Do you think I could just leave this part blank and it'd be okay? We're just going to replace the whole thing with a header image anyway, right?

Yeah, that’s how limits work.


One bot to rule them all, one bot to find them. One bot to bring them all... and with this cliché blind them.

Hummer’s dilemma is finding out whether this is almost a **** post.

Re: Almost dividing by 0

Now that he is learning about limits, get ready for a hundred of topics trying to disprove them. I certainly do not know what will happen when he learns about integrals...

Re: Almost dividing by 0

But what if you divide a pie by almost zero!?

You can’t do that because it doesn’t make sense with a physical object, even though much of maths is conceptual so the comparison is irrelevant, but in conclusion limits don’t exist and the maths is wrong.

not quite since that's the right sided limit (if x>0)
the left sided limit will be the opposite (-infinity if x>0)
so the limit doesn't exist even in the extended reals

(well, there are situations in which it makes sense to consider infinity and -infinity the same, but it's not the usual situation for this)
