Sal your my hero. Ive never had any freinds to study with but when i watch your videos it becomes more fun to study because im not feeling so alone. Now many years after high school im finaly prepared to go for civil engineering. Thank you
He is definitely making a lot of money through Khan Academy, but the difference is that he doesn't require you to pay in order to access amazing, educational content like this, you can have it all for free if you want, or you could donate to him if you want.
Hello, thank you for the video. I wanted ask: at min 5:00, how you can just say: we "factor out" dt? First module would be needed (i.e. | dt | ), but above all we are pretending dt is a number or a variable which can be "squared" or "taken the square root" but it's not actually, it's an abstraction of infinitesimal small change!
It can be thought of as an abstraction, but it is also literally what the name suggest - a Difference in T (hence DT). It is infinitely small, but still a difference of values, which can be squared and factored out.
Hi Khan Academy, what is " Return parameter of curve at the point"? Can you analyze for me what does it mean? Where can I get it from? I am studying the problem of dividing the curve

Thank you
good luck out there buddy. i'm in second year of civil engineering . this man has been saving me hahahaha
Same. I've absolutely no friends but he's my math friend.
Thanks man you are an angel. Finally someone who works and explains concepts so easily
The man who does everything for everyone but never. Charges anything
The man is awesome for sure, but he is absolutely making money off his tutorials.

@@HDitzzDH yes I donated 20dollars to khan.
I did not find this prove in my textbook! Thank you for explanation.
