Khan Academy should hire you. Your teaching style is very effective.

I'm doing Linear Algebra in University and this 2 minute video was more helpful than the 2 hour lecture my lecturer gave to me!

I love you man. Words cannot explain how much stress you have alleviated from me for school. You are the one who actually enables me to learn these math concepts.

Patrick, I learned more from less than 30 seconds of this video than from 2 hours and 30 minutes of my teacher's lecture. Thank you for being so clear and straight forward!!!

*Slow clap* Lecturer's notes were utterly useless... Saved my ass :)

I was staring at my homework without a clue, but I am totally getting it after watching all your videos on vectors, THANKS!!!

Today my professor made this concept seem so hard and complicated, but you just made it so much easier to understand! Thank you!

@khris2049 physics is just applied math!

[chriswilliams]

Thank you for the video.
I don't understand how it is a length of one if the components are <3/5, 4/5>

Hey Patrick! Great tutorial! I do have a question how do you verify your the answer? I just can't remember.
