Local Maximum and Minimum Values -Function of Two Variables

[Jennifersmith1596]

i dont get this. -__- im stupid

[TestMonkey254]

YOU ARE A GOD seriously my calc prof isn't even this clear thank you!

[litolpnoy]

I don't understand why Calculus teachers can't teach like you. Don't know why they makes things so complicated, yet you make it seem so simple =\

[Sectorsophia]

Thanks again!

Does anyone know in what cases do you use the Hessian matrix to sole for local (relative) max and min?

[mooglexkupo]

WHO WOULD DISLIKE ANY OF YOUR VIDEOS!!! D: <

I'm in love with all 941 of them.

Well, at least those that i have viewed so far. :D

[Sypo7]

I don't get how fxy equals cos(y) :/

[mariomaruf]

They're advertising female cycle control drugs on your videos.

[Codyje]

Fantastic!

[ismekin]

thanks alot! btw do you have any videos about absolute maxima and minima on closed bounded regions?

[patrickJMT]

@ismekin yup

[bboydjoe]

@ismekin yea that would be using lagrange multipliers

[88omarz]

hey can you do this question

3xy^2=2z^3+2y+5

i need to find gradient determind the critical points and sketch the curve

[omarommg]

what if D = 0, I know then I can't use the 2nd derivatives test so what do i do?

[Childsd]

You have really good handwriting. That is all.

[patrickJMT]

@Childsd glad the rest of it what i have sucks

[Childsd]

@patrickJMT haha, not what I meant. I'm planning on spending about 8 hours total today studying alongside your videos. So to be clear, it does NOT suck! Just admiring good penmanship

[o0xAngelinax0o]

@patrickJMT I love your sense of humor.

I think this man deserves and should receive profits from Youtube.

Probably he receives... I hope.

[lisinka3]

Patrick, is there is a similarly general way to optimize a function of more than 2 variables? Or would I have to use a computer?

[johnwagu]

you save lives

[vabs9211]

excellent mate!

[lisinka3]

What happens when you have a function of n variables, where n > 2 ?

Thanks.

[mrana14]

exlnt sir .heads off

[mrana14]

thanx a lot.you are better than my prof million times

[moaf06]

thank you man, you made my life easy :)

[yoyaya007]

thank u man this is very helpful especialy for students like me that do not go to their courses!!

[bouk98765]

thank you very much patrick

your a math guru:)

[dtodak]

I'm here in Ireland, 2nd yr electronic engineer in college, have a full exam on this stuff.. gets tricky with curves and paramilitaryising (sp?) anyway. although your clips are "basic" as far as the maths test i have coming up. They are extremely helpful, give me a better understanding of the basics, and more times than not, the basics are more important than the not so basics.

Go raibh maith agat :)

[patrickJMT]

yep! if ya get the basics, the rest is easier

: )

[Okami87]

good job very helpful!

[gulipunji]

patrickJMT, I love your videos they are great but what happened to your website? I tried to have a look at it today at 6pm 8/2/08 from Singapore but my internet explorer can't show the web page. I would love to be back on your site, keep up the good work:)

[patrickJMT]

dont know what the problem is... the website is up and running to me?!?! : )

[patrickJMT]

youtube had a note that youtube links from other websites were not working for a few days for some reason, but are fixed now, so i guess that was the problem. the website should be ok now! hope things are ok in singapore!! ( ps i would looooove to visit! : ) )

[Nandine2]

great video

[patrickJMT]

thanks!! : )
