@TheEarlOfDublin No Kidding!!!

I always didn't understand the difference between points and vectors and everything was always so vague. Everything is very clear now thanks to you.

First let me say I think your achievement as regards these educational videos is nothing short of remarkable, and I for one am very grateful for all the effort you have put into them. There is one small error in this video at about 4:30-5:30 at which point you indicate that a vector can be defined as originating from any point (x1,x2). You write (x1-1,x1+2) when I think you meant (x1-1, x2+2).

dude...khanacademy is the best.....wish my high school teachers were this good !!!!

Just wanted to say that you made a mistake when drawing the vector (-6, -5). You inverted the horizontal and the vertical coordinates, which makes it not colinear.

@TheNachoKat i know its 7 months late but i just cant help it... hes talking about how you able to scale, flip, rotate your picture in your cellphone and another would be how you be able to play video games in xbox, pc, PS3, and wei , and how you able to watch CG Films among others because its list application in REAL LIFE goes on and on

Huh, okay :D Well at least now I can have some idea of it, It doesn't feel good to be ignorant of something. :S

@TheNachoKat WHen making video games that use 2d or 3d graphics. best believe ANgry birds is all about the vector math, SON!

At 04:35, you write (x1-1,x1+2) but I think you really mean (x1-1,x2+2).
Thanks for these videos!
