I love your content, I learn it much better than the college videos. Thank you very much. Just by doing the Khan Academy I was able to do CLEP tests and got college credits.
I only have one critic, your 9 and 4 looks exactly the same in this video when you number the x-axis. Precision matters in all Sciences, but especially in Math.
Thanks, Sal
I thought you were going to make a higher order approximation using finite differences xD
Great explanation still!
What does the Tangent point mean? And what does it represent?
Hello! What subject or "level" of math would this correlate to? Thank you so much for this btw!
Kelly Li This is calculus 1
If they ever do a demo lua class for scripting that'd be great
But the shown curve can be flipped up side down which makes the derivative at this point NEGATIVE!
Oh. And of course thank you so much.
