You explained in 5 minutes what I couldn't understand after a week of classes. Thanks!
What does this guy look like? I need to put a face to the voice!

horrible video actually. he only used easy values: 1's and -1's. should have shown steeper ratios 2/1 3/1 10/1 etc to show how the angle changes to prove the resulting shape of the slope field instead of just making it up "here! it is a circle. done".

How do I redirect the force of gravity into differential equation slopes that I can surf?

Ok...well after trying to learn this in my textbook I sought this video to clarify the basics. I didnt think my book did it well, but this...this helps a lot! Now I need to apply it. Thats the hard part.

@Mars TV Channel: -1/0 is not equal to 0. I believe you may be applying the same logic from that of 0/n, to that of n/0. Dividing any kind of number by 0 is undefined. There are interesting videos out there explaining why this is so.

How can -1/0 be undefined? It's 0.

Anything over 0 is undefined.

I would love to see some fancy thumbnails on these videos, would drive new user traffic quite a bit (one would imagine).. Thanks Mr. Khan!

After finishing the series on differential equations can you post some real world examples ? Like solving the Schrodinger equation or some other physics differential equations :) Keep it up you're the best
