@JanDvorak since it's a continuous function, lim u -> x+ is indentical to lim u -> x-, so lim u -> x is?

@Unihedron can you prove that from definition?

user259867

@JanDvorak In order to prove the statement about limit from the left, you must show: for every epsilon>0 there is delta>0 such that if x-delta<x'<x, then |f(x')-f(x)|<epsilon. Since you know f is continuous, the definition of continuity can be used. It gives you delta such that if |x-x'|<delta, then |f(x')-f(x)|<epsilon. So, the definition of the left limit is satisfied.

user259867

Informally: given epsilon in the definition of limit, you stick it into the definition of continuity, and get delta from there. This delta works for you in the definition of limit.

Vogel612's Shadow

> "If you really need an invocation pattern you can use '$', that's one I used to use"

okay wonderful, we got someone who is giving out allowed invocation patterns!

Unihedron

Right?

Jan Dvorak

4:56 PM

Is your definition of a limit the same one as that of continuity? If so, I've been using the wrong one...

Lynn Crumbling

@JanDvorak We had to memorize that definition for our foundations of math class. Bah.

user259867

They are very similar. In the definition of limit we have |f(x')-L|<epsilon. What is yours?

Jan Dvorak

in RegEx on Stack Overflow Chat, 14 hours ago, by Unihedron

fools rush to where angels fear to tread

Jan Dvorak

Do I read correctly that the definition of continuity is that f is continuous at x iff its limit at that point is defined and equal to its value?

user259867

5:03 PM

Yes, this is how it works for functions defined on the whole real line or on an interval of it. There is a subtle point with functions whose domain of definition contains isolated points, like [0,1] and point 2. Then there is no limit of f(x) as x->2, but f is still considered continuous at 2.

Infinite Recursion

.... and uni rushes in to every chat room

Jan Dvorak

continuity can be weird...

user259867

Much of this is up to the choice of professor / textbook author. Some will adopt the definition of continuity that is in terms of limits: i.e., exactly what you wrote. Others, including me, will follow (epsilon,delta) definition of continuity, which is similar to def. of limit, but does not invoke the concept of limit directly.

user259867

Actually, I'm not sure this "report" thing is a good idea: why go to SE Team over the head of site's moderators? Normally, I would just flag any post by the problematic user (or even my own post) and explain the problem to a moderator.

Vogel612's Shadow

@WeaponofChoice and if you want to (hypthetically) flag a mod?

Unihedron

@Vogel612'sShadow In the past you would have to mod-flag a post.
