MR. Organic Chemistry Tutor, thank you for another smooth explanation of Cramer's Rule - 2X2 Linear System/ Equations. This is a well-known rule in Linear Algebra.
you just saved my life, I have a math test tmrw and I knew nothing. I come to your videos and I learn the content in an hour. You explain the content so perfectly and efficiently. You deserve a medal.
quick question: when solving for the determinants (D,Dx,Dy,) once you multiply how do you know which sign to use or is it just subtract 8x + 4y = somethin 2x - 5y = somethin D = --- --- | 8 4 | | 2 5 | = 40 (how do you know whether to subtract or add?) 8 --- ---
What is the reason behind the specific arrangement of the variables into creamers rule? Is there any derivation or proof video that shows how the rule works intuitively?
For a system of 2 equations, that may be true (substitution or elimination are probably faster). When you start doing systems of 3 or more equations (for 3 or more variables), Cramer's rule is probably going to be much faster. But, learning the 2x2 case is a helpful stepping stone for understanding what you are doing in those more complicated cases.
yes. but there are teachers in youtube in India who do exactly the same thing as our normal teacher does. they seem to be teaching 'great' but at the end you realize you learned nothing. but they do a lot of other things to create a false excitement.(which is called publicity stunt) some coaching companies do such for their promotion. they either think we know everything previously or they make us fools. and often they talk about things completely useless and totally unrelated to education. both offline and online, youtube teachers do the same. but teachers on youtube who are very underrated teach well. they teach everything deeply and step by step like this man. actually there is a way of teaching. anyone who knows cannot be a good teacher no matter how much student they collect by grabbing attention. In India tution is a buissness to almost every teacher except some. primary reason of teaching is not to help the students. I have a lot of experience. I went to various pandit teachers to learn maths. they are very popular. but as soon as I entered their coaching I realized I was not learning a single thing. finally after class 9 with literally zero knowledge and too bad marks I went to a teacher near my home. he taught me in the way that I got 99 out of 100 in class 10 and now having maths as a elective subject. sadly, he has health issues now so he can't teach anymore. 😔

Hello Friend
any video about vector space ?
exactly what I needed. you explained it in 5 minutes what took my prof 50 minutes and I still didn't get it. thanks bro
Once again... you just explained to me in 5 minutes what ive spent weeks trying to learn. Thank you!
My teachers explained this for 5 days that is equal to about 3 hrs and here i learned everything i needed in just 5min😳✌️ just wow💙🥀 thank you
I guess it's 10 Min and 32 sec
@@dodo_can_swim for 2 examples, 1 example would be 5 minutes and 16 seconds, which proves the point of the original commentor
@@ultimatedoug2227 well said.. you learned something from TH-cam
2x speed too icic lol
Cramers rule was extra credit on my test and I literally watched this vid while doing it and aced that shi 💀thx bro
Yes , you are true
🎉
You're a life savior, I've been struggling with some assignments for a week now and I finally understand how to solve them.
So grateful av struggled alot but now av understood
Thanks alot uv helped me it have tsken time to understand in class but here even not 3min am ok
I missed all last week cause I was sick and that whole was cramers rule so this really came in clutch
ive watched your other videos and still couldnt get systems of equations. now i have this and im geeking this makes so much sense
Bro you’re a genius. I thought I was stupid because I didn’t understand in school
I am Indian and I study class 10 or I have read this
Anyone ask?
@@lolerishypenope, but you bothered to comment so...
MR. Organic Chemistry Tutor, thank you for another smooth explanation of Cramer's Rule - 2X2 Linear System/ Equations. This is a well-known rule in Linear Algebra.
Thank you for always being there for us as student's
so much easier than my lecturer. thank god you were here to help. she only gave me a 3 by 3 and that was horiable. thanks again
you just saved my life, I have a math test tmrw and I knew nothing. I come to your videos and I learn the content in an hour. You explain the content so perfectly and efficiently. You deserve a medal.
