# Talk:Limit (mathematics)

### From Conservapedia

who writes this stuff??--Lemonpeel 21:41, 3 July 2008 (EDT)

The math articles were written by random editors of conservapedia, I actually liked the earlier version of the article as it was easier to understand that the current version -- 22:05, 3 July 2008 (EDT)

## Function vs. Sequence

*Function should be first. It is more fundamental, even if it might be considered harder.*
I'd like to object. The idea of the limit of a sequence is the more basic one - and it's taught first, I suppose. Generally, you introduce the limit of a function in a point via the limit of sequences: What does it mean (in your example) that ? It means, you look at all sequences (*x*_{1},*x*_{2},...) with . And if for all these sequences, the corresponding sequence (*f*(*x*_{1}),*f*(*x*_{2}),...) converges to the same value *z*, you'd say that the function has limit in x.
But without this underlying concept, the expression is unmotivated and baseless. --DiEb 18:11, 17 August 2008 (EDT)

- I have put the order back the way you want it, but I hope to convince you that putting sequences later is the right thing. That is, do ordinary functions first, functions going to infinity at finite X second, and functions going to finite Y for infinite X third. This establishes the notion of "for every epsilon there is an M such that x > M get f(x) within epsilon". The sequence version of a limit is just a simple variation of that notion.

- By the way, greetings. You and I seem to be the only math/science people left. Well, I notice that Lemonpeel has just come back, but things don't seem to be going well for him, and I suspect he will be out soon. My attempts to get the natural log page and the radioactivity page restored have met with no success at all, and I can't keep asking, since I'm on extremely thin ice.

## New version

I have copied this from SamHB's sandbox. It appears that he had left the mainspace article in an unfinished state. PatrickD 23:59, 7 July 2009 (EDT)
