Calculus: Higher Order Partial Derivatives

[villex4]

DO YOU HAVE TIME RATES?

[LoztKauze]

your the best bud, these videos are amazing, cant understand my prof during class, come home watch your vids and everything makes sense!!! YOU ROCK

[mytwohands]

I know this is terrible, but I am nowhere near as worried when I miss my math class because I know I'm just going to come home and watch your videos anyway. It's totally enabling me, haha :D

[snake10566]

There needs to be more teachers like you.

[PepperOdor]

You seem to clarify everything that's foggy for me in these videos. These videos are treasures!

[Mantua64]

I already know most of the stuff that you explain from my former courses in math, but I still enjoy watching, since it makes me remember the material so much better!!

[midnightplume]

wow! it's blue!

[Armando17717]

You should get a fields medal for teaching in 10 mins what a teacher tries to teach in 4 hours. Thank you :-)

[patrickJMT]

@aeromech84 you are the 1,000,008th best comment-er, after many others :)

[halhauder79]

Thanks a LOT :)

[newsubject89]

patrick you are the mann!!! however i have only one concern.....do you have any videos on clairauts theorom and laplaces equation? that would help ten-fold.....thank you amiggooo for everything else.

[lobsidedballs]

I <3 you!

[jglee824]

the only thing i would do is show a graph and show what you mean by respect to x and y, the hardest thing about calc 2 is visualization.

[RaXaBBath]

Effortless & so relaxed. I would've never understood Partial derivatives if it wasn't for these amazing videos. BTW, u r an excellent teacher!

[patrickJMT]

@RaXaBBath thanks, happy that it helps!

[streetfyter]

Thank you so much

You are more helpful than u can imagine

[azlani92]

you should start doing live question and answer session for students. You are that good!

[tupacsomething69]

can you do a video showing applications of this?

[enjoyablesounds]

Deviding both terms in your final answer by 72..leaving you with ye^2xy+ xy^2e^2xy

This is not possible right? or else you would probably have done it.

[rolex408]

do u have an example of this but using chain rule. for example z=f(x,y) find second - order partial if x = r^2 + s^2 and y =2rs any second-order partial of f(x.y)

A left-handed math tutor. Hunh.

[Gilster85]

AWESOME VID! Thanx!

[nickohanlon]

thumbs up if this is your studing for a calc test!!!

[vivaswanv]

@nickohanlon what else would we be doing...

[JPraise100]

would it matter if you took partials of going left to right instead of right to left: for instance f(sub)xyz would the partials be the same if z was the first partial taken and the y or if x was the first partial taken and then y..

[patrickJMT]

@JPraise100 try it

[invariant144]

@JPraise100 Check out Clauriaut's theorem

[mb7733]

what are some applications of higher order partial derivatives?

[patrickJMT]

@mb7733 well, you use them to find maximums and minimums of functions (for starters)

[floopsie666]

@mb7733 wave functions as another example.

[anarchyrabbit]

Thanks for this vid!

[mielo101]

wow...this is confusing...i better revise differentiation of exponent again. but i get some of your teaching, what matters is which respect to what and which will become constant. thank you for the lesson. =)

[cooroxd123]

Hey do you have videos on 2nd order partial derivatives regarding the chain rule?

[sinaniso]

Thank you so much for the video. I just have one question, in higher-order partial derivative, shouldn't we go from right to left ? In this case it'll be the same. But how about if it's fyxx for example ! shall we do fx first then fx then fy ??? or we do fy, fx then fx ??

Thanks ..

[wxiao13]

thanxxxxxxxx

[whatisyournam]

u r the man

[TheArmud]

thanks very much

[alrasw]

hey patrick...where is spongebob?

thanks for the video

[patrickJMT]

@alrasw i got sick of his nonsense so i dried him out. now i use him to clean out my sink.

[laurenplakias]

umm thank god for you cause i cant understand a word my russian lecturer says

[Theincapower]

Hey Patrick,

I have watched almost all of your calculus videos. I am taking calculus III this semester and so far your videos have been great!

In other words, I know calculus because of you!

Thank you soooooo much!!!

[patrickJMT]

@Theincapower u r very welcome!

