When I first took a linear algebra class, I think it was around the time we got to the null space that I started to get rather confused. Thanks for putting together these lectures to help us learn (and re-learn) the material and clear up our misunderstandings!
thank you so much. this man is genius. after watching this lecture i came to conclusion that i am not dumb but the way of profs teaching is dumb because this man right here makes everything so easy and its a wonderful feeling being able to understand what in the world is actually going on.
Amazing video! Its the first time I have someone explain math in the same way I think. First I want to understand the computation, explain what the concepts being addressed in each step are, and then tie it all together by linking it all! In class we are usually taught the concepts and then computation, and its hard for me to make the connection. Thank you so much!
deeply appreciate your efforts. step by step thorough explanation helps understand the concept well. thank you so much😊 (by this point, i wish all my math syllabus had videos by you)
appreciate so much! i had hard time to understand AX = 0, luckily i found this precious lecture so that makes me go to next step! thank you again for sharing this wonderful video.
i am not understood how 1st roe elements changed if i am going proper echelon form your matrix is differnt than me also i amnot getting last row last element is not getting zero
Are you ever planning to do advanced linear algebra course? These videos are nice to review some concepts but would be better if you are able to do more rigorous L.A. concepts.
I would like to, but need to make more basic videos first that are relevant to more people to pay for the production of those more niche courses. As soon as a lot of my basic videos break into the pre-algebra search rankings, I’ll be able to make a lot more advanced stuff!
Do you mean a linear algebra playlist? I already have one, it is linked in the description. However it is currently unlisted - meaning you can only access it with the link. This is just because it’s very small right now, and I don’t want to clutter my playlist space with small playlists, but it will be in the description for all my Lin alg videos, and will be public when it has more content! Let me know if you have any topic requests and thanks a lot for watching!
When we solved for the leading variables in the preceding step we found restrictions on x1 and x3. We found no restrictions on x2, x4, and x5. So when I consider the column vector [ x1, x2, x3, x4, x5 ], what is x1? Well, from our work we found x1 = 2x2 + x4 - 3x5. What about x2? Well, x2 has no restriction, so all we can say is x2=x2. If we had found x2=0, we would have written that, but we found no restriction on x2 nor the other free variables x4 and x5. Does that help?

Detailed, to-the-point videos in a modern reaction vid type format? Super creative!
Thank you!

took me just a few mins to digest the concept and now i feel confident, most thanks to you!!
Awesome! Thanks for watching!
This was the single most helpful math video I have ever watched. Thank you.
So glad to hear that - thanks for watching!
Nullspace was melting my brain. Thank you so much!

I have an exam tm.You’re videos are a life saver.
Good luck!
How'd your exam go?
deeply appreciate your efforts. step by step thorough explanation helps understand the concept well. thank you so much😊 (by this point, i wish all my math syllabus had videos by you)
So glad to help - thanks for watching! I hope to have full playlists on all undergrad math courses in due time!
You explain linear algebra a million times better than my professor, thanks man!
Happy to help!
What a lovely video. There's a smooth progression from step to step without our time being wasted
Thank you!
It's very informative for my exams, thanks man
Glad to help, thanks for watching and good luck!
Thank you very much
Iam at engineering University ❤
Thanks, it was really easy to understand❤
Thanks for watching!
appreciate so much! i had hard time to understand AX = 0, luckily i found this precious lecture so that makes me go to next step! thank you again for sharing this wonderful video.
Glad it helped!
You may not the almight professor that masters every subject, but I appreciate such effort dedicated into explaining it so smoothly. Please keep it up
So kind of you to do these very educational videos, thank you.
Thank you!
Great explanation! Now I feel a bit more secure in my math exam tomorrow!
Glad it helped!
How'd the rest of your linear algebra class go?
please make videos on limits and continuity in matric space also on their properties
Thank-you so much you helped me in real analysis and now here also ❤❤❤❤❤❤❤❤
May God bless you !
Looking good, bro. Good review. Doing some statistics theory proofs and oof they rely hard on this stuff. Thanks!
Glad to help - good luck!
Thank you Sir for your great video . Your explanation is very clear !😀
i am not understood how 1st roe elements changed if i am going proper echelon form your matrix is differnt than me also i amnot getting last row last element is not getting zero
Super clear explanation from the definition to how to do it. Thank you.
Glad it was clear, thanks for watching!
thank you, your explanation is very clear, and this video is very helpfull, all your videos are great
Thanks so much!
Leading variables correspond to those positions which appear first in the reduced row echelon form
love this, thank you!
Thank you!
That helped out a lot! Thanks!
very useful👍
Is it safe to say that the number of free variables is the null space?

@@WrathofMath I understand. Good luck!
Thank you
Thank you for watching!
Great vid much thanks!
Glad to help, thanks for watching! Much more linear algebra on the way!
Wow,awesome thank you
Glad to help, thanks for watching!
If possible please make Playlist separately ,will be helpful to find videos 😊

well done.
When you were forming the equation, X2 was Zero(0x2) but now in the matrix it is one(x2), how?
I'm not sure what you mean, do you have a timestamp/can you be more specific?
2 pivots and 5 colums. 5-2= 3
Does this holds for every example?
Any concept behind your generalization?
3:57 why write x2,x4 andx5 and not leave them as 0, in accordance with the equations above (in blue)?
When we solved for the leading variables in the preceding step we found restrictions on x1 and x3. We found no restrictions on x2, x4, and x5. So when I consider the column vector [ x1, x2, x3, x4, x5 ], what is x1? Well, from our work we found x1 = 2x2 + x4 - 3x5. What about x2? Well, x2 has no restriction, so all we can say is x2=x2. If we had found x2=0, we would have written that, but we found no restriction on x2 nor the other free variables x4 and x5. Does that help?
@@WrathofMath yes, thank you.
may i know why x2, x4 and x5 are free variables?
They don’t have leading 1s, X1 and X2 are not free since they have leading 1s
Appreciated 👌
Happy to help!
thanks
You are welcome, thanks for watching!
so basically Null space is = to how many free spaces (or free variables, doesn't matter how you say it) there are
I think You'r RREF is wrong. Please cionfirm it mine's comes different????🤔🤔🤔🤔🤔🤔🤔
😋😋😋
made it too complicated useless video
