i guess 49 + 9 equals to 58., not 57 ...

Chill guys, even our teacher can get that wrong too, nobody is perfect. BUT, he should check the video twice for sure, but I will forgive you

In the title of the video it should be "calculating" not "calcuating."

If u is a vector quantity then |u|means the magnitude of the vector u but what is the meaning of ||u|| it mean the same or is it something
Waiting for a reply😑🙏

Out of all of the videos he made, making one or two mistakes isn't that big of a deal. I mean, that was not the point of this video (we don't really care). Moreover, go on Khan Academy as he corrected it by a side note on the video.

too bad most of the kids watching these videos won't see the big picture. and by that i mean the cool shit you can do with this. when combined with the knowledge from those other similar videos.

yooo, might be wrong, but i think its 58

[uwu_kitty_games]

Actual answer would be sqrt58, or 4sqrt(3)