This is so well explained!! I really appreciate the videos ")
This guy is saving my year bro school starts in less than 2 weeks and i remember half of the stuff I learned
thx alot for this vid i understood cramers rule and i hav math exam 2morrow this vid was so helpful once again thx alottttttt
Description: Precalc
Me in linear algebra in college: THANK YOU
me in Calc IV still having to look at this again because i forgot 💀💀💀
you are even far better than my university lectures
My teacher attached it on our gclass and it's really helpful. She really has a taste.😄
I was so afraid of mathematics until I found your channel. Now, I am not afraid anymore.
a fresh of breath air compared to the usual substitution or elimination that the teachers want you to do.
I don't have a maths lecture but u just filled the gap be blessed
Thanks so much this tutorial help me slot to understand I was so confused but now just understand after watching this
Thanks a million! You are better than my text explaination
Thanks a lot you make every think easy
I really appreciate this lecture, very very good tutor!
thank you for saving my family from my burning house lsat night 🙏 thank you sire.
no rponlem
Thank you so much, your math solution help me for my upcoming exam......
Really nice and easy to understand. Thank you
Tysm! This really helps, as I’m hopping into Algebra 2 at the beginning of 2nd semester :)
This was very helpful, thanks
Your videos are always helpful 🙏
You are doing a great job sir
This page is incredible ❤😊😊
You made this so easy ,thank you so much
Real knowledge is ageless
My teacher explained in a pretty easy way and after months I wanted to revise but you just made this all harder.Atleast you tried tho.Thanks for that
Your the best teacher
Nice explanation. Thank you
You always save my day😊
Wow, much clearer to me now.
I love this guy❤
He is the best
He jxt made my life simple 😁
Terrific job..Just to clarify like you said it's (a1 * b2) - (b1 - a2)
@방탄소년단 army you're right..thanks for the correction
quick question: when solving for the determinants (D,Dx,Dy,) once you multiply how do you know which sign to use or is it just subtract
8x + 4y = somethin
2x - 5y = somethin
D = --- ---
| 8 4 |
| 2 5 | = 40 (how do you know whether to subtract or add?) 8
--- ---
it is just subtraction
thanks man you da GOAT fr
Thanks
I needed this
Thank you very much sir great tutorial
thank you so much you are a life saver
God bless you for helping out 🙏
Thankyou so much❤️❤️❤️❤️🙌🙌😇😇god bless you🙌🙌
The videos are explanative well
I think my book needs to take Ur advice
Thank you so much😭😭😭
But why? Why would you ever do this???? The system can be solved in 1/4 of the time by the conventional route.
What is the reason behind the specific arrangement of the variables into creamers rule? Is there any derivation or proof video that shows how the rule works intuitively?
Omg thx so much this was such a help
VOLUME!!!! Unusable
my teacher ran out of time and forced us to learn this on our own. if this video didn't exist i probably would not be here today
THIS IS JUST GREAT, u helped me do my Modules as a grade 8 student, This man here is truly a lifesaver to us students ♥
hope you'll do more ♥♥
Your voice is awsome
thank you!
thanks very much
thank you thank you thank you
You the best 🌷💚
So valuable
Thanks 🙏
How to check when there is a denominator to?
thank you!!!
Thank you man... finally I will not get a line of 7 in my report card...
1:09 . 2:21 . 2:34 . 4:06 .
I'm not going to school Again 🤣 I'm buying wifi with my school fees for this guy's lessons
Thnx alot, this helped alot💯💯💯
Nice explanation ✌️👍👍
Thanks
thx man
Rewatching this again.
2022 and I am here. 🗽
Excellent! thank you
way longer than other methods for no reason just because it sounds fancy

Very helpful. Thanks men
Thanks dude this was so helpful
Thank uuuuuuuuuu❤
Thanks man can u make a video of arithmetic progression
Awesome.
What happens when you get a decimal?
useful 🤙🤙
Eigenvalues and Eigenvectors
Video Tutorial Please...........!!
You have the most soothing voice
thank you
W teaching
or you can just use substitution/elimination
yes you can,but it's not trivial if the degree of your linear system is big ( example n > 4 )
Damn double L
this is some legit
Thanks man
yay math
i love you
So I can't figure out why you subtract in the equation?
wow!
Jay Sri krishna
Super helpful
Sorrrry😢 I do not understand this
Then you have a problem
Please tell me Cramer rule to find four variable values in 4*4 matrix
You do the same thing
In India more than teacher
We believe in TH-cam teacher's sad but true
