I am a Junior in college and every time I have to look something up this guy pops up. He always knows what he is doing.

thank you so much! very clear and easy to follow :)

You are welcome. Glad you found our videos. 🙂

[@MdAbdullah-uf4sz]

i watched 20 more videos to understand Echleon form & Determinants. this is the one video , I understand both term.

[@MichelvanBiezen]

Great! Glad you found our videos! 🙂

​@@MichelvanBiezen sir, i have a question if i make a r3 --> -1/10r2 + r3, should i multiply it with -10 in the last answer?

@@MichelvanBiezen wonderful stuff. Was fully erect throughout. cheers

who is wrriter of this book ??//?

[@prox3667]

Were we not supposed to divide by 5 too considering the third row operation ?

[@EliCarlton]

Nope! only if you multiply/divide through a row, if you are adding/subtracting a multiple of one row to another then you dont need to change your determinant

[@samiafzal7023]

Brilliant 🤩

[@MichelvanBiezen]

Glad you like it.

[@Amotivation-gl5oy]

Is it row echelon to row reduction method

[@MichelvanBiezen]

Different names for the same thing. 🙂

[@max_automation1090]

Hawwwwwwt damn this is a great video!

[@videocorner3305]

Why did he multiplied by 4 at last step??

[@MichelvanBiezen]

Note how the diagonal elements are multiplied by the negative values of the off diagonal elements in the first column.

How many bow ties does Michel have? I've never seen him wear the same one twice, and I have watched lots of his videos.
