Hey can someone explain how to find the individual parts of the jacobian? I’m using this vid as a study guide for a test and I’m struggling to find the multiplicative factor
This guy is doing exactly what I used to do and get wrong all the time! I eventually learned that you don’t define u= f( x, y ), v= g(x, y ) but you imagine the BACKWARD transformation, x = F( u, v ), y = G( u, v ).
Excellent vid my friend. I took multivariable calc years ago and never really understood the jacobian or its purpose. Your explanation made it so simple and obvious. Thank u
Just watched the multivariable calculus playlist in one go as I have my viva exam coming up. I had learnt it all before but forgot most of the things due to few months of gap. I'm so glad that this playlist exists. Thank you so so so much!! This worked as a great revision material for me.
I am actually shook. Whenever I watch videos like these, I expect to be disappointed. But when you started discussing the cross product, everything suddenly clicked.
Thank you Professor Bazett for an excellent video on the Jacobian. I am taking Multivariable Calculus (II) right now on edX offered by MIT but I always return to your videos because of your clear and lively teaching style. I look forward to many more. You make the videos entertaining as well!
I was about to google to find out the reason why we needed the Jacobian, your video presented is so beautifully it can't be beaten!!. Thank you so much !!
I’m a visual learner too… but being a stupid visual learner i had to watch this twice, because the first time i was watching it in small screen mode… small screen mode confused me because the dark red font used for J was no J enough, so i thought it was a close bracket… and this distracted me to no end looking for an open bracket in small screen mode. Jeeeez… I was so relieved after switching to a larger screen to make up for the idiosyncratic font style for depicting J… But i am definitely reaching my end goal of getting better intuition on cross product, curl, determinants and Jacobian! Thank You!
I was banging my head trying to understand the jacobian cuz it was introduced with the chain rule topic in my school. This video just made it very easy to undertand now. Thank you very much
Thanks sir after exploring whole day in youtube to understand the jacobian your single lecture gave me a tremendous touch of the concept of jacobian Really sir you are genius and also have very good experience as compared to other professionals 🥰🥰🥰🥰
This channel is awesome 👌 You bridged the gap of the required imagination to understand the concepts by the brilliant use of animation. Explaining something that can be seen brings the beauty of Math. I am following all your playlist just to learn and see again this beauty which I missed before . Thank you 😊 Moving on to Calculus IV 👋
The motivation for the Jacobian explained with the u-substitution method from calculus 2 was very helpful for my intuition behind this topic. Thank you.
at no point in my maths undergrad did any of notes/proffs explain the (actually simple) motivation for transforming with the Jacobian as well as this video - it was v enlightening... Thanks a lot!
Your explanations have helped me a lot, I am very grateful! Thank you very much for creating context at the beginning of each of your videos and for making such clear points!
Awesome video! Thank you! Interesting how the Jacobian features into integration when I first learned it for using newton's method for vector functions and vector root-finding, needing to get the partial derivatives of the vector function F.
That part at the end was mindblowing. That literally tied everything together and I can't believe they never showed that between my professor's lectures and two textbooks!
9:10 that explaination was excellent. It seems stupidly obvious now why we scale with the jacobian that I'm kind of dissapointed I didn't try to heuristically derive it myself. Damn.
Hi there! Thank you so much for this video!! I was wondering if there is an explanation on how to invert the Jacobian matrix if solving for y and x becomes messy.
It takes time to finally figure out why Jacobian determinant works in variable change of double integral. I traced back the dependency and find a resource that is as great as this one, the jacobian matrix section from Khan academy.
At 9:10, the cross product is the same as the determinant of the two vectors as far as I understand. Then how the heck is du and dv OUTSIDE of the determinant, arent they a part of the vectors that should go in to the determinant? Thanks
Brilliant explanation sir ! I got stuck on the subject trying to understand 3blue1brown's ideas..anyway these last minutes from this video made me to understand Grant's
Could you find the scaling factor in 1d U sub, instead of treating du/dx as a fraction and solving, by using the Jacobian in some single variable way and get the same scaling value?
Thank you very much, this helps a lot. I still have a question why the Jacobian is defined in the matrix of these orders, not define as it’s transpose?
Hi Dr.Trefor I really love the way you teach math. But I have a question. Should we take the absolute value of the Jacobian in the substitution? Thanks in advance
Thank you so much Trefor, your series of videos really helped me clarify some questions I had from Calculus Adam's textbook.. Keep up the great work and thanks for teaching! :)
Quarantine isn't that bad when we have people like you helping us out, thanks sooooooo much 🌸🌸🌸

