0:13 : 2 important reasons for this discussion 1:04 : How to approach the problem 4:32 : IMPORTANT : Infinite many ways to capture the line 4:52 : IMPORTANT point : looking for set of vectors
adding the vectors as described in the addition video using tip to tail gives a much different angle than the one displayed. why? did you just not draw it exact?
@@MathTheBeautiful sorry no I'm wrong it's accurate you explained it later (when alpha is zero, when its one, etc thats when i understood). I thought the additive vector was supposed to be parallel but it was just an equation to get all the points possible on the line you drew.
Go to LEM.MA/LA for videos, exercises, and to ask us questions directly.

totally new insight to me, on in the hindsight, on null spaces and in general on solution to system of linear systems. thanks !
Amazing freehand draw of the line! And lovely video, thx
The secret to is look at the destination.
thank you so much for these wonderfull lecturs, truely inspiring, thanks to you snd gilbert strsng I love more LA
add 3blue1brown to that list and you have the trifecta of linear algebra
Thank you sir.
Glad you found it helpful!
Why without subtitles?(((
Would've been more complete, as a visualisation exercise, to have drawn in the vectors b + @a etc
Awesome the ah ha moment was at 4:34

Yes, if there's any inconsistency it's due to the accuracy of the drawing.

Please accept my apologies with regard to the lack of subtitles. I just don't have the bandwidth to do this.
