You're the best fucking teacher of this shit I've ever seen, and I don't even speak your language. Felicitaciones, profe!

Brother this is one of the most underrated videos on calculus. You are a great instructor.

Why can't my professor have the enthusiasm and articulation that you have for math? This is the first time I sit completely still and watch a math video without being distracted or  completely lost.

Thank you, really helped me in my math journey, love from Pakistan♥

This video reduced my Calculus anxiety sooooooo muchhhhhhh, thank you for keeping it so simple and easy 🎉

I’m turning 25 and thinking of going back to school. Brushing up on basic stuff that I’ve forgotten over the last 7 years on Khan academy and feel like I’m going to be better equipped to actually understand calc this time. I was a huge stoner with poor work ethic when I took calc my first two times lol. I think I also never grasped the big picture of how everything relates and got lost into memorizing formulas for what I thought was no reason. This video helped a lot.

this video made me excited to learn calculus im shocked. ur a great teacher!

I'm struggling with calculus, I blame my adhd. I understood this video though! Thank you!

This has to be one of the greatest videos on the internet! ♥️

You are one of the best teachers i ever saw. U explained calculus smooth like butter

The explanation, the visuals, and the weaving together of the concepts all help so much!!!

For me in the US, differential calculus was taught as "pre-calculus", then Calc I was integral calculus (both in high school). Then Calcs II and III were college courses (differential equations then vector calc, I believe). I don't remember any of it 😅

It's beautiful how to simplify a whole branch of maths in few minutes.

I don't know the actual reason for you being so underrated but you're one of the best Maths teachers  i've seen so far on youtube .Love from India ❤❤

i just got into 11th grade and you have no clue how much this video has helped me, AND ON TOP OF THAT I WASNT EVEN DISTRACTED THANK YOU SO MUCH

mind boggeling experience, Appreciating your effort.

I like your direct no nonsense practical approach. Demystifying calculus is a great step towards being confident in learning the process.

I loved the question 10: 27

Great work! Love the Mozart in the background - nice touch.

Solid explanations
