I just wanna say, one of my friends recommend your videos to me. Even in high school, my calculus teacher would tell me that it’s very rare to find a linear algebra teacher that teaches it well, but you managed to do just that even without the use of too many visual aids. I will be recommending your channel to anyone I know taking the course. :)
This is the best channel that I've been discovered in UA-cam! I completely love the way you explained the way to do the problem, and then going to practice question right after! Thank you, Thank you, Thank you!
can the formula also be (λI - A)x = 0 ? My textbook gives me this formula but in the video we use (A - λI)x = 0. Why do you write it like this in the video?
@@SawFinMath The amount of work you put into all of your videos, you're 100% right to monetize. Some people have become millionaire celebrities on UA-cam. I love your videos. This series prepares me for Mathematical Foundations of Machine Learning in Fall '22 semester.
I never made an A on a college math test, only ever got around a 70-85. until i started watching your videos! Got a 92 on my last one! Thank you!

15:46 I thought basis only consisted of independent columns from the original matrix?
thank you so much, your videos are very helpful and helped me pass my college linear algebra class thank you , and keeping doing what you do.
will you be making more videos for rest of the sections in the book? your lectures are amazing
AT 15:21 I though it should be -1/2 for x2 and -3 for x3. Why 1/2 and 3?
i want 5.3 5.4 exercise videos of this book?
12:18 i thought each column needed a pivot in order to form a basis, im confused why its a basis when a free variable exists
I'm not sure, but I think u made a mistake in 7:40 if it's row-echelon it should have been -1 and 3 in the first row.
It looks correct to me. I believe she did -1R1 --> R1. Then R1+R2 --> R2.
same i was also stuck there.. damn you will see it after 2 years! good luck man
can you tell us the book that you are referring to in your videos, your videos are great 😀
David Lay, Linear Algebra and It's Applications
what textbook is used for this course?
can the formula also be (λI - A)x = 0 ? My textbook gives me this formula but in the video we use (A - λI)x = 0. Why do you write it like this in the video?
Yeah, it's the same thing
good job
Why would the identity matrix be a trivial solution? I thought the zero matrix was a trivial solution.
Because it will give x1 = x2= x3 =0 (which is trivial i.e useless solution). Zero matrix will give 0 = 0 i.e no solution.
whats the reason for 7:43 ?
why the 2 steps ?
you just subtract, R2=R1-R2
I am confused @ 7:38, what is the math behind that?
Determinant row operation (R2= R2 - R1) and so on....

I am not kidding... Too many ads
You are welcome to find a UA-cam creator that doesn't monetize their videos.
