[Linear Algebra] Computing Ax and The Identity Matrix

[@simonhiggins7714]

Great job Trev. Your videos deserve more views. This is the best playlist on Linear Algebra I have found on youtube. I have recommended your videos to fellow classmates.

Proud to be 3461st viewer. Given the quality of the lectures, i'd say i should be in the millions, but we're all glad for the content regardless, Trev!

So the identity matrix is basically like a matrix of the reduced echelon form without the augmented column

[@programmingprograms726]

Thank you so much for this! What app/software are you using to write and record this? I'm curious.

[@DarshanSingh]

thanks for your lectures. Its help a lot to understand linear algebra i'm also want's to know how to use pen-tablet as you

[@programmingprograms726]

@DarshanSingh how does it work? Do you know what app he's using?

[@jozamaymen]

I have a little confused right now that where i should start to understand matrix. will be good if you could put a number beside the title of the video.

Grade A content!

Can you only find the identity matrix of a square matrix?
