If only I had found this 3 weeks ago. Gained so much w/n the first few minutes of this video than in a 50 minute lecture. Now I just may pass my exam tomorrow after all!! Thank you sooooo much!!
thank you so much for this, I am doing this stochastic processes class and got to the Markov chains, the book is using a great deal of this material, I can't thank you enough.
Keep the linear algebra stuff coming! I don't have the class available at my school but I've been reading some books, and your videos would really help a lot!
Easy concept, just a massive pain in the ass to compute matrices by hand (especially inverses). Either way, nice video - organization and showing all your steps for problems like these is extremely helpful for those learning the material.
Thanks a lot, Patrick! Now I understand this process better. Who the heck would want to find the inverse multiplying all the elementary/elimination matrices? Doing that feels like a death sentence. Finding L--the inverse of E for A = LU--was the same as undergoing that sentence!!
Hey Patrick. I like the way that you approach this problem with putting in the values of 1 then simplifying the surroundings. Could this also be used for complicated problems as well and does it always work? Also, is there a certain formula that can be used to find the inverse matrix of a 3x3?
I was just wondering, instead of getting those fractions, isn't it possible to replace that step (the one that gave you the fractions) by -2 x R3 + R2 -> R2, which gives (0 , -1, 0 | 1 , 2 , -2 ) for row 2? And then do -1x R2 -> R2?
Why do you have to multiply 3/7 by row 3. Could we not just do 3/7+Row1 since row 3 is 1 anyways? Is there a reason that we have to mutiply by row3 before we add row 1? I guess I just figured that we would come out with the same result either way.
Sarah Buescher I think it's because if you just did 3/7 + R1, you'd have to add 3/7 to all of R1 meaning you would change the 1 that you already have on the top left to 10/7, and the 0 in the first row second column to 3/7
Good day, is the Gauss-Jordan method in finding the inverse of a matrix is applicable if you have an n x n matrix? What I mean is if you have a 4 x 4 or even higher dimensions of matrix?
THANK U SO MUCH!!!!!!! i have been watched a lot a videos how to do it method, but i didn´t catch it. So i saw this video and i was... (wtf?, that is so easy)... So... thanks again.... You have another subscriber :´)
a while back in i learned that there is a way to determine if a matrix has an inverse...will that be covered too? i kind of forgot how to do it. also can you give a real world example doesn't have to be complicated, just good enough to give the brain a reason to remember matrices. thank you.
Thanks for the video.. I understood the method from here. But one thing, I could solve it without using any fractional value.. the calculation is less cumbersome that way.

0:38 sec . you sacred the hell out of me patrick .. :D
but the topic is well learned at the end of the day (y)
same here I litteraly leaped from my chair lol
I was playing this video thru my guitar amp (how I listen to music). Needless to say, I thought it broke my amp for a second!!! :')
seriously they way u teach is totally awesome, im in love with your videos . :-) :-) :-) :-) :-) :-)
You deserve a subscription due to the detail steps of each problem you solve
I kind of love you. I just started Linear Algebra and this is so freaking helpful.
God bless you Patrick. You are the best.
u are the best...your tutorials made me got 100% on my integration test...YOU ARE THE BEST. ..
give this man a medal!
he already has a lot
+Cleo Manloloyo who is he ? where does ve work or what does he do?
I mean he needs a special one
Superb! been watching your videos since 1st year of college ! better than my teacher
all of the above, for sure. super duper useful stuff
Bro you deserve a shrine! Thank you so much this video helped a lot.
thank you so much for this, I am doing this stochastic processes class and got to the Markov chains, the book is using a great deal of this material, I can't thank you enough.
You explain this method really clearly. I am really grateful for your explanation!
Patrick a BIG THANK YOU to you. You are my favorite math teacher.
Keep the linear algebra stuff coming! I don't have the class available at my school but I've been reading some books, and your videos would really help a lot!
Just wanted to drop by and say thanks.
Thanks! :)
And your tutorials are super helpful.
You are great. The way you teach very professional
Thanks a lot for uploading this video. You helped me to prepare myself for a test.
You approached this really well, Patrick! I like the method you use.
Awesome!!! U really make sure we understand each and every concept that u teach. Excellent. Thank u so much...
i will try my best :)

