Determinants and row-reduction

Calculating determinant using row-reduction, this is generally more efficient than using cofactor expansion

A few decades back, the BBC's Open University regularly broadcast material like this. Lecturers were quirky, but confident - and the population learned so much from their shows.
You have captured the spirit of those shows, and helped me to catch up with something I'd wanted to know how to do for a long time.
Thank you.

Just about to watch this video, I'm already loving your enthusiasm!

Perfect & clear explanation (way better than my textbook/professor)! Your video was very helpful in studying for my final tomorrow. Thank you!

Row-reduction, the universal remedy of Linear Algbra xD.

You made me smile. your quirkiness already got my attention

I really love your videos they are always thorough and entertaining! You're amazing and so helpful for many of my math courses! thank you!!!

The vid was super informative and helpful, thanks a lot

Man, you are my God. It gets a little over my high-school tiny brain but it's just fj and.

I don’t understand the reasoning behind why you chose each operation in the sequence you chose it in

[rohunse]

First again!
Thank you for these videos

You just gave me the idea of trying to solve cayley hamilton using row reduction instead of cof matrices. Ill update if I dont die.

From multilinear alternating form come these properties

5 - 2 equal 3 not - 3
the rest of the video is amazing thank you ; )

I'm just confused why does flipping rows factor negative one out?

[tortillapls]

does 1:16 apply even for reduction of matrixes that arent being taken the determinant of? Meaning, if devide a row with a random number must I always put said number outside the matrix to multiply eventually with the matrix??

Dr peyam, Does these rules apply when calculating the determinant of a blocked matrix.

I hate maths so much and I'm literally on the verge of crying. but I love this guy he's so cute x
