Absolutely the best explanation I've seen. I've been studying matrices for 6 months. Authors and profs and tutors are so focused on solutions and processes, they forget to explain what is actually happening; they forget what the math represents- the thing we really ought to know. Thanks!
This has totally blown my mind! Months of trying to figure out how matrices work, and it's all come together in this short video! So brilliantly explained and shown. Thank you so much!
For the people equally confused as me when seeing the last matrix problem for the FIRST time: (BxA)=(a,b,c,d).(a2,b2,c2,d2) = (a.a2+b.c2)= 0 ; a.b2+b.d2= 1 ; c.a2+d.c2= 1 ; c.b2+d.d2=0 => BxA = ( 0, 1, 1, 0)
Great video! I’m just very confused because I thought matrices were displayed as (x,y) but in the matrices here it’s represented vertically. Why is this?
At the origin this makes sense, but what about when you have objects deeper in one of the quadrants? How do you tell the difference between reflection in the y-axis and rotation 180 degrees? Because with that one square in that one location, the two are indistinguishable.

but i am nat getting it men and yet am left with some kind of assignment
I learnt more in this 3 minute video than an hour of further maths A level class. Thank you!
A level???!?! Seriously??? We learn this during 10 grade

literally watching this right before my igcse exam! you saved my life!
Same wish me luck
Dull I know its late, but how’d it go buddy?

Thanks Dude, I have an exam tomorrow & hope this will help me!
RIJAN RAI me too , wow 😲
@@iman7961 wow 😮
I’ve got a further maths exam tomorrow, my friend sent me this and I feel more confident with matrices
me too this video is a lifesaver
About tl write one of mg biggest maths exams rn.... this.. saves me... so much
You deserve a nice blowie for that awesome explanation. thanks
explained way better than 90% of the profs
i missed this lesson, so hopefully this’ll help me to understand
why didnt I find this earlier.. this was so helpful, thanks!
Thanks man,May God bless you

WTF is even happening at 2:36. Can someone please explain his order of multiplying and why?
thx for the explaination, it helped me a lot
Thanks, it cleared up how to solve my homework.
this saved me thanks!
thank you so much lovely human being!
Thanks and I needed your help more.

cheers mate i swear to god why dont my study books explain stuff like this
for A, can it also be a rotation about the (0,0) mark in a clockwise direction of 270 degrees
ye i had thought of that too
@@dantowik808 damn i dont even remember watching this video lmao, glad my comment helped.
@@tristanmungal1979you still have this account 2 years later?
Watching this video when it’s 10:10
great video! thanks! :D
you are a godsend
I've got my A level tomorrow will update u if this helped me pass
Have you done any videos about transforming unit squares using a matrix?
I have a question, is there a particular matrix that will allow you to reflect a vector across this plane (x+y+z=1)
This helps a lot thanks!!
Very helpful, thank you!
From where did he get those matrices???
thanks for this video!
pliz make app
thank you
What if we had a 3 point shape and a 2×2 matrix
If it is A followed by B why did you do B times A?
Lace Rav A followed by B means b is first ands follows behind it, meaning BxA
2:52 is he taking the det??? smh
Thanks !!
to the point 👍👍
Love you, thanks!

you made a mistake. the coordinates are not plotted according to the vectors.
please elaborate?
