[xheather492]

I'm shocked as to how calm and organized this calculus professor is, lol. Mine writes very quickly and sloppily.

[TheEpicflyer]

awesome math sifu...thanks!!

[thatstits14s]

WOW, math made simple is a bit of under statement.

[lubime10]

The best teacher of the whole world !!!

[MrSpacenid]

in 14.22 minutes i learned more about Derivatives than i do in a 2 hour and 45 minute class very sad day :(

[iMSWEetBROyall]

@MrSpacenid Holy fuck, your classes last 2h45m?

[EvaSlash]

@iMSWEetBROyall that is nothing. i take my calculus class on a saturday , and it is 4 hours.

[ThePinkFlamingo305]

@1:29, i dont get the exponent rule some1 helpp :(

[urtziizotz]

@ThePinkFlamingo305

Exponent Rule: d/dx[x^n] = nx^(n-1), where n is the value of the given exponent and x is the given variable.

So, for F(x) = x^2+3x-4, you derive each term. d/dx [x^2]=2x^(2-1)=2x, d/dx[3x]=3(1)(x^(1-1))=3, and d/dx[-4]=(-4)(0)=0, and thus F'(x)=2x+3. The same rule works for the other equations, too.

I'm also bad at calculus, so I had to ask for help. Yay 50 year old textbooks!

And thank you for the videos, MathTV! They help a lot.

[ThePinkFlamingo305]

@urtziizotz thank you

[RepresentinTX]

@ThePinkFlamingo305 Say Thank you to him...

[Equifish]

So the derivative of a Sphere's Volume is its surface area? Damn!

[NothingAtAllXD]

Your junk compared to Khan Academy, leave.

[scottdylan20]

@NothingAtAllXD Why should he leave? He's helping you for free, appreciate that instead of posting retarded comments.

[hiphoppacmotion]

no way would i consider myself smart.

[hiphoppacmotion]

I passed single variable calculus (this past quarter in college) by only going to my 2 midterms and my 1 final. I didn't go to one class....(i know that's bad). the weird thing is, almost half my class failed, so it gets me wondering how i even got through even though i taught myself everything i needed to know...

[1992photographer]

Calculus is fun! :D

[jeffdadude87]

If I get better at this in the next 10 years, I intend to visit several 1st grade classes and give them 45-minute lectures on this, that is if the teachers will tell me it's okay to do.

[GJeet92]

you my friend are the math god



[conniechiang]

hi, could you show me how you would mulitply it out if you have a root or fraction exponent and if it is the reciprocol, ie: 1/x or 1/root of x ?

[pmoore158]

This really helps. I'm in a university right now and i don't have a single class or professor without a language barrier

[Kininet]

You are great. Thank you for your help.

[n0d0ubt007]

I hope my teacher reads this! This is how youre suppose to teach! Damit!

[darkprincess044]

oh i see!! ahaha.. thanks for that.. im absent when my teacher taught this to class.. hehe

[darkprincess044]

how did you get 2x when you differentiate x squared in the first problem... im just confused...

[malikannas786]

@darkprincess044 by using "Power rule" on x^2

power rule: nx^n-1

[mung0jerry]

@malikannas786 Actually, nx^(n-1) would be the correct notation, otherwise it would be implicitly construed (correctly) as the quantity (nx^n)-1.

[malikannas786]

hey teacher..... why you write (16) at 3:30 when you apply rule in EXAMPLE NO 3???? i cant understand this ..... anybody help me???? plz

[argstupidcomputer]

@malikannas786 Because 16x is in parenthesis, you need to differentiate it so you add another (16), if there where no parenthesis, you wouldn't need to differentiate so 16x^3 would be 16(3x^2)

[mung0jerry]

@argstupidcomputer You multiply by derivative of 16x using chain rule, which is 16, not add another 16: (16x)³ = 3 · (16x)² · 16 = 3 · 256 · x² · 16 = 12288x²

[Snoopa90]

thats my nigga right thur!

[mollie1507]

I need help, the last function, when you get to 6(9t exponent -10), how come the constant is the factor in front of the parentheses? While in F(x)=(16x)exponent 3, the 3 in the derivative is the one in front of the parentheses?