[dariog26]

@Theincapower im in the same position as you, and I as well have passed calculus (with A's in I & II) and its all thanks to patrick! Im in my third semester and planning on getting an A as well!

Thank you so much for all the help you have provided to thousands like me to get A's in math!!

btw im taking differential equations next if ur planning on posting some news vids on those, that would be awesome! :)

[tbabigal]

thank you for making these videos nd for ur help! God bless u!

[rose81br]

I'm not required to take Calc III, but am expected to use it in one of my classes this (my last) semester! This was so much quicker than sitting around trying to figure out what they're saying in a book! Thanks so much!

[StannyStone]

thank you so much.......

[GewoonVictor]

The page on your website doesn't link to this video (dead link) ;)

Great videos btw!!!!!

[dorood]

you could mention the other kind of notation too... the notation with the ∂ sign.... for example ∂²z/∂y∂x .... its more confusing but its the one we use in calc II

[Ducaale179]

The example did indeed make sense, and I do appreciate for your help.

[patrickJMT]

@Ducaale179 glad to help : )

[heydeniseison]

How will I survive without you when I head over to linear algebra?? DX

[patrickJMT]

@heydeniseison i would like to make some linear algebra stuff.... just not enough hours in a day.

i am trying to get my beautiful/amazing/math phd wife to make some linear algebra stuff. she knows it way way better than i ever will in this lifetime

[LonghornBabe11]

So my Cal III professor sort of gives us topics and tells us to "Google it" you are saving my life (and my gpa) with these videos. I owe you my passing grade, lol THANK YOU SO MUCH.

[patrickJMT]

@LonghornBabe11 ha, tell UT i want part of your tuition. since you are in austin, you owe me a beer for all my hard work : )

[xxxcoolboyxxx]

oh it makes lots of SINCE

[TajikThunderstorm]

so exciting to watch.. great tutorial.

[gundam2388]

Thank you!! your video was very helpfull.

[TheVkvkvk]

xellent .......i'd appreciate if you post a example for function of functions.

[sai1yzph]

omg...you are a genius

[SAS6774]

really helpful thanks

[76kookie]

Thank you so much!!!

[irfaanfr1]

Very helpful videos,

[ouzairhafeez]

Patrick ur an AWESOME teacher, God bless u man,Thanks!!!

froM PakisTaN

[atlroc99]

hey patrick thanks a lot for this video. it really helped a lot. Do u have any videos about "Increments & Chain rule" -two independent variables?

[juntran]

Your 10 min videos = 50 min lectures.

Thank you so muchhhhh!

[jamescboyd]

Don't know what I'd do without you... probably fail.

[blumpkin123456789]

YOU ARE A GOD SENT FROM ISSAC NEWTON

[JocoG23]

Very helpful videos, much respect for all the time and effort put in.

[pollardrho06]

Nice

[patrickJMT]

ehehehehe

many people complain at what 'terrible' teachers they have, but do not realize that teaching is harder than what one thinks!!

ask anyone to go to the board to present a problem and watch them spazz out : )

[dannyboy12357]

i know what you mean my professor "spazzes out" constantly.

[peyo001]

Patrick you are golden! It is always a pleasure to hear you explain this stuff in you clam and clean voice.

Thank you

[patrickJMT]

glad it helps : )

i just need some better lighting now : )

[stuttaz8]

you're a life saver ! I found your videos 2 days ago and have been addicted ! They've been very helpful !

[Mattprole]

Going through the algorithms are great, and I'm sure plenty of people appreciate it, but I'd also like to see a few videos (maybe even a series!) on the interpretation of the meaning and purpose of the math discussed (perhaps a few derivations). I'm sure plenty of people would find it very interesting.

[insignificantgirl]

ABSOLUTELY USEFUL!! thanks a bunch!

[8888Duke8888]

always educational and well thought out!

[loper9]

Im sure all of your guides will help me next year in high school. Eeek. Im sure ill be back to check out your videos for help. I know you helped my last year, so thanks again.

[grandopening]

Good video once again Patrick !

[patrickJMT]

thanks : )

someone asked for it (or close to it), so here it is!
