- This precalculus video tutorial explains how to determine the inverse of a 2x2 matrix. It provides a simple formula to determine the multiplicative inverse of a matrix. You can check to see if you have the right answer by multiplying the matrix and its inverse to see if you get the multiplicative identity matrix I2. This video contains plenty of examples and practice problems.

You are amazing
Good
how can l use tranformation?
I love you
i got an A+ in physics at my first year because of this guy......i really appreciate your great knowledge idistribution
I got AA too thx you so much
I too, so grateful
Bro my school has sacs yeah, kinda like really important test, and my god they are twice as hard as the exams
can you give me that A+
@Cristian Douglas bot
Whoever is the face behind this channel, know that you are and will forever be a legend. Thanks 'coz you helped me a lot during JHS up to my college years right now. :)
This is what I call Free Education for all
You are currently getting me through Calc 2 and Linear Algebra. Thank you.
How can I find the videos of calc2 and linear algebra because I couldn’t find them in the playlist 😢?
the way i failed the fuck out of calc 2 i'm in lin alg rn!! 😭
Definetly one of the better tutors on the internet. Explains things very well and clearly.
Honestly, I am so extremely grateful that this channel exists, thank you so much for taking time out if your day to help people who are struggling with understanding math. You make it so easy to grasp the concepts. Thank you so much!
his guy is legendary-his voice and explanations make complex math feel as simple as A to Z!
THIS GUY IS FROM ANOTHER WORLD SENT TO HELP THOSE IN NEED, GOD BLESS YOU AND YOUR FAMILY, I AM LEARNING SOMETHING WHICH MY LECTURES DO NOT TEACH, THANKS A LOT
your videos are so useful!
Kindly increase your volume a little bit.

@@LearnwithAakashVerma woow... that. Was. Loud
Mr. Organic Chemistry Tutor, Thank you for a productive and helpful video/lecture on 2X2 matrices. I took Linear Algebra in the early 1990's and watching these videos are super helpful.
wha-
aight unc
I literally cant thank you enough for this video, I have been so confused because my class is strictly self taught and this has been more beneficial than my in person college algebra class.
Thank you so much man, I honestly learn more from you than all of my teachers. I seriously greatly appreciate you!!!
omg I have watched a TON of videos on this matrix inverse and this one is the best. Straight to the point and easy to understand. THANK YOU!!!!!!!!
i have linear algebra exam in about 2 weeks and your videos really help me get through this i didnt really know how to understand these topics but thanks to you i think that im gonna ace it
one of my dreams is to meet you man.
Friendship ended with Khan Academy now The Organic Chemistry Tutor is my friend
i had my final exam at university today, i study aerospace engineering. i got this kind of matrix question. it was a 2x2 marix and i done it easily, just came here to make sure ive secured the easy 10 marks
This channel is my favorite math YT channel
Thank you for always coming through we owe you a lot
He is literally a life saver im so gonna ace my math exam now !! thankss
How does he know everything
thank you so freaking much sir. may the Lord bless you
A millions thanks I finally got the second part
You are helping a lot.... I have a test tomorrow!!
Getting all these blessings, dude, you've got a first class ticket to Heaven
You saved my life, thank you.
❤❤ I don't know how to thank you, dear man. Thank you very much. I am an Arab from Egypt and I could not understand from the my teachers, but I understood from you.
Thanks for the video, I followed through so easily.
Greatest teacher 👨🏫 of all times
Organic Chemistry thank you so much for your kind of tutorial it is very productive God bless you more power 😇✨
THANK YOU!! I have a test in 2 hours lmaoooo wish me luck
I'm sure your test went well! :)
Same here
how did it go? (..also, same here)
@@J-wm4ss the results aren't out yet
ahhhh me too ( after 1 hour lmao ) so nervous
It is amazing how you simpfied this calculation
Best teacher ever understood very well
Thank you 🙏 you are better than our school teacher our school should hire you 😂😫
Perfect explanation .clean and clear .
these lessons are soooo helpful👏👏👏thank you a lot
These TH-cam tutorials are really helpful ..
