Thank you,

Trying the YouTube #shorts feature, it’s perfect for my math speedruns!

Please, let me know if you get this video as YT #shorts.
I want to make sure that I did the process correctly. Thank you.

probably the quickest Epsilon-Delta proof I've seen. nice job! (would not expect anything less from a math teacher...)

[blackpenredpen]

Okay, besides trying to understand YouTube Shorts, I wanted to tell you that pay attention to how I structure the εδ proof.

You first write down "let ε>0", second "choose" δ=, third "suppose" that inequality, then "check" the final abs. inequality.

I hope this format helps and I will do a regular video next week to go over the details and other examples.

Hey I watch youtubers that generally end up popular. You're about as popular as a mathematics tutor can get. You're good at what you do, so please keep making content that stays true to your wholesome passion for mathematics. Educators with a wholesome passion for mathematic, like you, give me hope that mathematics might be mostly enjoyed one day.

This speedrun proofing is so impressive <3

Black pen red pen is not less than a legacy in our pass it to our younger ones

Me : Oh, it's time for online classes.
Bprp's proving epsilon Delta limit in "50 seconds ".
Me : Hmmm interesting 🤙🏻🤙🏻

[THotSouce]

Dude, this is amazing, thanks for the amazing and quick explanation

[snejpu]

I've never understood epsilon-delta conception at all. Why do we choose delta so that we achieve epsilon in the end? And what does it prove that we have epsilon in the end? I don't get it.

You and 3Blue1Brown have the best content!

[jayska]

Im a recent subscriber and your content is great. God bless you bro

[htikeaungwai]

Love from Myanmar 🇲🇲
I really enjoy your contents.
Maths really feel like an entertainment, thanks to you 😂

[giggiononmiricordo]

please can you make more exercises than this? you are an absolute giant and you are really helping me with my calculus exam ;_;

[chicken_asmr]

Can YOU PLEASE TAKE THE OXFORD MATEMATHICS ADMISSION TEST I REALLY WANNA SEE THAT

[QuillPGall]

i’m in my undergrad for math education, and it’s been interesting seeing these proofs come back in my real analysis class

[alexnixon]

I'm so glad I found your channel. I suck at math and need all the help I can get. Thanks for what you do!

[theotang]

For those who don’t know
The limit is correct if:
For epsilon>0, there exists delta>0 such that when 0<|x-a|<delta, |f(x)-(the answer)|< epsilon

He chose delta to be epsilon/4, it’s >0 because epsilon>0 and he proved |f(x)-L|<epsilon by using 0<|x-3|<delta so this limit is correct

[dreamdefence]

you are very nice teach to math
I from India i am studend of class 12th

[lailin]

I am so happy to see the video in this topic.
I was just studying the same cz its in syllabus.


True fan from India
