Adv Diff Calc 1: Partial Derivatives review

[browno26]

i cant believe 15 ppl dislike this, i think they are just stupid and resentful and/or racist

[12Alforja]

Thank you so much Donylee for your help and wonderful lectures. Just only one thing and is try to speak more slow; speacially for all those students, public that English is not the first language. God Bless you.

[webmastertool]

@12Alforja chances are he doesn't believe in god. nice try.

[20minutebreak]

nice graph!

[smoke9206]

jaaa pierdole nic nie rozumiem. Po polsku nie kumam a weź obczaj taki motyw jak po angolu nawija ziomek.

[YoMomSaddam]

I want you to be my professor for every other math classes and stats classes I need to take. TRANSFER TO NCSU!

[PoleReseal]

Good Stuff Dony, cheers! any new videos coming? analysis?

[444zane3]

hmm....i agree as well......rather shallow and pedantic

[friedjelly10]

you're good. thanks

[friedjelly10]

you're good

[88edc88]

Master!

@88edc88 my bad I meant to thumbs up this lol!

cool thx

Not many of you may know this, but this guy is actually Flash the superhero.

[avatar098]

i don't understand anything youre saying! but i'm watching just for the fun of it(:

Chekup Malayu?

[WTFirfan]

He's rippin up the mic yo!!

..on a serious note, this was very helpful. Thanks!

[sarafann]

maaan your insane! you taught me everything i need to know and gave me basic kung-fu lessons AT THE SAME TIME! :) ty! :D

[buddydog1956]

holy shit! this guy's a riot! slow down dude, will ya ~ !!!

[melbourneopera]

So how to combine two partial functions of fx and fy to find the tangent of xy plane? I really forget that.

[sarahannstarmer]

Thank you for the help.

[goraltch]

your intersects of the plane z=f(x,y) and x=x1, y=y1 look really weird. It can be confusing, the first curve should end much higher, and the second curve should be convex and not concave the way you drew your plane. Otherwise a good video.

[saifrizwan]

Thanks a lot. Your videos have been very helpful.

[rollininoldstyle]

this guy is seriously styling in his videos. man i should get a coat

[cesfigas]

the Bruce lee of math lol.... nice mooves there!!! tranks alot!!!

[RomanRomp]

Great video, very helpful. One suggestion I have: when dealing with Youtube, it can give a very grainy video so please make your equals signs very different from your minus signs - it's easy to get them confused when they are drawn small.

Thanks very much :)

[hybridindian]

You sound like Bruce Lee.

[migmob27]

I love partial derivatives, I wish I was studying this subject again, I hate my new classes.

[hefresh2def]

This fool is crazy...I'm out....JK, I'm just dumb ass hell. I wish I could get past algebra.

[djkadirtube]

super teacher!

[alcideslugo]

Thanks again for keeping this space of live knowledge in internet!

Love from Venezuela!

Leaving many unteathered is dangerous to a whole system,As one well knows now.Partial Derivatives review.

I derive there are many dangers.

yes?

You are really good:)

[uniterscron]

I pity your limited mind. You don't travel a lot, do you? You have no appreciation what so ever of other people. I guarantee you if you explore the world more, you won't think this way again. Appreciate life!

[mike4ty4]

"I pity your limited mind. You don't travel a lot, do you? You have no appreciation what so ever of other people. I guarantee you if you explore the world more, you won't think this way again."

I can't explore the world like that, yet I don't make rude comments. (I don't have the money.) The key is to have better morals, and more light in one's heart.

[uniterscron]

Do you have any idea what Marz2081 said? Please don't take my comment out of context!

[mike4ty4]

"Do you have any idea what Marz2081 said? Please don't take my comment out of context! "

Yes, I do. I don't "excuse" what he said, you know.

[mike4ty4]

I just was pointing out that it is asking what may not be possible, and is not necessary: one doesn't need to do such difficult things just to see the wrongness of making such comments.

[kinnala]

Thank you very much! I was earlier aware of that max/min of a plane (3d) can be found when both partial derivatives are zero, but now when you demonstrated the concept of partial derivatives so well, I was able to figure out the idea behind it.

[mgmoeab]

anything on cuadric surfaces?

[imnoobish]

he's high on numbers.

[doseryder]

He really shows an incredible enthusiasm for math

[MRburitz]

I wasn't that scared of epsilon delta approach.

[soulreaverdoug]

that´s where limits theory begins

[MRburitz]

But we started learning limits during the definition of derivative. Should've taught us the theory first

[soulreaverdoug]

got a point, i learned about limits first than derivatives cause a derivative of a number it´s a limit approach of delta X and Delta Y, u are right

[jishuenkam]

epsilon delta approach is fine once the concept is clearly illustrated on the graph.

but it is always taught later than topics such as derivative and integration.

IMHO,it should be taught before the normal limit theorem since the epsilon delta approach is indeed the precise definition of limit

[soulreaverdoug]

can you CC for impaired people!!?

[smithraymond]

For some reason I always found Pre-Algebra the most difficult of all my math courses (repeated it THREE TIMES!!!). After that it all seemed to flow like water. Weird!

[soulreaverdoug]

that´s the base of all math, it´s like to learto drive a car once you get with the trick, the rest is easier

[jacobbis4lovers]

Yeah, every math course has a little bit of algebra in it, even calculus. So once you grasp the basic concepts of algebra, you should do fine in harder math courses.

[negvey]

haha im barely passing my Core Geometry... You are smart dude :D!!!

[kakashi1992]

wow- this is so interesting!

thank you! (p.s. I'm currently enrolled in calculus in one variable)

[poserlooser]

Thanks! This is a great video.

[ZB90]

These are going to help me fix my many of sleepless nights

[donylee]

Good good.

I'm about to upload a whole new bunch of this 'Advanced Differential Calculus' videos.

Stay in tune.

[elfili77]

@donylee im a non math major....but my work fell into teaching physics and it requires that i should be well versed in calcu.... will a non math major guy like me lear calculus in mmonths ...thanks and Godbless

[libardogonzalezalvar]

THANK YOU VERY MUCH

YOU ARE THE BEST