[stefietube]

thank you so much for posting these videos! i really appreciate it!

[impavitus]

Sir, I really learned alot about from your video, thanks.

[atimor]

hi the function f(x)=e^(sqrt(x)) is defined when the x is equal to 0. the y=1. however the when i find the derivative of this function, i get: (e^(sqrt(x))/(2(sqrt(x)). at zero, the derivative is undefined. i am unable to answer the question of why it is not defined. im in calculus 2 in college and i was reviewing some derivative when i encountered this situation. any answeres as to why the derivative is undefined at the same point where the function is?

[speedysavant]

An excellent review of the basics sir :) Subscribed, and I will be distributing these to all my math-interested friends!

[vano512]

Ground braking! Thanks a lot!!!!

[versedaaron]

11 people are math teachers that are upset that he is better than them

[patrick42h]

I wish I had known about these videos 3 years ago. I failed Calculus I and I got so discouraged I changed majors.

[MikSane]

free youtube in a few minutes versus 52k a year to have some hindu attempt to teach me stuff...WOW!

[alberticoman]

YOU´re good i mean how can be posible that some people dislike this incredible., INCREIBLEEEEEEEEEEEEEE

[jonyb0b13]

Wow you just explained everything my teacher tried to force into my brain in 5mins....you sir are a beast

[fulouzero]

The beginning ambient noise is ominous. I felt as I was gazing into the abyss surrounding by flowers.

[zayaspablo1]

i hate that im paying so much money of tuition and have to come to youtube to learn everything way easier.

[Cavin21]

@zayaspablo1

technology has changed everything, you don't need to pay so much for teachers who barely even care to teach you.

[dedn1994]

Thank you!!!

[BBINGHAM032352]

He makes me realize why I loved calculus so much. He teaches with clarity. Does he have videos for applied problems involving both differentials and integrals?

[ekidz220]

so why didnt you use the chain rule for the last problem?

[Nightmare365wj]

@ekidz220 exactly i dont know either someone please please help

[ladymusiq]

I second wickedfunny, you teach way better than my lame teacher, who has convenced herself we're all teachers just brushing up on the language of Calculus. My teacher has the problem of switching inbetween [ f '(x)=y'=dy/dx ], which makes figuring out these problem a real brain buster.

[hiphoppacmotion]

how do i survive college math when there are soooo many stories about sucky professors that are hard to understand??

[ZalvorKrunix]

you suck

[aquamanxz2]

thanks alot ur much better than my teacher

[Caonex2]

thaaaaaaannnnkss

[mateo642]

Isn't the derivative of a content equal to 0?

[superjokerrr]

@mateo642 its "constant"

[mateo642]

U got good handwriting

[deathtoy101]

what???

[Superdeduper739]

ill wait until at least algebra 2 for this.

[murmaider668]

great job!

[hiphoppacmotion]

so how much harder is calculus going to be in college if you did well on the ap ab exam in high school???

[wiz126]

@hiphoppacmotion haha, high school ap calculus is bs in comparison to college calc, trust me =)

[hiphoppacmotion]

@wiz126 ..............0_0..........tha­nks for scaring me. how so though?? i really really hope i'm prepared my first day of class

[shounenLove]

i thought V' = (4/3) pie 3 r^2 r'

[Jbrouhaha]

@shounenLove The derivative of r is 1; therefore, you don't have to worry about because it doesn't affect the problem. For this kind of problem, you don't need to use Chain Rule just yet.

[rahulmisra2000]

Excellent !!

[Falahim]

i am only in 8th grade and apparently learning calculus at home and these vids are really helpful. Thank you for posting them

[TheAlek033]

@Falahim same but im year 7

[FantasySycho]

put a Q between the words you and tube and then press enter or click go" When you are finished, check your email!

[Nile505]

"times the derivative of X with respect to X with is just one" This is because you are substracting one from the power and moving it to the front basically? n-1 so for the 3x term only you are taking X^(n-1) = X^0=1 so 1(3)=3 ect? He doesn't break down his steps well. goes a little too fast.

[1SavageDragon1]

your a saviour :D, can I have your autograph o_o?

