(Edit: I said something kind of stupid here. )
I was about to respond to the thing you said was stupid, but it was gone! :O :O :O
I'll respond to it anyway. I've actually not taken a single bit of calculus officially. I've just studied it in my free time, because I know that will help me in the future (I want to do physics in college, and from what I've seen, it requires a lot of calculus). It's all for fun anyway, and I was just curious about something, so I thought I would ask here (I'd already looked at a few other places and couldn't find anything).
