i know you probably hear this a lot but you teach way better than my teacher and i learned more right there than i have in like 2 75 minute math classes

Do realize that you are not actually talking to him? Khan academy is a company this is not HIS youtube channel.

He still looks at his companies channel you know

I've never heard anyone say that it's a waste of time to memorize the distance formula. But he's right!! All distance calculations I've ever done have been on graph paper; I can always make a right triangle!

[@YB.......003]

yooo when the teached puts the formulas on the table he thinks youre supposed to understand everything and keeps puting random numbers which i dont understand where they came from and im stuck there wondering about my existence in life and should i just jump off a cliff bcz i feel stupid

Wow thank you very much, I look like a genius to my classmates now, though I just watch videos and prefer to understand it. But you're videos isn't just a just, for this will help people who are savaged by mathematics.😉😉😉keep it up!!!

[@mosesvalentin1600]

You can also apply the distance formula to a three-dimensional system. sqrt((x1 - x2) + (y1 - y2) + (z1 - z2))

We need to tell that to Khan Nunyen Singh.

[@ogbogati_killer_2188]

Can u tell me if the distance for (-6,-10) (-2,-10) = square root of 18 is correct

[@isaiahphillip4112]

It should be the square root of 16, you don't need the formula to figure this one out. You can see that since they have the same y value (-10) they will be on the same x axis, therefore the distance between them is simply the absolute value of the difference between the x values |-6 - (-2)| = 4
