This helped me prepare for my end of year exam and I aced it, thanks a lot man. Really, don't think that I could've gotten through my second semester exam without your videos. Which makes me wonder how you got to understand them all considering how complex they are!!!! Anyway thanks!!!!
I wonder what people do when they reach upper division courses, when there aren't as many resources available. Do they just get filtered out and switch majors?
MR. Organic Chemistry Tutor, thank you for an excellent video/lecture on Finding the Determinant of a 4x4 Matrix. This is a classic problem in old fashion Linear Algebra/Systems.
bruh im taking pre calc online and I literally came across this today, but it’s a 3x3 matrix and the HW is due today. I did not expect you to make a tutorial on how to do this. Freaking clutch man!!
thank you so much, your job is amazing ! I'm a french speaker but I understood clearly all the video! keep going to make our studies easier and more success to you
I don't comment generally but I read in Class 7. In my school, Cramer's rule should be in class 9 or something like that. Even I understood your lectures that is 2×2, 3×3 and now this 4×4 one. If you think I am lying, then I swear to God.Amazing! Teach like this!!!
My professor speaks perfect english but I understood nothing when he showed this in the lecture. 40 seconds in with your video and I already get it. Thank you soooooo much.
Matrix is easy to work with but one of the most difficult to memorize after the class is over due to tons of components and terminology. One saving grace for me is “array” 😂
@@abdullahsehgal1614 hey you have a point but proper notation is very important. A matrix and determinant are not the same thing, so it would be incorrect to use square brackets when computing a determinant
I just want to thank u bro you are a true hero wherever you are I just want to tell u that u made a person happy 2day bcz of ur way of making things easier
Recommend a bit of gaussian elimination - if you add third row to first and third row multiplied by 2 to second and fourth, you will get a nice (0, 0, -1, 0) column and you only have to calculate a determinant of one 3x3 matrix.
Yeah, it does, adding a multiple of a row doesn't change anything. The other row operations do, but it is still just a scaling by constant you can keep track of.
My class had a lot of problems with this so my teacher said, "I guess it will be in the exams". We all laughed it off, but oh boy, we should have listened
I can't believe I did it.your Awesome 👍. Where were you last semester! I'm taking the class again however it all good . I have a better understanding now. Thank you so much
The instant relief you get when you search for something math related and immediately recognize the black board with yellow and white writings that belong to the organic chemistry tutor.
or you can simply transform it into an upper triangular matrix by performing row-elementary operation and then by multiplying its diagonal elements we get the determinant.
Explanation on the signs for each operation. Everything should be an addition and the sign comes from multiplying (-1)^(row-index + column-index). So, if you were to use the second row you should have: 2 x ((-1)^(2+1)) x |minor at M2,1| + 5 x ((-1)^(2+2)) x |minor at M2,2| + ... 2 x (-1) x |minor at M2,1| + 5 x (1) x |minor at M2,2| + ... -2 x |minor at M2,1| + 5 x |minor at M2,2| + ... This part gives you the sign for row 2 column 1: ((-1)^(2+1)) = -1. The easiest way to think about it, is to add the indices if its odd is - if its even is +. Row 2 Column 1 => 2 + 1 = 3 => odd - Row 2 Column 2 => 2 + 2 = 4 => even + Row 2 Column 3 => 2 + 3 = 5 => odd - Row 2 Column 4 => 2 + 4 = 6 => even + ...

When someone dislike his videos
Man is genius and deserves every bit
What's with the thumbs down people? He is the best tutor ever, seriously.
Face reveal please, it is important to know the person who has taught me from junior school to high school to university
He's never going to do that knowing how judgmental and creepy the internet can be. Some people even stalk and find people.

So glad you exist! Love learning from you
Thanks a lot I have an end semester exam tomorrow and your video has remind me what I forgot. 🙏🏽
It may be good practice to draw straight lines for determinant instead of square brackets. 5*[A] means different thing to 5*|A|

That is correct :)

Nice video as usual, please keep uploading more videos, you are helping us a lot. Thank you.
This is a GREAT way to find determinants
One recommendation......you can use Sarrus rule for determinants and solve it quickly within 2 minutes
Will you elaborate..... Put a video make your own channel that would be nice! #from India🇮🇳
Solving by this method is heaven.tq man🙌
THANK YOU. Exam in less than 2 hours. Lets goo
At last I'm cleared of confusion💓📖

that's gaussian which is essentially better than cramer's but he's using cramer's rule
@@physician8683 hes not using cramer, or else he would replace the values with the result to get the values
with what do you multiply the diagonal ?
@@physician8683 No he is not, that isn't crammer's rule
At 10:18 you said 318 was the determinant for a 3x3 matrix. It is 4x4 if I am not mistaken. VERY helpful, BTW! Thanks!!!

Thank you so much for the video JG , it was really helpful , Thank you.
This was really helpful
Love from India. I have fully understood after going through your video. I used to become very uncomfortable when I saw 4×4 order determinants.
Explanation on the signs for each operation.
Everything should be an addition and the sign comes from multiplying (-1)^(row-index + column-index). So, if you were to use the second row you should have:
2 x ((-1)^(2+1)) x |minor at M2,1| + 5 x ((-1)^(2+2)) x |minor at M2,2| + ...
2 x (-1) x |minor at M2,1| + 5 x (1) x |minor at M2,2| + ...
-2 x |minor at M2,1| + 5 x |minor at M2,2| + ...
This part gives you the sign for row 2 column 1: ((-1)^(2+1)) = -1.
The easiest way to think about it, is to add the indices if its odd is - if its even is +.
Row 2 Column 1 => 2 + 1 = 3 => odd -
Row 2 Column 2 => 2 + 2 = 4 => even +
Row 2 Column 3 => 2 + 3 = 5 => odd -
Row 2 Column 4 => 2 + 4 = 6 => even +
...
Thank you man this is really helpful
