You are an amazing person. Thank you for explaining what calculus actually means, and WHY things are done not just how, I watch these everytime I do homework. Please keep making these:)
I was so puzzled by fxy and fyx, my econ professor did not explain it well. Thanks so much for the video, I finally understand how to find these partial derivatives!!
Thank you for these videos. The only calculus 3 teacher next semester likes to tell too many stories and doesn't care as much for math. He's like a 40 yr old man who acts like a teenage douche bag. Anyways, I'm anticipating terrible lectures next semester so I am watching your vids and doing as much as I can before class even starts.
amazing....awesome examples, i learn soooooo much more from your videos than i do in lecture. Calc 3 is tough without good fully explained examples like these. Thank you so much
At 9:11 , your derivative with respect to y at the top right of the screen is wrong. You just made an error when you copied it down from the previous slide. It should be an x^2, not a y^2 (for the coefficient).
this makes so much sense now if you wrote u and du or v and dv on top of the values you were using the product rule on it would have been more clearer but other than that i loved this video and i can now do second order partial derivatives
hi I thought mixed partials are not generally the same. would you please explain this more? or could u please tell me in which cases they are not the same? Thanks
Mixed partial derivatives of the same pair of variables, have to be the same, per Clairaut's theorem. This is also evident when you take the curl of the gradient, and should also get zero, because the gradient of any scalar function is conservative. The curl of the gradient is nothing but mixed derivatives, and you'll have symmetric terms to that matrix.
@@brandonlipinski Another thing is, they could be foreshadowing the material for next year, as an example problem. To me, it clearly is an example of scope creep, where the instructor is expecting more than reality from the students. If you are given all the guidance, this is something you can do as a Calc 1 student. Just like there are problems on beam theory as an application in Jimmy Stewart's Calc book, despite it being very likely that most students wouldn't know anything about beam theory than what is given in the problem.
Thank you so much, this was the only vid that actually explained the mixed partial.
Exactly!!

I was completely lost in the second order of partial derivatives, you made this explanation super concise and easy to follow!
ong
You helped me understand my Calculus class better, I appreciate your effort and teaching skills! Thank you!

First minute explained everything that I needed THANKS!!!!

I finally am able to understand how to solve cross partial. Thanks!
explained the mixed partials much easier than my book so thanks
Well explained. This is going into my Cal playlist!
What else is on your Calc Playlist?
Asking for a friend...............
thanks alot!!!!! Reading through lectures and notes and I just couldn't understand.. 3 hrs to final exam!
thanks a lot bro missed 2 minutes of class and was confused about f-xy and f-yz
excellent work I must say,excellent work!
this makes so much sense now if you wrote u and du or v and dv on top of the values you were using the product rule on it would have been more clearer but other than that i loved this video and i can now do second order partial derivatives
yes, there is a mistake, agree
How do you know when to use the product/quotient rules? Thanks!
You covered so much in one video. Thx
Thanks sir, very helpful and concept clearing
Which software do you use for graph ..plz tell me
Perfect explanation
Thank you
good , but seems liked you do the product rule different than shown in the book. which makes it a bit confusing.
can you do an example where you compute d^2u/ds^2 given that x = e^t tan(s) and y = e^t tan(s)
this video saved me THANK YOU
This was really helpful .Thnk you
What about when a table of values is listed, how do you find the second partial derivative of xy?
Thank you so much, this was so helpful
This helped sooo much!!! thank you! I shared with my friends!
what if the function involves three variables? Eg. f(x,y,z) how do we do second partial derivatives for this type of functions?
Omg, thank you, thank you this is gold
This is great stuff, thank you!
Great presentation, thank you.
3.30 - Where the magic happens! Thanks alot!
Thank you for the explanation!

жәй тілмен жақсы түсіндіреді екен
super, very well explained! many thanks!!
I'm in calculus 1... why the hell is this shit on my final😂
That's a good question, because this is clearly a Calculus 3 concept.
@@carultch that's what the guy at the tutoring center said as well... i go to osu and our class average on the exam was a 45%

That is good to know. Thanks for the comment.
thank you i love you
Thanx alot bro you jus gave me a pass
THANK YOU !
5:00 for those looking mixed partials
Oh god , thanks man.
thankyou chacha
I am crazy about maths.....
i wanted to know the calcula deeply now i am shifting my interest to the or towards the DISCRETE MATHSSSSSSSS.HELP ME IF YOU CAN...
Thankyou so much😊
bro youre awesome
thankyou so much
thank you brother
Awesome! Thank you
THANK YOUUU! 🤍
You’re welcome 😊
Thankyou very much!
Great! 😊
