Hello, welcome to TheTrevTutor. I'm here to help you learn your college courses in an easy, efficient manner. If you like what you see, feel free to subscribe and follow me for updates. If you have any questions, leave them below. I try to answer as many questions as possible. If something isn't quite clear or needs more explanation, I can easily make additional videos to satisfy your need for knowledge and understanding.

For "Replacement" don't you only effect the top so should't it be {(0, 0, 1)(2, 1, 0)}

[@rajatsethi]

you are right it should'nt have

[@haroonw3726]

Yes, in "replacement" only one row gets affected. The third matrix in the "replacement" example should be as such:
0 0 | 1
2 1 | 0

[@torosalvajebcn]

@@haroonw3726 but first the bottom row ha been scaled by 3.

[@atharvas4399]

haha! we r adults "we do matrices"

[@osaweseowiadolor4609]

If you're watching this replacement should have been
0 0|1
2 1|0
In the end, cause only the top row gets affected, you'll see this done at 9:36

[@rishikantism]

Its always great to watch and learn from your videos, thanks a lot

[@arseniysleptsov9217]

11:13 instead -5 there must have been -3 in row 3

[@purpose_is_empty]

It's meant to be a 5, it just looks like a 3..

[@benderbendingrodriguez8950]

can you make an Algorithm and Data Structures? i need one and i can't find anything explained in a simpler way(student here!). Your explanation are the best and i think you will explain it better!

[@WaqasAhmed-th4lo]

Kindly suggest a book for practise

[@mustafamalik4211]

To solve a system of linear equations: Find the Reduced Row Echelon Form.

[@sumantkumbar9311]

Is there any proofs that if we follow the properties you said will help us to find the solutions.

[@madmx9215]

How do I know which row should I change if the question doesn't clearly state that?

[@lucci3319]

I don't understand ur question but if u askin about row reduction(simplify matrices) than u should first start from x1( Row 1) and try to eliminate x1from other rows(by making them zero with help of R1 via row operations) ... Then try to eliminate x2, x3,.....,x(n)

[@rashedspam4852]

this this basically gauss elimination method?

[@lucci3319]

Yeahhh

[@doodelay]

Do mathematicians and physicists actually do all these tedious numerical computations or is there some computer that does it for them? I cannot imagine the hell it'd be to use Gaussian elimination manually

[@purpose_is_empty]

You use a program like for example MatLab.

[@jemima2611]

i love this guy

[@Mrpurrify]

Make more videos brother, you are going to be very succesfull!

[@ericsmtbadventures9]

Thanks for the videos, lots of help!

[@alhaithamaljabri2203]

Thank you Sir

[@Galenus0]

Great video! :)
