Taking Linear Algebra right now in Uni. I do not understand the way my professor teaches but you explain it so clearly, hopefully, I can apply what I've learned from you to my exams. Thank you so much!!
I've been having a hard time in my class. I just finished the first three videos and understand linear algebra easier to understand especially since I have my first test today. Thank you so much!!!
I didn’t want to pay for school and I learn better on my own, plus math comes naturally for me, so I decided to use these lectures to teach myself the subject. This is the only math class I’m missing for the math section for taking a FE exam thank you!
It reminds me of Algebra II in high school though this course is probably significantly harder than Algebra II. You do a very good job of it explaining the material.
I'm writing a test in two days and I didn't understand my lecturer but your videos helped me a lot and I like the fact that they're very shot compared to a 50 min lecture. Thank you very much.
Great playlist! Completely underrated...Not sure if anyone struggled with this but years ago I couldn't understand what # to choose when multiplying the 2nd equation... So maybe this will help someone who doesn't understand how to come up with that #. I don't remember hearing how he came up with the number he used (-2) to multiply the 2nd equation by...so if you need things broken down as I did once... From my understanding, you "multiply each equation by a suitable number so that the two equations have the same leading coefficient"....for example -2 (0.5) = -x and so on and then continue solving
This video is really helpful! I am taking linear algebra this upcoming semester so I'm brushing up on it beforehand. I was wondering while at 17:08, is there a reason for not swapping R2 and R3? My first thought was to do this because the current R3 (0,1,1,0) is already solved in triangular form if it is swapped with R2? Thanks again for this series, I'm sure it will be a life saver !!
Glad you're enjoying the videos. That would be an unnecessary step since you still have to do the same replacement operation, just with R2 instead of R3.
Hello, for the last example you provided, instead of R3 +1/2R2 could you simply do 2R3+R2 in which you would get x3= 2/7, x2= -2/7, x1= 29/7 as your ordered triple (29/7,-2/7,2/7)

Thanks for amazing lessons! Your videos deserve 1M views

I having been studying this subject for 'pleasure' for a while but only now understand it! The clearest explanations I have ever seen.

thank you!
It’s so beautiful, man!😮😍 It’s like an unsolvable puzzle at the beginning but then all the puzzle pieces fit together perfectly at the end.

I haven't even finished yet but I feel so comfortable listening to this. It is amazing.
You are Adding value in lives, God bless you
Please never stop making your amazing videos!
Youre a life saver

Best Linear Algebra videos. Thank you so much!

What a lovely teacher,
Now I can say, I love maths
God bless you Sir for such an amazing video
I haven't words to appreciate sir....
Thank you so much, Sir
Super ❤

i was wondering the same exact thing! did you ever figure it out?
I did it using your method originally, where you multiply R3 by 2 and add it to R2, but got the same answers as he did. I think it should work!
Why did we multiply -2 in the elimination method?
13:06 I don't understand this in the bubble:
4 -12 16 -16
How did you get that?
I multiplied Row 1 by 4.
@@HamblinMath Thanks, sir
appreciate it
Thanks for the video
This course help for Quantum mechanics? Or i should follow Gilbert?
Hi James, I'm enjoying these videos a lot. Any good resource for practice problems? Thanks.
Why did you use
X(-2) to multiply the second equation, can’t you use other numbers like 3 or 4 ?
When?
@@gradientO at the starting of the first equation
@@gradientO 0.5x-3y=11
Wow thank you so much!!
are these lectures associated to a book by any chance?
on the last problem why did u use 1/2 instead of 3 or 2, just as u did in the previous example. because there is no 1/2 in the matrix .
Thanks
this is actually Gaussian elimination
? right ??
God bless you
thank you sir...
Tqsm sir ;)
thanks man
Thank u so much
