Example of Basis for a Span

Показать описание

Linear Algebra: Find a basis for the span of the vectors {[1 2 3], [1 1 0], [5 8 9], [3 3 0]}. We present two approaches, one computational and one direct.

Thanks for explaining the process in the first 30 seconds. That's all I wanted to know haha.

Oh my god you are just amazing. I know how to work through finding the basis but have no idea why this works, so thank you for explaining the rationale behind it.

Such a nice, complete channel. Congratulations, sir.

You explain this very well, thanks! You look like you're a CO teaching linear algebra to a class of inmates though... Using the billy club as a board pointer just to make sure they don't get any ideas.

Your welcome, and thanks! I'm probably more arselike in front of a regular class, but here you can work magic with editing and multiple takes.

Your welcome, and thanks for the kind words!

@djd259th You're welcome, and thanks again for the comment! I've taught some rough classes, but none that rough. :) - Bob

Thanks! Just a little advice - the main problem for me when I try to find help for math class on the internet is translating different definitions to my native language. I suggest you make a way for people to recognize the English definition easier, like an annotation to the video explaining the term, for example.

You're welcome! Understood, but it's a matter of resources. I barely have time to bleed these days.

MathDoctorBob

Still an amazing explanation. Thank you

jonnytheduck

And I got the question right as well. That's a bonus. Thank you kindly =)

stev

Amazing! Thanks so much! All your explanations are incredible

scikud

Thanks a lot! ^^ now i'm not confused anymore :)

How does column two of the RREF form a pivot column when the column consists of vector [1;1;0].... That doesn't make sense to me.

@killakiz06 Thanks! Good luck with finals. - Bob

Can you teach my linear algebra class?

@SmOkEyJoE2323 I love the classroom, but I do more good out here. - Bob
