"Differentiability is the continuity of the first derivative"--- this little thing has bugged me for months. Thanks for your efforts.

4AM rn. Exam tomorrow and I'm behind again...
Redbull in hand, with caffeine shakes inbound, I want to genuinely say thank you for doing what you do.
If I had cash of my own to spend, you'd be receiving a donation and a lengthy email.

"Differentiability is the continuity of the first derivative" - One of the best quotes in mathematics. Thank you for everything you do

salute to the man who makes this concept look like addition and subtraction

The title is about one topic, but he always covers many topics in his video. Therefore, I can learn more than one. Love it.

[Ririanni]

I studied in class for months : 0 knowledge
Watching this video for 32 minutes and 47 seconds : 99.999% of knowledge in my 🧠

Thank you so much.

5 am rn. Exam at 9. Why does it seem so easy all of a sudden? Just thanks a lot man. May Allah bless you.

[shahadmerani]

IVE BEEN STUGGLING WITH THIS FOR MONTHS😭 my college entrance exams are in like 2 days YOU LITERALLY SAVED MY LIFE, THANK YOU.

[Edigor]

Your videos are great because you're doing things differently than other youtubers. Other youtubers only show very trivial examples so there's not much to learn from. You however show problems that are difficult enough that you can transfer the knowledge to harder problems and that really helps me a lot with my understanding about the topics you teach/explain

[manzidelick]

I am deeply moved by how differentiability and continuity have been simplified in just 30 minutes, I'm very thankful bro, all my classmates will be impressed and greatly helped by this video 🤝🤝🤝🤝

[backflipinspace]

i've never understood continuity and differentiability this well. thanks a lot!

[Vijay_helo]

Bro... I think you are a legend. No one single channel has covered all maths and science for all ages!

[DadsCornerLew]

Honestly I've spent hours on other sites trying to understand stuff that you explain clearly in just a few minutes. I've never had any real motivation to join patreon but to show my support for what you do I'm about to sign up.

[tasongenowoa]

If I could have access to videos like this during my university days I would have had a better GPA. You are awesome.

[AnasKhan-gtqe]

OH MY GOD you have no idea how much helping are your videos, you are saving grades in the last hours of their finalisation.

[هدىسعيد-قق]

THIS IS THE BESTTT CHANNEL EVER TBH YOU JUST A LIFE SAVIER CANT EVEN THINK ABOUT HOW MANY TIMES YOU SAVED MY POOR MATH UNDERSTANDING THANK UUUU 😭👏🏼👏🏼

[SivaSiva-kt]

Hope these videos would be available for some centuries ...
All is well...
