@@lolatomroflsinnlos haha, I fel for it too. but with some matrix transformation, you surely can flip it in post. (in the irony of the subject, of course ;-) )
Nice video, contents about it on wikipedia is somehow unfriendly to beginner(who do not know specific signs and Einstein notation), this video helps me out!
@@yashasmsalian169 it is the easier to add the row no and column no than thinking how many permutations would be needed to get to 123 actually the -1^(row no + column no) is the traditional way to determine the sign
Please what writing tool do you use for the classes, it looks like a glass mirror, I run a high school after school tutorials and I'll like to use this
sir, i have a question, what if we use that law with larger matrices, for example 4x4?, is it possible? i'm a freshman, my question may be silly, hope you can answer, thank u so much
You compute it numerically first, it'll either be positive or negative, then depending on the number of flips, if the number of flips is even then you multiply the term with a plus (term keeps the same sign), if the number of flips is negative then you multiply the term with a minus.
Hi, Fantastic teaching. Could you please let me know what's the technology you're using to do that inverted writing? On what screen are you writing and with what software ? It's so great ! Thanks

I must express my gratitude for your outstanding explanation; it was truly exceptional.
You're writing mirror-inverted like it's nothing.
The power of software!
@@ProfJeffreyChasnov I just realized I am an idiot and you just flipped it in post.

You can use a mirror to reflect your image to the camera no software needed but I think software is better

You are good at teaching. Thanks for video and love from Turkey
Great teaching
Teaching style is very amaging,love from Bangladesh.What software do you use?
Easy way to do it is (-1)^(row no + column no)
I believe that is easier to use only on third order matrices

It's called a light board.

Yes, it is a general method.
Yea nice video, but I think this showed me that I stick to Laplace to get my Determinants ^^
Nice video so underrated
so do we compute numerically the terms and flip the signs depending on odd or even? thats how to do it? thanks fir the great video
You compute it numerically first, it'll either be positive or negative, then depending on the number of flips, if the number of flips is even then you multiply the term with a plus (term keeps the same sign), if the number of flips is negative then you multiply the term with a minus.
Similarly, first row second column element is negative because (-1)¹+² = -1
For example: first row and first column element gets a plus sign because (-1)¹+¹ = (-1)² = 1
That is not the logic he mentioned here.

he just flipped/mirrored the video with video editing
how we determine the mxm matrix where m>4 is there general formula by leibniz formula
when do you know when the sign is negative or positive ?
Don't I say in the video?