You make my life so easy, You are the best. Thank you!
i am sooo happy i found this vids thanks alot
this is totally helping me in my linear algebra class. thanks!
Thanks so much, your videos are the best and just swing it once it is always easy to recall it. Good job!
Thanks for that lucid explanation. Succinct and to the point.
ahhh this video helps me understand this so much better, thanks dude
Thanks a lot, Patrick!
Now I understand this process better. Who the heck would want to find the inverse multiplying all the elementary/elimination matrices? Doing that feels like a death sentence. Finding L--the inverse of E for A = LU--was the same as undergoing that sentence!!
I really owe my engineering degree to you. Thanks a bunch :)
thanks a brunch
It's totally crystal clear to me,,,,, Thankyou
Hey Patrick. I like the way that you approach this problem with putting in the values of 1 then simplifying the surroundings. Could this also be used for complicated problems as well and does it always work? Also, is there a certain formula that can be used to find the inverse matrix of a 3x3?
Thank you so much. I took Math 1 at Uni and my teacher is just bad at teaching. Ofc my exam is tomorrow 😅 wish me luck y'all.
Thanks, really helped me figure out this stuff, no thanks to my lecturer's abstract notes...
At 4:33, why didn't you just R2 - 2*R3 = R2?
That looks much easier to me, but I want to confirm that it wont violate any rules.
+Jomon well, that can be done too! and after that you just need to multiply the second row with -1
+Jomon Lol yes, thats what I did, much easier, no rules violated
Yeah I thought the same thing
What an amazing explanation, thanks
facing this matrix for final tomorrow thanks!
We do inverse 3x3 matrices in my FP2 unit and this method rocks compared to the mess of the method we're taught!
Thanks. Just the refresher I needed.
thanks so much i watch your videos and have a much better understanding you're awesome!!
you are actually the best!!!!!!!!!!
I was just wondering, instead of getting those fractions, isn't it possible to replace that step (the one that gave you the fractions) by -2 x R3 + R2 -> R2, which gives (0 , -1, 0 | 1 , 2 , -2 ) for row 2? And then do -1x R2 -> R2?
This is the method our instructor used to show to get the inverse. I do prefer the other way you shown.
At 04:25 rather than taking fraction, you could have done "2R3-R2=R2" for making the "7 of row-2 & column-2=1". Thank you.
Why do you have to multiply 3/7 by row 3. Could we not just do 3/7+Row1 since row 3 is 1 anyways? Is there a reason that we have to mutiply by row3 before we add row 1? I guess I just figured that we would come out with the same result either way.

In a 3x3 matrice and R1 begins with a negative number; do you convert that number to a positive one first?
Good day, is the Gauss-Jordan method in finding the inverse of a matrix is applicable if you have an n x n matrix? What I mean is if you have a 4 x 4 or even higher dimensions of matrix?

i kind of forgot how to do it.
also can you give a real world example doesn't have to be complicated, just good enough to give the brain a reason to remember matrices.
thank you.
Can we multiply the row that is changing instead of the row that is unchanged?
Can this be used on all matrices or do you have to start off differently?
Thank you very much! :) Very nice explained.
thanks u r really a true genius
I thought this one is elementary row operation? Or is it just the same as Gauss-Jordan method?
Thank you so much, this is helped me a lot.
I think I can solve this type of problems in my upcomming exam in 3 hours
how about if i m not going to swap row 1 and 2, can i still got the same answer?
You make wanna do maths everyday :) impressive
Nice explanation, thanks alot :)
What if u do r2-r1 ? it gives u your new r1 or r2 ?
Thank You So much!!! Awesome teacher
thankyou so much! this really help me
if i approach the calculations by different row operations and the answer comes different is it normal? :3
how do you find out if the matrix has an inverse ?
bundle Thanks sir it was very helpful
I love u😭 u r a heroo😭
thanks alot patrick!!
Thanks for the explanation... Nice and Simple... :)
It was great !
thanks for sharing.
how to find inverse of a 2x3 matrix?
Can we see some videos on introduction to Differential Geometry?
very good and clear , thanks
Thank you so much, Sir...!
thanks man
patrick
my teacher was used inverse of matrix. and then find inverse of matrix. when after we find inverse of matrix how can we find roots
why did you use an example with fractions in an instructional video?
Thanks for the video.. I understood the method from here. But one thing, I could solve it without using any fractional value.. the calculation is less cumbersome that way.
yep, there are many ways to solve these
You should be my teacher :) good job (y)
any way a hell lotta thanks to you buddy
You're the best.
This was great, thanks for the explanations.....I hated Pre-Cal until now,..now I just don't like it...lol
no you da real mvp
Thank you. it was helpful
fucking legend man, still helpful in 2024
great effort, it's appreciated :)
how to multiply by rhs vector
Thanks for this!
thank you for your help but why are you left hadned
Because he is.
Why would you ever want to do this by hand?
helped a lot !!
Thanks Bro! really appreciate it :D :)
Thank you!!
I don't understand the purpose of this method when finding the cofactor and determinant is a much easier way to find the inverse.
hai, can u teach me how to solve when the matrix have unkwon eg [1 2 -1 3]... please
[2 -1 k 1]
[-1 1 4 0]
THANK YOU!
Can i know what is his true job?
Thanks again!
Thanks Buddy.
