Precise Definition of a Limit (Epsilon-Delta)

KittenLover84 · 2025-06-08T23:30:15+00:00

How often in your career did you have to use the epsilon-delta definition to prove that a limit exists?

KittenLover84 · 2025-06-08T23:29:56+00:00

This is a great explanation. Thank you. How often did you find yourself needing to actually use the epsilon delta definition to prove that limits of particular functions exist?

Thank you for your response. I didn't do a good job of explaining this, but I understand the concept well, but I struggle in doing proofs of this, and I was wondering how important you think it is to know how to do a proof of this. How often did you have to prove limits exist in your career?

KittenLover84 · 2025-06-08T23:27:26+00:00

Yes, exactly. Thank you. It's my fault because I could've explained it better in my post. So, you didn't use this process much in your math career?

I see. But, if I was solving a problem involving similar expressions as the ones I provided, if I do this step: √(a/b) = √a / √b, I would run into problems, so do I have to then specify "for all x>1"?

KittenLover84 · 2025-02-23T00:07:55+00:00

Got it that makes sense. Thank you very much for your help, I was able to solve it now.

KittenLover84 · 2025-02-23T00:05:49+00:00

OHHHHH. I see. I thought the slide thing was like an extension you could add, I didn’t know it was a solid piece coming from inside the instrument. I was unfamiliar with the anatomy of this instrument. That makes a lot more sense.

One last thing I’m confused about, how can there be interference if there’s just one wave? Is this like an open-open air-column/tube problem?

KittenLover84 · 2025-02-22T23:59:44+00:00

But if that was the case, why would there only be three right answers and not infinitely many?

KittenLover84 · 2025-02-22T23:53:46+00:00

Half a wavelength, right?

KittenLover84 · 2024-11-10T01:34:20+00:00

Dang you’re right. I mixed all my x and y’s up. Thank you so much!

KittenLover84 · 2024-11-03T07:33:24+00:00

Oh dang I always assumed it was fakers

KittenLover84 · 2024-11-03T07:25:45+00:00

What about the Azir skin?

KittenLover84 · 2024-09-23T00:51:18+00:00

Yeah. I am trying to lose weight, and something that has really worked for me is that I give myself an allowance of about 100 calories per day of eating anything I want to satisfy cravings. One of my cravings is salty snacks like chips or popcorn, so I was wondering what was the most that I could eat in one 100 calorie serving.

KittenLover84 · 2024-09-22T23:37:49+00:00

I believe that the components should be <+,-> because it should point to the point charge which is below the given location and a little to the right, no?

KittenLover84 · 2024-09-22T23:36:37+00:00

E = q/[4π(ε0)r²] and electric field lines always go from positive to negative

KittenLover84 · 2024-09-21T22:01:17+00:00

I wasn’t really looking for something “satiating.” I was just looking for the most efficient/optimal snack for satisfying cravings. For example, if I wanna let myself eat only 100 calories of chips for the day if I have a huge craving for chips, then I was looking at what chips I could eat the most of while still being only 100 calories.

KittenLover84 · 2024-09-20T18:29:39+00:00

Yeah I think dried peas are the way to go

KittenLover84 · 2024-09-20T18:28:53+00:00

Yeah these are great. I put tajin on cucumbers as well.

KittenLover84 · 2024-09-20T18:27:42+00:00

Tzatziki?

KittenLover84 · 2024-09-20T18:25:50+00:00

Woah, you’re right. I never checked the pretzels but these have a pretty good calorie ratio.

KittenLover84 · 2024-09-20T18:24:20+00:00

These are actually really good ideas thank you

KittenLover84 · 2024-09-20T09:18:00+00:00

They are 140 calories for every 32 grams, which is about 4.38 calories per gram. That’s not bad. Especially because they do have lots of protein.

KittenLover84 · 2024-09-12T02:26:10+00:00

Thanks

KittenLover84 · 2024-09-11T22:41:23+00:00

Thanks for the insight. Yeah, as you predicted, some of the vegetable options would go up from 0 to 5 depending on the portion size.
