“This is a very long process...” - It is indeed very lonnggg.. I’m getting DZ... 😅😂😭 Anyway, thank you so much for everything! Not just for math tutorials, but also chemistry tutorials. 👌
tip. you don't have to find value of z . when you have x & y just place the values in the equation and find z in the 1 variable equation . its not that much but 2 min is 2 min
I also think he made a mistake. Glad to see I wasn't the only one noticing. Thought it was a change in the way the math worked and my lack of knowledge, but the next example did the determinant the normal way.
Quick question, hope someone can help. He states that to find Dx the equation is Dx=c2b1-b2c1... but when solving for Dx he does Dx=c1b2-b1c2. This obviously equates to two totally different answers (changes the answer from 38 to -38). Which is the proper way of solving as one is said and written, but another is used?
Taking college algebra one and reading ahead to matrices. Test is on logs and systems. I wonder if cramers rule is either neater on paper or will help me with accuracy or if it's a shorter time to solve. Anyway cheers and thanks for the clear and thorough explanation! Maybe I can impress the professor with this method on the test...
🙌🙌👌👌👌❤✨You the best every time I getting stuck on something I look for your video and I feel so sad if I don't find it, I love you so much you're a life saver
super helpful i missed 3 days of class and when i came back i was so lost and now i have a quiz on this tomorrow , and now im confident i'll do well tomorrow.
Yeah, that had me really confused until you started doing examples and doing Dx the right way. There is nothing worse than a great tutorial video with some little mistakes.
Please specify when a mistake is realised apart from that it seems to be a good video, that Dx equation mistake left me a bit stumped for a bit thinking its my stupidity. going to continue watching from the video now.
there is an error 2:09 Dx is not =c2b1-b2c1 it is =c1b2-c2b1 just a small mistake if you know how to take determinant out of 2x2 matrix just knowing that matrix is Dx c1 b1 c2 b2 would be enough for you to solve it when he solves it with actuall numbers theres no errors there
why the determinant of 3 by 3 matrix is calculated in that way ? what is the intuition behind that.... I under stand 2x2 matrix determinant is obtained by elimination of variable...... But I do not understand the concept of elimination in 3x3 matrix...........

this guy needs an award for the thousands of students he has helped pass algebra
And calculus
Hands Down the Best Tutor for chemistry and calculus, passed my classes thanks to you!
Determinants is not a part of calculus
@@sandeep7973 maybe he just talkin in general
@@sandeep7973 You use them for differential equations.

Best Math channel ever! I'm doing a self-directed study and your teaching has been invaluable. Thank you so much, Keep up the great work.
I couldn't understand in my linear algebra class, but you explained so well. Finally, I understand now! Thank you so much
Me too but I'm OK now
Mistake at 1:58. Should be c1b2-c2b1.
thanks mate!
fking love u
thank goodness.
Mr. Siri we
Noticed that and was like wtf haha
I really enjoy your lectures, thanks so much. I recommend it to anyone out there facing any difficulty in matrix.. Soo easy-going.
Thank you so much! I watched this muted while listening to my music and still understood what was going on. Life saver! Appreciating you in 2021!
The best teacher and mentor in the universe, please post tutorials concerning time series please, that unit is one of a hell
By far the best tutor I have come across.

You are simply the best.
I am doing great because of your tutorials. God bless you
mate, you made it straight forward amazing.
Thank you so much for this great lesson Sir. Atleast I can do my assignment with no fear of failure
Hands down, I've learned more from this dude than some of my professors.
mate,you made this so easy to understand ,much appreciated
Hi, this is the best understanding I've had so far. Thank you so much but I'm confused at 1:58 and also at 5:00.
I think he made a mistake!

Jump out of the bulding!
@@tis_i_sana Guess you are a mistake
Even hero’s aren’t perfect 😔
Thank you, got a college mid term today on this
found this and your way of explaining is soooooooo helpful!! thank you so much professor 🤗🤗🤗
Genuinely life-saving.
Excellent video tutorial... Great for anyone needing to revisit the application of Cramer's Rule.
the formula for dx you said is: c2xb1 - c1xb2 and in the example you use the inverse
This Guy knows everything 🤧🔥🔥🔥
You're helping me revise through a great deal 🤝. Thank you. You are the best tutor 🎉