U should sub to studypug , it's actually really helpful, it's as good as this in terms of teaching ( I prefer this though ) but study pug is way more detailed in terms of topics
Its quite cheap too if u get half price
R800 ( Well in dollars, maybe 36$ or smtn )
man,you're explaination is the best of the best🙌❤
thanksss I remember everything now
Your teaching is helping me a lot
If there is one thing I despise about math is the... lack of reason for each step.
It's just, hey here's some 'matrices and inverse and yada yada'
Yeah, just takes this and do that with it.
Why? What's the goal?
Well of course that'd involve knowing turbo calculus or something.
What continuously trips me up is just the random addition of new variables that seem to come out of nowhere. I ask myself, why do we do that? And there's no answer that doesn't involve learning 3 new languages and entire new alphabet of symbols.
Meaning it just boils down to 'just do this' which is fine until u just get blasted with new lexicon and terms ur unfamiliar with, which makes me want to define them but no there's no definition it's just- is? Like, what is even the goal?
We're finding the inverse? Fine, that's at least a goal of some sort. Why are we skippitylackin the matricial bamferang now???
Arrrgh, i frkn hate math.
Thanks sir. U r my maths hero. Thanks sir. My headache is out now.
So is your English
Fell asleep during my teacher’s lecture😓 this guy probably explained everything better than my teacher did! My homework thanks you
When you search the dictionary for the definition of being The GOAT, this guy comes up
i owe this man my life
@5:16 it should be -1 in the 2nd row righ5
多謝!
Thank you very much. You explain it in a very clear and simple way
Greatest teacher of all time.
one day i wish to see you bro to tell you thank you
Youre the best fr.your vids are very helpful 👏👏 ThanKs alot
When you got a test in a max 2 hours so watching at 1.75× AND STILL GETTING IT ALL!!!
Best teacher ever
I got an A in chemistry bcs of this guy and now I'm taking degree of chemical chemistry. Thank you for your help
Sir Thank you so much,your explaination is so clear to the point, It helps me alot.
Your videos are very useful Sir. I wish I could meet u one day.
Thank you so much !
Amazing channel for math
you really helped me a lot, thank you so much!
Bro you are so genius thank very much for lectures.
Its very helpful thank you for uploading this type of video
Your videos helped me a lot thank you so much 🙏🏻🙏🏻🙏🏻
I am very grateful for your help ❤
I will never understand why my professor taught me the pivot method when this simple of a solution is out there. The education system needs to reevaluate itself
Wow
God richly bless you for your dedication
you very good to the engineer sir
Thank you very much this was very helpful
Thank you ur videos always save me
thank You So Much my Math Book Do This Problem Much More Complex But Your Video Helped Me To Understand The Concept Quickly.
Thanks sir. Finally i did it.
u are being made for us, appreciated
I love u guys.
God bless you
You are fantastic man
Good Explanation👍👍
Thank you for making this super clear
You make me ignore my lecture bcz I know that u the one who will get me through in just few minutes 😂❤
You are a life saver
Tell me the differences between matrices and matrix?
Saida Rahman Mohona matrix is singular form of matrices
You blessed us ❤❤
please do the matrices for simutaneous
You make it simple bro
another great video! thanks a mil
You are a lifesaver
Me coming to here convincing my brain how to do this
U save my life
you always surprise me thanks
Thank you so much sir.
Thank you
Thank you very much
Wow i wish i new before..........there is some one like you at you tube 😔😔😔
is the total or result still the same??
because in our class we use it like this:
[a c]
[b d]
and yours is like this:
[a b]
[c d]
i mean is it the same result when making it in inverse matrix????
Its the same because you are still multiplying a with d and b with c
Bro thank you so much
Please may I know the software you've using for your videos
You are so good 😂😂😂😂
Thank you ssssm❤
It's incredible but what do we do if that number 1on 1 is greater 👏😓
I have a question what if 2 and 5 were negative numbers
Thank you
But it didn't end up with 1 over 1. what then?
Always helpful😁
