I swear to Celestia I know row operations but every time I try I get a basic operation wrong and it all falls apart. I'm literally running out of paper and hope. That side, great lesion! video and audio is high quality, you speak clearly and your way of showing the steps is rly g00d.

this is probably the best tutorial video on how to find the inverse of a matrix using elementary transformations. everything has been explained very thoroughly. ty sir!

You just have to love it when you google a math video and this guy pops up. What a bloody legend :)

Easier start: Swap rows 1 and 3 of the augmented matrix. Now you have a 1 in the upper left corner. Doesn’t matter that the identity portion on the right is out-of-order; you’re gonna change it anyway.

You saved much time for me before the midterm exam .thank you from Egypt

Guys like yourself and many others on you tube make learning possible if people struggle with a certain concept and do not pick it up when first explained by a teacher. Thank you

I like the way you teach linear Algebra for sure you have helped me alot

I'm really diggin this paper cut-out method of teaching!

Thank you for making this much easier to learn

That...was great! Thanks so much. 1st time here...looking fwd to your other videos. Also : great 'fun', enthusiastic presence...watching this just after rtn from work...feel engaged again...which fir me after getting home is always a problem. Ty from South Africa...

this is the most infuriating topic so far. Any simple mistake can destroy your entire answer...

Thinking about using row operations to invert 3x3 matrices is enjoyable, just like a big old chocolate ice cream cone! But seriously, this was a fine explanation and it's a good deal clearer now. So much appreciation.

Excellent lecture sir. Much appreciated

Thanks so much for this video. I have had a very tough time to understand this because I am taught by a Korean Teacher in class. You may know how some Korean pronounce words in English. I have never got low marks (4/10) on quiz before. I hope this would help me to get better scores next time since I understand this well which relates to the next lesson ( Rank ).

Sir can we use it on finding any type of inverse matrix plizz reply

Just to clarify. This finds the Left inverse Matrix, to find the right inverse matrix, you'd do the same thing, but switching the sides correct? I always get mixed up with which side gives which Matrix, but I know that since AB=/=BA, A^-R=/=A^-L where A^-r is the right matrix, and A^-L is the left inverse matrix namely A^-L*A=I and AA^-R=I

Thank you very much Sir. That was very helpful.

thank u so much sir u explained so easy and effective once again thank u.

Well explained sir. Thank you. :-)

Ok, I'm having some trouble grasping what this actually means. If you have a system in augmented matrix form like this: [ a b | 1 ] [ c d | 1 ] I know that corresponds to the system: ax + by = x cx + dy = y But what does this correspond to? [ a b | 1 0 ] [ c d | 0 1 ] Is it the same thing?

Thank you for such a video, confusion cleared... Thank you

It's so much easier to compute the adjunct matrix via the method of cofactors, and then multiply by 1 over the determinant. It's so much easier. Takes away all the guessing.

@walterpu8357

row reduction is faster if have enough practice. Cofactor is easier but it requires more calculation

Please explain me @ 7:32 when you did 2R2+R3 then you should apply this on newly formed matrics i.e. 1 | 0 | 1 0 | 1 | 0 But you applied on 2 | 0 | 2 0 | 2 | 0

every step he made was ok. All operations become from a previous matrix.

Can someone tell me what can be the reason why when I try to check if the result is indeed the inverse matrix it always doesn’t work. What can I be doing wrong

Thanks a lot! Trying to keep up with my math, several years later...

thanks for teaching me

Thank you very much

Thankss sirr~finally i understand itt

Sir I have a difficulty understanding this video. If the row operations are swap, scale and pivot why didnt you use swap operation at first. Also If I multiply Row2 by 2 and add it to row 1 should row 1 change. But Row1 is kept same until 5:0. Hope you can help

For the last step, what if we take R3 - R1. Will answer be different?

@lorenzflores5056

6 жыл бұрын

Mois Siow R3-R1 would disrupt the identity matrix we are trying to create which has the first row of 1 0 0. R3-R1 would give us -1 0 1

Another way to start: create the augmented matrix, and then switch rows 1 and 3. Now you have a 1 in the upper left corner without any row operations.

good but i do believe it is better to find the leading ones straight away and just deal with the fractions just how we are taught, and i would imagine most others

But why do we need inverses ?
