❖ General Chain Rule And Partial Derivatives ❖

I was 13 years old taking algebra 1 when this video was published. Now I'm 20 years old, taking multivariable calculus, and i couldn't be happier that i found this channel. You're awesome, Patrick!

MY GOD I UNDERSTAND THIS.
When I graduate, I'll pretty much owe my degree to Patrick here.

I enjoy getting high and then watching all of your videos. Your voice over is perfect for the stoned context. Pretty high right now

I have spent hours in the traditional college classroom and learned very little. I sit around my computer and watch your videos for 10-15 minutes and I able to understand and solve the problems within minutes. Your videos are excellent, thanks a lot.

I was eight years old when this video was published , and you know what ? This guy teaches mathematics better than my university's professors who gets thousands of pounds every month ! He doesn't have the number of certificates they have but he is better than them ! Thanks Patrick ❤️

WOW! You explain in 10 mins what my lecturers can't explain in an understandable way in 10 hours. Not only do I pass exams thanks to your vids, I actually learn something too! You absolutely ROCK man! Will donate! :)

Man thanks patrick. you saved my grade since 7th grade. now im in college, and im still watching your videos. thanks very much.

this guy saving my stupid ass since 2014

thank you Patrick, i owe you so much and a lot of late nights cramming before an exam are spent watching your videos. stay safe, you are a blessing in the youtube world.

Patrick I was watching your videos when I was in elementary school now am doing engineering and your videos are still quite handy to me, may God bless your soul wherever you're now 😊

PatrickJMT: the math savior of the internet.

Hello, I just want to tell you how thankful I was to come across your channel! I have never been very good at math. When I started Calculus this semester, I came across your channel because I didn't understand anything in the class. You made everything seem so easy to me! I was one of the only two people who made an A on the first test with the class average being a 32. It was definitely a self confidence booster when it comes to math because this has NEVER happened. Thank you so much.

After 12 yrs your video is among the best

thanks! telling others about the videos is the best donation you could make! :)

My textbook is full of jibberish and it takes me 30mins to an hour to finally understand what the heck is going on, but your videos in just approximately 10mins you cover what an hour lecture and of textbook reading would cover..thank you so much..You can be sure once I get my degree and a well paying job I will gladly donate my fair share :)
P.S I'm currently studying Computer Science

OMG, thank you Patrick. My professor spent 1hr and 30 min trying to explain this and "FAILED" and it only took me 9 min on RUclips to understand it. GO University of Patrick!!!!

Love the tree technique! Makes it so much easier!

At my university we are doing this in Calculus 4.
Patrick, thank you very much for doing these videos. They help more than you probably think.

PatrickJMT is the only dude i support on Patreon and its still paying off! way to go man!

i was gonna say "I wish you were my prof" an then i realized you already are. you replaced him a long time ago. I'm pretty sure my entire year learns from you more than our actual prof. Thanks so much Patrick, you really are my Hero

Patrick I love u keep making math videos and saving my GPA

I can't thank you enough Patrick, each lecture you give is incredibly helpful and simplified. you awesome man! the only problem is that you are left handed and you obstruct me quite a lot when trying to take notes. LOL. I AM KIDDING.

Dude you're actually the best. A textbook can give you the formula, but you always need to learn it at least three different ways to master it conceptually. Your videos are one of my frequent stops.

finally someone that can explain this without being vague or stuck up!

I am in love with your teaching methods , even our so called qualified teachers are not able to teach us like your simple tutorials. May God bless you.peace.

From one Patrick to another, you're a lot smarter than me.
Also you're v's look a little like square root signs

Man, you know your maths and you know how to teach it! Thanks a million!

That flow chart in the beginning (1:30ish) is a really brilliant way of looking at it! Thank you!

i miss my most of calculus classes because i know patrick is gonna cover for me:-) thanks man...

patrick you`re the best dude.keep up the good work.

thank you for this, my teacher just gives up when the harder problems come around, this video is literally the only way i can learn this!

THE TREE DIAGRAM HELPED ME OUT SO MUCH, I CAN DO THESE WITH MY EYES CLOSED NOW!! THANK YOU SO MUCH PATRICK

i just love how you explain every video .... u make it way easier... thanks a lot

I like treating each component as a branch. That's a very clear way to think of it.

