Basis and dimension

[@nickoliveira5938]

Wow ive sat through 6 hours of lectures for something you took 6 minutes to help me understand. Thank you!

[@a-factoracademy]

Not only you brother... Thanks and thank you KZbin!

[@aperson6966]

Cap but ok

[@Marawan]

It took me 8 hours of browsing through books and videos to try to understand this chapter, but you explained it in 6 minutes and I understood it immediately! Thanks so much Dr Peyam, keep it up!

[@EfeAikpokhio]

This guy is amazing his videos are quick and direct. Thank you so much, sir. I wish you nothing but the best in life.

[@woodwardscreditcard7482]

This is excellent for someone that just want to start working on problems without all the fatuige that comes with the ins and outs that text books and many lecturers bombard you with. I enjoy math but damn some people just want to make it harder than it has to be which is annoying. Thank you for this demo!

[@drpeyam]

Thank you!

[@j.j.3759]

I see you've met my professors.

[@olabayoenoch4414]

Awesooooooooommmnme... I had my initial doubts but you cleared all of them. Your attitude also makes it look very simple and believe me, it helped prepare my mind to understand. God bless you, Amen!

[@Skystrike70]

Subbed for how fast you are able to effectively get the point across, this is my second video of yours I've watched!

[@tevintitus]

The best 6mins, is it possible to make few more of these truly helpful.

[@drpeyam]

There’s a whole playlist!

[@CypherSteve]

His explanation is so great, thank you so much, Dr Peyam

[@faizanurrehman6220]

Seriously i hate to Analyze about bases and its relationship with dim. But in this video i can easily understand about it, thanks allot please make more videos on bases and related things

[@lightspd714]

You always give the best explanations!

[@antoniobrites5431]

Thank you so much for your class. I just didn't understand why we went back to the original matrix to pick the two vectors for the basis, instead of just using the ones we came up with in row reduction. (1,0,0) and (-3,1,0)

[@drpeyam]

Because row reduction destroys span but preserves LI

[@rishipatel2670]

Thank you Dr. Peyam, I have a final coming up this Thursday and this video cleared up so much confusion!

[@Spacexioms]

Finally understand what a basis is. A basis can be spanned to form a linear combination. Find the basis can help us find the the vectors which can be spanned into other vectors and this helps us get rid of information that is not needed with the original matrix A. Also, help find the dimension.

[@3bananasforaeuro152]

Thank you for saving me 6 hours before final a crown here for you my king 👑

[@drpeyam]

My pleasure 😁

[@volly4260]

Honestly most of the comments are about how this helped a lot of people and it is very briefly and well explained, well , i will add one more to those type of comments :D ty so much professor.

[@drpeyam]

Thanks so much!!!

[@mamadetaslimtorabally7363]

What a fantastic explanation! Really helpful Dr Peyam. Thanks so much.

[@krishnaarjun6834]

Amazing, short, very useful, full-energy-packed session 👏 👍

[@thespicegirlsful]

Best explanation got it immediately, thank you Dr Peyam!

[@doodelay]

For a long time I found row reduction a colossal pain and a waste of time. But now I see that reducing a matrix gives you a GIANT amount of information all at once. So it's very much worth the time investment!

[@plopterjones2147]

Lol, I had him at TAMU and his video just showed up while looking for linear algebra stuff. Miss you Dr. Peyam!!!

[@drpeyam]

So cooool!!!

[@ShivShankar000]

just amazing. I understood how to find basis and dimension.

[@Linn201]

Oh!! Thank you so much. Much obliged for your help ❤

[@typo691]

The thumbnail quote is wrong, should be "I'm all about that basis"

[@blackspygamer8500]

R should be roll anna maata kinda padi dorlali😂😂

[@MuhammadMuneer-rh1by]

when should we use ref vs rref when finding basis / lin independence / wether it spans or not

[@danadallal6314]

i love this guy's energy

[@bygrace6578]

Wooow!!! I love it and I will recommend it to my colleagues.

[@asn9329]

Why I Can't write [1 -3 -4 ] and [0 1 3] as basis of this subspace?

[@jojo_099-4]

wait so now, i don't have to go through checking on the linearly independence and the spans? i mean our prof said that we have to check if the matrix is L.I and it spans the V. so should i just skip these two steps and find the basis of column space and that's it? would it be considered correct answer? +thanks for the video by the way!!

[@dvdz1180]

thank you doctor for this masterpiece I really just wonder what the diff between is make the set in the column and the row space and thank you again for this masterpiece.

[@gopalsutrave]

nice explanation sir... very good

[@coldplayofdoom8908]

You‘re actually nuts, how have I not found you earlier

[@andresbarmet1227]

You are really awesome and a very cool teacher 🙏🏾🙏🏾

Thank you!! You helped me a lot

[@sanghyeonchang2600]

So is the Rank of matrix and Dimension of matrix same ?

[@akashsonawane3310]

Nice explanation...... Sir🙏🙏🙏

[@ousmanfitness8132]

would you please be able to explain to me why it matters if I make a matrix with each vector as a colour vs each vector as a row?

[@BlijVrouw]

Thank you, Dr Peyam!

[@UNCLESAM-TV]

Thank you very much for helping me Sir

My pleasure!

[@RaidenEdits]

Thank you very much for the explanation!!

[@glenncouto]

Can you make a video on intersection and union of column spaces ?

[@drpeyam]

I made one on intersection and union of vector spaces

[@glenncouto]

@drpeyam Can you share which video it is ?

[@drpeyam]

I think it’s called union of vector spaces

[@glenncouto]

@@drpeyam Let 𝐴 = [ 1 2 1 3 ] and 𝐵 = [ 1 0 2 1 ]. Find a basis for the subspace 𝐶𝑜𝑙(𝐴) ⋂ 𝐶𝑜𝑙(𝐵) and hence determine its dimension. This is my question. Not sure how to go about it. I know to find the colum space individually for each vector.

[@ЕгорШевяков-з8м]

so touching for an excellent video

[@anshsingh2783]

Your lectures are 👍 good

[@olasunkanmiadeniji8838]

Sir, can you please tell me the answer of the question below: Let V be the vector space of all {2,4} matrices i) Determine the dimension of V ii) Determine the basis of V Thanks as you answer !

[@ijazkhanniazi800]

I want to ask Same questions

[@krishnaarjun6834]

Wdym by {2,4} matrices?

[@bongamthokozisi2755]

wow interesting thank you sir can you please do for the complex numbers basis and dimension

[@drpeyam]

Check out matrix of rotation

[@silversky216]

i wish i could have a professor this sweet

[@abtinjaberi2927]

very nice explanation

[@rockyjoe3817]

Hmmm I saw Gaussian Elimination and Echelon form and Reduced Echelon form but when doing linear systems in matrix form why do we sometime put or not put 0's filling the columns at the last row?

[@Skystrike70]

Google REF vs RREF. It's 2 different forms, and RREF is the one with zeroes and has more uses than plain REF.

[@ADS090]
