Wow wow wow, amazing. Hours of pounding my head and finally get it!

I wish this was my class during covid enviorment

[vamshikrishnakoganti]

Are you actually writing in a mirror image so that we can read??
Or is it a post production where two video's are synchronized..?

If yes, hats off ....!!

I suggest showing an actual matrix and then tell that this is this kind of matrix. Instead of introducing the matrix type verbally and directly jumping into properties.
If not shown an actual matrix, these Qs and other matrix notations are only letters for us.

Short and easy to understand, thanks!

[pipertripp]

very helpful. Allowed me to reason about the answer to a question in my problem set.

If two vector are orthonormal, does that mean we can use those vectors as basis vectors? (Also Does basis vector need to be normalised?)

I didnt understand anything but great video btw. guess I have to find a beginner friendly one

@ 2:47, how does (Qx)T (Qt) equate to norm of (Qx). As mentioned in the video, its by definition. Have I missed something or there is something else.
Thanks for these great lectures. really helpful

QQ'=I only if its a square matrix right ?

[germin]

he's definitely jeff benzos brother

[jacobvandijk]

A stunning lack of examples. Talk less, write more!
