I found this topic to be very boring but the idea that a cofactor expansion will give you the same determinant regardless of where you want to establish your expansion is actually... pretty cool. Who would've thought
can i use the +/- A1j Det(A)1j and subtitute different rows for 1 or do i strictly have to use the Cij formila when working with anything other than row 1
youre not the stepmother, youre the mother that STEPPED UP! Clear, concise, top video!!!!
You're an amazing teacher! Keep up the good work.
Carrying my Linear Algebra grades even today
We all need to come together and buy Mrs. Brehm a gift - and not a cheap gift
So sweet! I wear "Ocean front property" haha
man, this cofactor method is so cool
Agree!

We must protect Kimberly Brehm at all costs. This video is so helpful.
I hope you rest well knowing you help terrified students like me feel a bit more prepared haha
Well done video again!
"Since I know you're having a blast"😂
You're explanations are awesome!
So, essentially we recursively compute the determinants until we reach the base case which is a 2x2 matrix?
Matrices are magical.
amazing
Thanks Kimberly.
'geeked out' ;o
Thank you.
Thank You!
Thanks a lot for wonderful content, may I know which text book you are referring to ?
Linear algebra and it’s applications by David c lay

for the last one, when computing the determinant, I used row 1 and I got 8 instead of -8 which is weird.
(-1)^2 is 1.
do we do the same thing with a 5x5 matrix
co factor expansion like the 4x4