Can’t believe quarantine was four years ago now…
@@boctama6626 true :(
Greatly appreciated the second half as to WHY the Jacobian comes into play!
The Jacobian part in the end is pure gold

help please someone
@@treynoe4934 what do you exactly mean by the individual parts, elaborate a bit ill try to help
do u mean the functions inside the determinant?

This channel doesn't make me feel that I'm quarantined at home.:)
This is the absolute best explanation on the topic I've watched so far!
Great to hear!
Thanks a lot Dr. Bazett! I searched many materials and so far to me you are the only one that made the vectors transform part clear. Subscribed.
That was the last one of the whole series on Calculus 3. I watched every one and they were brilliant. Thanks for all the insights.
This was absolutely top class as far as an explanation on an advanced topic can be. Great
This is the best tutorial on change of variables I've watched!
Jacobians tie together powerful ideas from linear algebra and calculus.
You are so good at explaining the intuition of things. You are a great teacher, thank you.
This is one of the most beautiful explanations on the intuition behind Jacobian I have come across on youtube. Thank you.

Man, I was struggling to understanding the reasoning behind the Jacobian, but your video provided me the insight thanks a lot!
Never found mathematics this much interesting.. Thank you for all the efforts you have made for us sir.# respect
AS SOON AS I SAW PARALLELOGRAM AND HEARD CROSS PRODUCT IT ALL CLICKED; THANKS MAN

simply amazing...! this is such a wonderful explanation..!! I am really sick of the way they have been teaching this stuff at university..!!
I love your attitude! You make Calculus so much more enjoyable to learn :)
That explanation about the origin of the Jacobian factor is very helpful!!! Thank you!!!!!
Thank you so much for this video. I wish my Calculus 2 classes were this straightforward.
What an absolute legend, thank you so much for this.
I never think that i understand this concept in such an easy manner 🙏🙏🙏
Thanks !
you truly deserve more subscribers !
I always feel you are underrated.

isn't that part cool!?
this literally saved me from failing in my exams
A really informative explanation and presentation!
i finally understand why i kept hearing about this dawg so much
finally this topic got crystal clear.....thanks a lot 😊😊
Wow, I can't believe, you made this look so easy now ✨🌺, you are best 🙏
Thank you finally a rigorous explanation
Glad it was helpful!
Ohh , i was looking for the video ans now i have found it
Nice explanation sir for the basic
this is such a good intuitive explanation, my textbook just derived it without any intuition lol
Feels like Obi-Wan Kenobi's Brother is teaching me math QAQ.
SOOOOOOO helpful. Thank you for taking the time to make this!
dudee explained so well sire!!! thanksss a ton
That was amazing, visualisation hits different from a table at university. Thanks!
Thank youuuuu! Got my 3rd year finals coming up and this really helped me get my head around it. :)
Good luck!

Love it, it makes a clear picture to me
it's just too great and your voice is amazing
Completed the multivariable calculus for the first time with intuition and visualisations. Thanks Professor. Looking forward for Ode series.
Congrats on making it to the end!

Hi there! Thank you so much for this video!! I was wondering if there is an explanation on how to invert the Jacobian matrix if solving for y and x becomes messy.
sir ur videos are magical !!😌
very very helpful and I love the way you explain!!
Very nice explanation!
best explanation + nice visualization
Finally i understand this J. Great video sir😊
Jacobian also takes you from moving frame from rest frame via Lorentz Jacobian in Minkowski space which is just a hyperbolic rotation
Excellently explained
Jacobian? More like "Just awesome; you're the man!" 👍
I wish I could like this video more than once
Thanks you Dr Trefor! Absolutely amazing explaination :))