you saved me i got 93 out of 100 you are the best god bless you
Thank @Organic Chemistry Tutor ! This tutorial has been explained well and I understand it now.
Wow!
You really make it look simple.
You are the best. Thanks alot.
You know what? without you we are nothing, you are sent by god. God bless you.
Thanks for all the math videos, they are very helpful!
Very simple and easy to understand.. didn't get this in class
Super sir keep going best teacher in the world I ever seen ❤️❤️❤️❤️❤️❤️
I will pass my classes because of you
Awesome video, Thank you so much!!
Best tutor ever seen
your tutorials are amazing. hope i will pass my exam
same as me ......the best teacher
Superb explaination✌👌🏻👌🏻👌🏻🙌🙏
Thank you very much. You explained to well. I really enjoy your videos.
Absolute beauty
u r my absolute favourite....
🙌🙌👌👌👌❤✨You the best every time I getting stuck on something I look for your video and I feel so sad if I don't find it, I love you so much you're a life saver
Super chepthunnaru sir thanks
1:36 should be c1*b2-c2*b1
This just clarify everything I need to know 🥰
Thank you. I found this lec tutorial very helpful. 😊
Thank you. Excellently done
I like your lessons with equation and then examples, great, keep it up.
.. Super Helpful, Thanks a million
Thank you Sir!
Thank you so much🤍
15 /10/2024 passed my test with A+ because of this Guy thnx
Thank you so much sir
The process is great but i would rather use basket weave for D, Dx,Dy and Dz
Thanks for the video! It helped a lot and I really appreciate it.
Thank you so much.
Thank you
Thank you for everything!!
super helpful i missed 3 days of class and when i came back i was so lost and now i have a quiz on this tomorrow , and now im confident i'll do well tomorrow.
this very helpful we appreciate
Hi. at the beginning you said for D of x - c2b1-b2c1 => then you changed the formula to usual 2x2 as c1b2-b1c2. Just fyi
thank you sooooooo much
uyigqwele broh✊✊
I had to learn this in my electrical circuits class at university.
University? What age?
What grade are you on?
God bless you sir
Thanks for the great work
He made a small error at the beginning of the video while he was showing us how to calculate Dx but everything else seems fine thanks 🙏
The day that John Wayne’s horsed laid his head to rest, You became my Hero! Thank you Sir!
*horse
The "now what about..?" organic chemistry tutor
Thank you so much, you really helps!!!
you're the best
THANK YOU!!!
You have a mistake in 1:58. Please recheck.
Yeah, that had me really confused until you started doing examples and doing Dx the right way. There is nothing worse than a great tutorial video with some little mistakes.
do you really think he will?
Very useful ♥️
You are the best
super excellent work done
Please specify when a mistake is realised apart from that it seems to be a good video, that Dx equation mistake left me a bit stumped for a bit thinking its my stupidity. going to continue watching from the video now.
why is it c2b1 - b2c1 at 2:08? I thought it should've been b2c1 - c2b1? The example at 5:15 doesn't do this
thank you broo
Thank you.👌
If the determinant D is zero, does it mean to say there is no solution for the given equations?
Omg thanks you very much , holy so ez to understand
there is an error 2:09 Dx is not =c2b1-b2c1 it is =c1b2-c2b1 just a small mistake if you know how to take determinant out of 2x2 matrix just knowing that matrix is
Dx
c1 b1
c2 b2
would be enough for you to solve it
when he solves it with actuall numbers theres no errors there
I love this channel btw
if Cramer works fine for 3x3 matric then why to use gaussian elimination which is a bit lengthy ?
Can you find the determiner of a matrix whose rows and columns are different
On 2:07 you display that Dx is c2*b1- b2*c1 whilst it is the opposite. Dx= c1*b2-c2*b1
33:40 ..............like were you watching me?????? cause i have all my problem gone cause of just one sign change ........'sigh'
Thank god for you
Amazing Tutor
Thanks ❤
The best
At 17:00 can someone explain why the middle one is negative?
there is a mistake on the formula to calculate Dx (where you said : C2B1-C1B2)
Thanks sir
is the middle one at 17:00 always negative?
I am not saying that I'm cramming for my college algebra but yeah I am..
why the determinant of 3 by 3 matrix is calculated in that way ? what is the intuition behind that.... I under stand 2x2 matrix determinant is obtained by elimination of variable...... But I do not understand the concept of elimination in 3x3 matrix...........
Great..
