Calculus: Derivatives 1 | Taking derivatives | Differential Calculus | Khan Academy

This video reminds me of how I used to laugh out loud midclass every time that I finally understood the lesson XD.

I am horrendously sick, and this saved my life

whoever made this video is so goated

Need to
Your help ,I was close to graduating, help me finish where I left off.

jesus...... can you talk slower and interrupt more? even at 2x it's painful. get a straight edgs.

Sal is an absolute legend.

Best explanation of derivatives I've ever heard. Kudos!

This dudes voice is a melody

why is it lim --> 0?

THANK YOU SO MJCH OH MY GOD I LOVE YOU

🦾🦾🦾

How I wish, we had this during our school days. Makes it so simple to learn. So many of us would have fallen in love with mathematics

15yrs ago 💀💀💀
I was only 2yrs not knowing that im literally going to watch and learn about calculas through this video 😂😂
This is insane

This video is older than me, and im here using it heheh. Thank you so much for this amazing explanation!!

I am taking a class where the reading does not make sense to me. This makes sense to me. I think if everyone just donated $1, the academy would have complete funding to provide free education like this. Donated money.

🌺This was posted the year I was born?!? God I feel old🌺




🌺also thanks for the help😉🌺

Wonderful

😙😙😙tnx

I was <4 years old when the video was uploaded.😄

thank you so much. You made calculus very intuitive not a scary thing.

This video was created when i was 1 year-old. Thank you so so much!!

thank u man...

nice

The quality of your videos are so low!

you used to sound like Jon Jones lol

awesome ..never understood earlier

that was helpful

Let me just say I have been doing differentiation for almost 3 years and for the first time today I finally understand how it freaking works. Before this I learned mostly by memorization since I never understood how my teacher or lecturer teaches. Thank you my dude I really appreciate it.

Why can't we just learn math from Khan Academy and get rid of these stupid schools and there Teachers ? Would save everyone a lot of money. This is the future. Its time to change the broken American Education System

I cannot believe that it was so easy and I was getting so frustrated of not knowing how to find the slope of a tangent line to a curve.... Thank you so much

We need new videos with more visual clarity and simplicity...these are getting really old

He is the Chosen one....

I always come here to learn!! keep expanding please for our children to be able to learn for free

Great explanation but the sloppy drawings does not help! Come on! A decent tablet and a basic drawing application would make it so much better.

I finally understand the concept of the derivative! Thank you!

video's nearly 15 years old and still saving lives
