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.
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.
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. 😔
The video is great but you're wayyyyy too quiet! I had the volume turned all the way up on my computer and still could hardly hear what you were saying!

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
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
🎉
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
@Ultimatedoug222 well said.. you learned something from TH-cam
2x speed too icic lol
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
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.
ive watched your other videos and still couldnt get systems of equations. now i have this and im geeking this makes so much sense
Thank you for always being there for us as student's
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...
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
thx alot for this vid i understood cramers rule and i hav math exam 2morrow this vid was so helpful once again thx alottttttt
This is so well explained!! I really appreciate the videos ")
Description: Precalc
Me in linear algebra in college: THANK YOU
me in Calc IV still having to look at this again because i forgot 💀💀💀
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 are even far better than my university lectures
This guy is saving my year bro school starts in less than 2 weeks and i remember half of the stuff I learned
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
I really appreciate this lecture, very very good tutor!
Thanks so much this tutorial help me slot to understand I was so confused but now just understand after watching this
I hope I knew this guy earlier, his better than my lectures
Thanks a million! You are better than my text explaination
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
Thank you so much, your math solution help me for my upcoming exam......
thank you for saving my family from my burning house lsat night 🙏 thank you sire.
no rponlem
I love this guy❤
He is the best
He jxt made my life simple 😁
Thanks a lot you make every think easy
This page is incredible ❤😊😊
Tysm! This really helps, as I’m hopping into Algebra 2 at the beginning of 2nd semester :)
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 videos are always helpful 🙏
Real knowledge is ageless
Really nice and easy to understand. Thank you
Terrific job..Just to clarify like you said it's (a1 * b2) - (b1 - a2)
@방탄소년단 army you're right..thanks for the correction
You are doing a great job sir
You always save my day😊
This was very helpful, thanks
But why? Why would you ever do this???? The system can be solved in 1/4 of the time by the conventional route.
I'm not going to school Again 🤣 I'm buying wifi with my school fees for this guy's lessons
Thankyou so much❤️❤️❤️❤️🙌🙌😇😇god bless you🙌🙌
Your the best teacher
You made this so easy ,thank you so much
thanks man you da GOAT fr
Nice explanation. Thank you
Wow, much clearer to me now.
thank you so much you are a life saver
God bless you for helping out 🙏
I think my book needs to take Ur advice
Thank you so much😭😭😭
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
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?
Your voice is awsome
Thank you very much sir great tutorial
Omg thx so much this was such a help
Thanks
I needed this
Thank you man... finally I will not get a line of 7 in my report card...
The videos are explanative well
You the best 🌷💚
Thnx alot, this helped alot💯💯💯
Nice explanation ✌️👍👍
Thanks
You have the most soothing voice
VOLUME!!!! Unusable
thank you thank you thank you
thank you!
1:09 . 2:21 . 2:34 . 4:06 .
2022 and I am here. 🗽
So valuable
way longer than other methods for no reason just because it sounds fancy

Thanks dude this was so helpful
Rewatching this again.
Thanks 🙏
How to check when there is a denominator to?
thank you!!!
Very helpful. Thanks men
Eigenvalues and Eigenvectors
Video Tutorial Please...........!!
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
In India more than teacher
We believe in TH-cam teacher's sad but true
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.

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. 😔
What happens when you get a decimal?
Thank uuuuuuuuuu❤
Excellent! thank you
useful 🤙🤙
Thanks man can u make a video of arithmetic progression
So I can't figure out why you subtract in the equation?
lol this happen to me each time you make video about my exam qestions and when i back i find it here...
The Organic Chemistry Tutor is just a God who knows your desires and needs.
Awesome.
W teaching
Please tell me Cramer rule to find four variable values in 4*4 matrix
You do the same thing
I have simpler solution
just multiple times both sides by 0
There you go for a zero mark in exam ,😁
this is some legit
Sorrrry😢 I do not understand this
Then you have a problem
thx man
Maybe being an engineer isn't THAT important to me
Hm It is
Thanks man
I feel like this is way too many steps 😂 why can’t I just solve it like I usually do?
Same. If u are given with 3 variables like x, y and z it will take too long using these steps
The video is great but you're wayyyyy too quiet! I had the volume turned all the way up on my computer and still could hardly hear what you were saying!
thank you
