Epsilon-Delta Proof (Quadratic)

In this video, I explained the steps in proving the limit of a quadratic using delta-epsilon proof.

My first time to appreciate someone on YouTube

[VasilEPetkov]

My professor prooved the same thing to us. He skiped all the (un)necessary comments what's coming from where so I was so lost looking back at my notes. Your videos are for sure saving me :D

[isabellacrow]

This is it. Two hours of working on the same delta-epsilon problem, and this is the video that made it click for me. Thank you.

Mathematics becomes easier for me because of how you explained it in such simple ways....Thank you very much

[mrhunterai...]

You're really making our life much simpler and thanks a lot. You simplified the proofs very well.

You are One of the Great Teachers i have ever seen Thank a lot!!!!

First I need to tell you that you have great videos with excellent explanations. These definitely make math learning interesting, enjoyable and easy to understand. The point of this comment is to let you know about a very important notation matter. When we right limit at the beginning without a parenthesis, the limit only belongs to the first term. So, the correct way to write it is to use a parenthesis around all three terms as lim{ x → 1} (x²+5x+6) = 12. Keep doing what you are doing. Thank you.

9:18 I did the same expression and the meme appeared! Truly magnificient! YOU GOT ME! LOVE FROM INDIA

I spent an hour working on one of these proofs and this video was the one that showed me how to replace the factored part (|x + 6|). Thank you so much

[AdrianYung-ooqf]

I love the way you are so enthusiastic about teaching!! thank you so much for the video :)

[hriday]

This is the best I have ever heard this concept explained. I was struggling with understanding how the proof worked for the past 2 days, and I finally understand now. Thank you!

[jhonnatanmontano]

OMG !! You are an amazing teacher. Thank you so much 🙏
I’ve been trying to understand this for a lot and is the first time I feel like I get it.

[TinotendaMuchenge]

Plus the way u smile doing some cracks, while solving, its just fantastic, u wont be left with any qsn

[solha]

Bro you are amazing, i mean you have the talent to be a teacher bc you try to understand the students❤❤

[lusianelundu]

Your handwriting is dope sir and I love the way you have explained.

[anvarkhaydarov]

Thank you so much for the explanation. Watched bunch of other videos and yours was the simplest to understand

[mohammedaminelm]

You are the best math teacher that exists!

Hey, first of all, i really like your videos. You are doing a great job!

I am a fan of generalizing the epsilon-delta-criterium and give a specific formula for delta. What I found out was that, if you choose for a general x_0 (which is in this case 1 of course) the formula delta (epsilon) = - abs(x_o) - 5/2 + sqrt( epsilon + (abs(x_0) + 5/2)^2), you get a guaranteed delta for any epsilon > 0 that you choose.

Thank you for your great videos again. They are very inspiring!
