9 years before and still understandable. Greate Teaching sir 🗣️🔥

I've learned many things from this video more than my unv. professors' 2 hours lesson.
You've been really helpful.

Wonderful lecturer that makes physics fun and understandable !!!

[hinamohamed]

your videos have been helping me alot
thank you

excellent description but a bit short still needs more

Gotta say khan academy linear algebra unit vector video was actually better as it explains that unit vectors are NOT just direction like this guy confusingly says; instead a unit vector can be thought of as I which is <1, 0> along the x axis and j which is <0, 1> along the y axis. So we are scaling up the unit vectors to get the final vector!

uh that wrong because the magnitude of them will be greater than 1?

To find that unit vector they need to do (5i+4j)/sqrt(41)

When you realize he’s writing backwards 👀

[Cpt.Rommel]

you got serious sound problems in each video, i recommend you to consider your video edit programs.

When one denotes the components as Ax and Ay then direction of each component is explicit. Then the notations i and j are redundant. So either denote components as Ax or Ai and Ay or Aj but not the overkill of Axi and Ayj.
