Thank you, thank you, thank you so much! I got a bit stuck on my linear algebra homework but you helped me get through it! Thanks again, and I'll make sure to reference your channel for other stuff!
When I first heard you go on small tangents about how "we can also calculate the *xyz* and the *abc*" I was kinda irritated, not gonna lie, but it quickly grew on me, you are a natural, keep up the great work!
You do row operations until you get the matrix into reduced row echelon form. You can search it up to understand it. Also, I just found it: th-cam.com/video/biW3S9EdE4w/w-d-xo.html
I gathered everything you said in this video by just looking at the thumbnail. Try explaining why you are doing what you are doing otherwise the lesson is useless

Very simple explanation, thanks a lot!
You're welcome!! The full playlist is here: engineer4free.com/linear-algebra and there are more tutorials on matrices in videos 35-44 👍
THANK YOU!!! this made no sense in class and i immediately understood while watching your video!

Thanks this was very helpful and concise!
im gonna cry man. how did you make it so easy when everyone else ran circles around the actual topic.....
yeah bro haha I donno, but glad it helped =)
Thanks for making this video and it's really helpful 👍
You’re welcome!!! Thanks for watching 🙃
I like how you write your 5's. Efficient
I never once thought about how I write them 😏
Like a computer.
90% of what you find when looking for "how to find the nullspace of A": HOW TO FIND A *BASIS* FOR THE NULLSPACE
Cause it's the same process
Bhai nullspace will only exist if the system of equations is consistent or nonsingular. The idea of nullspace is nice for mostly consistent systems.
Awesome explanation
thank you, now I can do my homework :))
Thanks for making the video
Thanks man❤️
shit was fire! thanks so much for the help
this guy knows what hes talking about
hahaha thanks dowg
thank you very much
You are welcome!
why can you ignore the x3 and just make it x. Is it cause its just some value for the variable and it doesn't matter what you write it as?
yes! exactly :)
thank you thank yi thank yiu
I am wondering to know,about how many times we need to do the tow operation.
You do row operations until you get the matrix into reduced row echelon form.
You can search it up to understand it.
Also, I just found it:

Thanks 1 hr remaining to the exam and im learning it lol
Hope it went well!!
@@Engineer4Free It went rlly well but i could do better you know xd
why is the 0.5 not changing to 0 for the last step of the reduced row echelom?
Is column set with pivot variable is linearly independent ?
so generally the independent variables span the null space right?, then the dimension of the null space will be no of independent variables
how does this relate to span of A & B without given an initial B matrix D;
Why 2x?
I love you
what's the dimension of the null space of the matrix please
4:16 Why is x_3 set to x_3? Why is it by itself?
its a free variable so it can be anything
NO I MEAN NULL IN MINECRAFT
Lulz ⛏️
Oh my god okay so you just solve Ax=0 and that's it? Jesus why don't people say that in the start? 🙄
Yeah basically. Profs just tryna complicate your life 🤔
i think what you are doing is finding the basis of the matrix
I am not happy about watching this
