Yes. And it is amazing. I have a subscription to Coursera. But nobody there can explain it as understandable as this simple school black and whiteboard. So I am asking myself why I am paying the money to them. However, I am just a beginner and will do the course of 29 lections about integrals later. I still do not understand what this all has to do with Python and Programming overall, because I am not a programmer, but I do feel the beauty of mathematics. And it is good that in the internet era we all have access to those materials. Even someone, who has not studied math in university (it was my hidden dream, as also a study of physics, but I have studied history and philosophy). I do believe, that this knowledge is also important to systemize the understanding of every Data you use in your job. Especially, if it has something to do with computers. I do think, that this interest of mine came from the fact that I am surrounded by engineers and I have gotten addicted to mathematical logic.=)
because your teacher suppose u learn for exam and he don't tell u the meaning of determinant If u want to learn I recommend a book "linear algebra and its application"
Some lecturers are very talented academics, but can not explain the simplest things. It is ok. Of course, if you are not in a situation where the work has to be done right now.
An easier way to find the determinant of a 3x3 matrix would be to rewrite the matrix in terms of a 3x5 matrix where the two added columns are simply the a and b element repeated. You then take the summation of the product of the 3 primary diagonals from upper left to lower right and subtract the summation of the product of the 3 primary diagonals from upper right to lower left. Your new matrix would look something like, a1 b1 c1 a1 b1 a2 b2 c2 a2 b2 a3 b3 c3 a3 b3 And finally the resulting algorithm, ([a1*b2*c3]+[b1*c2*a3]+[c1*a2*b3]) - ([b1*a2*c3]+[a1*c2*b3]+[c1*b2*a3]) Would yield the desired determinant
MR. Organic Chemistry Tutor, thank you for showing students How to Find the Determinant of a 3X3 Matrix. There is whole chapter on Determinants in Linear Algebra.
I really enjoyed this😊 I actually know nothing about Matrixes But now...i can say I'm good🎉🎉❤ Thanks so much❤😊 You really helped me to perform well in my Assignment❤
Hi man, you damn Good can you please make a video on Factorisation, Simplifying, proper fraction and improper fraction or if you already have them please share the link. am doing Advance Math and am finding it difficult because am struggling with factorization and others.
For examination your school home work this method is ok however if the matrix in 5X5 you cannot solve it with this rule you should put the matrix into upper triangular form and multiply all diagonal elemnt

@@miriamputter7059 you have to know linear algebra if you want to be hireable with programming with python. numpy is all matrices

Hy cute girl
I’m in 8th grade bro
Simplified it, demystified it AND gave the formula. Brilliant, thank you!
Thanks, literally took me few minutes to understand the walk-through. I remember when my lecturer tried to teach us this, wasn't as easy to follow.

Would yield the desired determinant
this looks a lot easier! i haven't tried it yet but i gave you an upvote
edit: can confirm, this works!
I know this method it was also told by our teacher (in india)
@@FelixMarshFTW indeed. This only works for a 3x3 matrix though
@@FelixMarshFTW doesn't work for higher order matrices it's called saras method btw
@@FelixMarshFTW that's how my math teacher does it
Your teaching have made me feel easy in determinant chapter
MR. Organic Chemistry Tutor, thank you for showing students How to Find the Determinant of a 3X3 Matrix. There is whole chapter on Determinants in Linear Algebra.
You make it simple for us to understand fully.. Thanks and God bless you.. Please do more and send it to TH-cam..
The lecturer taught me this and I wasn't able to follow,,,thank you so much you have assisted me❤❤❤❤
This guy just helped me in my 30 question matrix homework 😊😊😊😊😊😊
Thank you.
I've only watched two videos thus far, and I liked them.
Hopefully it will help me in the future.

I really enjoyed this😊
I actually know nothing about Matrixes
But now...i can say
I'm good🎉🎉❤
Thanks so much❤😊
You really helped me to perform well in my Assignment❤
really helpful and understandable, thank you 🙏
Your channel is so world classplz we and my frndz are all following plz clear aur calculus parts and concepts
Thanks so much, it's a quick and a clear way to understand
You totally made me understood this❤💖✨
He done great job 👏 excellent sir
thank you ❤
Thank you sooooooooo much i understood this thing now only😅
Thank you very much
You should make a video about laplace expansion for matrices larger than 3x3
Nice explanation sir..😊❤
Good work brio plz make video on limits and differentiation
Thank you so much, sir😍😊😘!
thnku so much 🙏
Genius sir....
Can you make a tutorial on irrational functions pls?
Thanks ❤
nice explanation sir.tq
Good keep it up
Thank you so much sir
Oof my favourite TH-camr ngl
Thank you sooooo much
Plz expain how to find Determinant of 4x4 matrix
I’d assume it’s the same way. Just way more math
Thanks
Thank you
Do we do just the first row of the matrix? Or it depends
What type of writing tablet do you use for these lessons?
Thanks bro
Thanks!
quite appreciated
What's the guarantee that what u have just said in this video is absolutely correct
Maybe because this method is proven in mathematics
How about you solve these yourself instead of asking stupid questions
Hi man, you damn Good can you please make a video on Factorisation, Simplifying, proper fraction and improper fraction or if you already have them please share the link. am doing Advance Math and am finding it difficult because am struggling with factorization and others.
For examination your school home work this method is ok however if the matrix in 5X5 you cannot solve it with this rule
you should put the matrix into upper triangular form and multiply all diagonal elemnt
There is a far easier way of finding the determinant of a 3x3. I can show you a link if you're interested and you could make another video.
arthur karim Can i see the link?
@@pspmaster2071 th-cam.com/video/V3e7m-qFDFU/w-d-xo.html
This will take maybe one or two problems to get used to. Super efficient.
Tq sir❤
when you email the teacher the day before the test asking if you can use a calculator and he says no and i proceed straight to this video.
Is 2×3 and 2x3 possible?
Check -5*-6..the 3rd 2*2 matrix.
that is more simpler than my teacher
it's -737 actually but thanks for the concept
i love you
It's not necessary to have zero answer of this rule....
Nice
Where has the-3 come from
We take the first row
nice
Tu as fais une faute
-6 x 8 =-48
short and consince
-3 please explain 😅
There is a pattern, the odd number placement will get negative sign in front of it
Its alternating signs like
+-+
-+-
+-+
First
Muthew scnnn 💋💋💋💋
theres a much easier method to do this...
Share with us plzz
Thank you a lot
Thanks
