f(x) + C

I'd still back my previous answer, with the caveat that you may not KNOW what the answer is. If the answer turns out to be X or X squared or something, but without a value then its as meaningless as the question

It's just general formula that is always (almost always???) true, not equation (dont' know if I use correct words).

It's like (a+b)*(c+d)= ac+ad+bc+bd (which is always true), and not like x+3=6 (which is true for x=3)

I think so.

I wonder however, how you managed to do taht symbol ∫

You are correct, but trivially so. The point is that it is the Fundamental Theorem of Calculus.

I used Microsoft Word, cut and paste the ∫ symbol in Internet Explorer and voila, since I don't know the Unicode number for it (for browsers that can read Unicode, that is.)
