@@lattice737 You're totally wrong, stop spreading false information. The video itself confirms he made a mistake at 2:55. There is a scaling of -4, not 4 as you mention. I hope it is clear now for anyone reading this that was confused.
Marius van Gent I see what you mean at the time stamp. I’m obviously not intending to spread misinformation if I’m taking the time to show my work, jackass
13:35 I wish you showed all the steps instead of talking over and only writing the final answers. Otherwise, very helpful video thank you for your time .
My guy!! You explain it better than my college professor.. All my profesor did was "here's your equation, don't ask how you get it, just use it" Like... Bruh💀
It is a elegant explanation of elementary matrices. Thank you James
In the beginning I think you meant adding -4 R1 to R3
4R1 + R3 leaves one value, 1, for the first pivot column. -4R1 + R3 would leave -8 and 1 in that pivot column
@@lattice737 Can you explain how It would leave -8 in R3's first column?
@@baguettebaguetteneverforge1758
Just to be clear, I was saying this is the wrong answer:
-4R1 + R3 =
-4 [ 1 0 0 ] + [ -4 0 1 ] =
[ -4 0 0 ] + [ -4 0 1 ] =
[ -8 0 1 ]
The correct answer is:
4R1 + R3 =
4 [ 1 0 0 ] + [ -4 0 1 ] =
[ 4 0 0 ] + [ -4 0 1 ] =
[ 0 0 1 ]

This is the best explanation for the means of deriving the inverse matrix, thanks so much James!
sir ,you are just awesome .the most clear explanation i got....thank you so much.may Allah give you blessings

So much better than my professor!
best explaination ever on elemnatary matrices.....
are u crazy

Hey! I didn't understand the last part (15:00). Can anyone please break it down for me in simpler terms...
Thank you for making these videos
Thank u for explanation...this really helped me to understand ♥️👍
Great explanation. Thank You.
What a quincidence I m watching this video on 7 June 2020 ... Exact 2 years after this vdeo uploaded 🤣🤣😎🙂🙂
Thank you so much, James :) It is the best explanation i've ever seen.
Thank you, considering an arbitrary matrix is the best way to describe elementary matrices! Wish I found this months ago.
Thanks!!!!! its helps a lot!
Is there a quick way of finding A=EU by hand?
Thank you sir for ur video
Thank you my teacher did not explain this at all.
Is it possible to find the inverse of an mxn matrix or do inverse matrices only exist on square matrices?
Only square matrices can have inverses.
@@HamblinMath thank you!
It is possible to have a right inverse for an mxn matrix. (AB=I, where A is mxn and m
Incredibly appreciated. Very well done video.
Thank you so much 🙂🙂🙂
THANK YOU!
Thanks...... So helpfut
Don't you mean adding -4 . row 1 to row 2
Can you give a timestamp to where you think you found an error?
@@frettenbrot Ah you're right, that should be adding -4 times R1 to R2

you saved my ass Thanks!
Why do I still pay in expensive university???