I've been struggling for this for a bit. You make it look so easy!! Definitely subscribing to this channel. Thank you, seven year old video!

panic!panic!i have my first calculus exam coming tuesday.thanx patrick for the good work you do

Uploaded in 2008 and still pretty useful in 2019. Please don't remove this video. I think people still need it in 2100.

Patrick JMT teaching world maths since forever :D

Wow, you are simply the greatest! If only all my professors were as good as teaching as you are.

OMFG, great video man, you just cut down so much studying.... thank you!!!!!!

Where were u these days sir!!!!!really made my day......easyyyyy

-Thanks so much... ''I'' depend on ''U''

Appreciate it mate, much better explaining it than my professor.

In less than 10 minutes I learned more here than I learned from my prof during the whole semester.... life is sad

"With respect to u."
NO. Respect to YOU, not me. You are a freaking lifesaver.

Dude u just earned my respect, and a like too!!

You're the best I don't know what else to say but I'll just say it one more "YOU ARE THE BEST !! "

Great video! Way better than how my prof taught it.

I bought a sharpie because of you!!

OMG UR THE BEST!!! U MAKE EVERYTHING EASY TO UNDERSTAND!! THANK YOU SO MUCH!!!

I LOVE YOU THIS MAKES SO MUCH SENSE

You have saved my ass on exams sooooo many times. Thank you

@n00dl3head happy that i could help you a bit : )

nah, just a normal guy making vids on youtube! glad i could help though : )

i appreciate the way you teach.

You Make It Look Sooo Easy !!! Amazing Videos Keep It Up !!!!

Wonderful job, made my professors scribbles on the board seem like chicken scratch!
Keep up the amazing work!

yes, you are just using the product rule in essence

BEST EXPLANATION EVER

بالعربي شكرا انت الأفضل انت ساعدتني بالرياضيات love you

You are amazing and I don't think you can hear that enough.

glad you like my videos :) come back any time!

nooooooooo way the second question was the exact question i needed help with, same variables and everything!

@bfferz in the second example he uses the partial of x to u because x depends on more than one variable, in the first example x only depended upon t so the derivative was used rather than the partial

Hi Patrick, Your videos are just amazing and is helping me to re-learn some of the basics after almost 10 years of no contact with maths! Thanks. Could you please double check the end part as I'm a bit confused about some of the partial derivaties that you did (specially with constants)? maybe I'm confused...but any help would be great.

bro you're my hero

This video helped so much. Thanks man!

Nothing against Khan academy... but I love your videos so much more!! Thank you so much for your videos

Saved my day once again! Thanks!

It's very helpful for me to understand backpropogation algorithm. That tree method is very similar to ANN.

Thank you very much man ! You are very good at explaining this!

i love all your video. you are awesome. all your video really help me. thnk you so much

you have no idea how glad i am you exist dude :'|

You are a life saver.

great work patrick

I'm guessing that it would just be so complicated with having to use the extended Product Rule. But I'd like to hear Patrick's answer, too.

Yes! That's clear. Maybe I was ready for it but you for sure trow light in my life.
I am ashame not to have draw the tree of implicit differentiation by myself :o)

@patrickJMT must be. Thanks for the help!

@MajinAmmaar no, not exactly; i assume you are in first semester calculus, so you are still doing single variable stuff; this has to do with multivariable stuff. technically this applies to what you are doing, but the general power rule is a specific rule versus a general procedure (which this is)

The chain rule for normal functions is for calculus 1 but this is multivariable calculus (calc. 3 in my U) so its a different chain rule.

Really useful and informative. Thank you!

Ur videos are really helpful!!

YOU ARE THE BEST !! THANK YOU !!!

This is awesome! Thank you for the effort! I kind'a feel guilty for not paying you.

Such a beautiful work i cannt explain here please expand this procedure...you are nice

Thank you Patrick!

excellent...... superb, outstanding, magnificent, highest quality, of the highest standard, exceptional, marvelous,

That's what I'm wondering right now. I think the best way to find out is to see if it gets the same answer.

there is a donation link on my channel page if you feel that bad about it... :)

I wish you were my Multi variable Calculus Professor.

@Dusevic magic!

you are a life saver! thank you so much

PATRICKJMT FOR PRESIDENT!

well explained .......luved it

... with respect to YOU!

is this really the beginning of calc? because it so, that's amazing.

Youre such a BIG HELP! Thankyou! THANK YOU!!!!

would love to see a second order derivative with chain rule!

thank you very much for this nice lesson

Thanks for the help!
