God bless you, I was struggling so much to understand about this topic

just, how simply you do this proof man
u r amazing

Great work Mr Newton .keep on uploading, we don't want to stop learning

ooooh wow i had difficulties at this concept but now i have understood and now im academic weapon at this concept🥰😀😀. ok so what if
1. the limit is negative?
2. as x approaches positive infinity?
3. as x approaches negative infinity?
or else if you have already uploaded videos concerning these concepts you may just refer me to those videos, your response is my pleasure, thanks in advance🙏🙏🙏

I love you man you made the lesson so much fun

I think this is the first time I've seen someone prove a function ISN'T continuous with delta-epsilon. Cool!

The way I think of delta-epsilon is, suppose you're trying to prove the limit at the point (a, L). So, I imagine a rectangle centered at (a, L), that is narrow and tall enough that the function never hits the top or bottom edges of the rectangle. Can I create such a rectangle? And, can I shrink that rectangle down to zero width and zero height, and the function never hits the top or bottom edges at any scale?

The arithmetic of delta-epsilon is about starting with |f(x) - f(a)| and finding some way to make a standalone term of |x-a| to pop out. Once you've done that, get rid of any other "x" terms by replacing them with the value that makes the whole expression as large as possible.

thank you so much for explaining this subject! My calculus book wasn't quite good at explaining it, but your video taught me clearly how to do it :D
I also love how happy you are while doing mathematics, its infectious!

do you have a video about proof of limit at infinity I couldn't find it on the playlist
