Calculus Made EASY! Understanding the derivative 

Viewed your previous video on calculus and only 1/2-way through this one, but this has already been the most clearly and concisely presented material I’ve watched regarding the subject online. Fundamental concepts are covered that have often otherwise ignored by others. Plan to watch the next and hope to see more. Much thanks for producing this.👆

This is one of the master piece available on youtube. Sir you are great. I am glad i found this channel. Please keep up the good work in making difficult concepts easier.

Everything is adding up from what I didnt understand in class

You’re the best. Thank you so much.

Just finished self-studying precalc/trig and now I'm ready to take calc for a spin. After watching this video I've decided to make you my official calc teacher, lol. Learning math to become a better software engineer, but also because I thoroughly enjoy studying it and using it to do cool things.

I learned more about calculus here ..than my entire education