[jamestrowa]

Ta very much. Very helpful to see how it is applied with the examples

[Go20002]

keep it UP..

it's really helpful

thank YOU :)

[Erobeashema]

So why does the Universe exist?

[msopy]

great stuff. i'll have to tell some of my classmates!

[wickedfunny]

thank you so much, i was failing calculus until you helped me out with your amazing videos. do you have one for piece-wise functions, you teach much better than my teacher

[a8514122]

@wickedfunny totaly agree with you!!

[2glam4aUsername]

what the hell are you talking about???

[djpatonics]

i think he needs to stop saying with respect to x. after the first few times i think we get the point

[nonaubizness]

Yes young skywalker, your teacher is being tedious! Have you not noticed a trend that when first pricipals become ingrained enough, a new rule is derived to cover entire classes of problems, so first pricipals can be left behind, and new understandings can be forged? If your teacher clings tenaciously to something like "WRT" long after it has reached its sell by date, you can bet your ass there is something even more difficult to understand waiting in the next semester like... d/dxdt

[teasermaniac]

sooooo easy i swear, i am in year 10 and this is so easy for me :P

[Sector9pablopedro]

you're cool

[tyler1ross]

............. wat?

[aa3gunner]

same reaction here....hahaha

[SumRandomDude]

I think I could be able to A my class now lol

Thank u very much.

[inyourface522]

thank you

 so

much

[jiraiyamandaraya]

thank you sir! helps a lot. =)

[DoCWaSaBe]

thanx again man, nice and very easy

[vincethemann]

before watching derivatives 1 from 0 and .5, they mean for you to watch the chain rule videos

[mshgraham]

I just took this course and oh my LORD it was tough. I passed it though with a B-.

[jeffrey321]

to diff F(x) = (16x)^3

I think take the constant out would be easier

because sperate the constant and variable will make the fuc more clear

sorry for bad english

[FJaccoud]

Chain rule.

[wontonchewer]

AHHHHH!!!!! MY BRAIN HURTS!!!!!!!

[LeeDiddy990]

excellent teaching method I think teaching just theory is not enough. you also have to explain through examples. that's what many university professors don't do its not their fault they just don't know how to teach in an educational fashion because they teach basically how they were taught in college. I made an A- in Cal I because I busted my butt and looked for help. thank you so much for making me appreciate calculus. Im now going into chem. engineering because of you.

[Yip1991]

2:44 when he canceled out those 3s i was like OH SHIEET

[soldierwife1234]

im going to school to be a social worker, and i have to take calculus class, it makes no sense!!!!

[jacobbis4lovers]

A lot of degrees these days require calculus.

[konohasugio]

I'm just watching these videos before I begin learning it at school.

Amazing teaching skills. It's nice to have a 'tutor' to brief me on calculus before I begin my final year.

Thanks for posting this up!

[theGP313]

scrub stuff

[lee2575]

Sensible use of the net!!

[Thrawst]

this is what the internet is for!

this has helped me soooo much for my differentiability and derivatives test.

thanks

[wexarexthexStorm]

so awesome

thanks.

[SerbianGangsta1]

good video!

[imjohn007]

math tv rocks. thanks for help man

[adamthelover10]

thanks for taking the time to help us :)

[PhilMarl]

just wanna say thanks this video help me alot ;)

[kimihanif123]

great video guys

[themarman]

Great refresher thank you so much.

[CelticFCfan18]

thank you so much i really appreciate this

[larry89]

Yo.. MATH TV.. I LOVE YALL

[sarr47]

good this is what we need on youtube not the other bull shit.

[sheerin15jon]

This guy can actually teach! my professor just talks to the board when he's writing lol

[crazygurl45]

this is so much easier than that stupid formula! thanks so much, my teacher isn't very competent and this helped an enormous amount, thanks again.

[yobbleyobble]

thank you very much! This video was very well explained and your thoughts are easy to follow. I wish we had more teachers like you in our public school systems.

Thanks again

[mido176]

i dont understand the (16x)^3 ... how is it 3(16x)^2 (16), shouldnt be 16x 16x 16x, then deri. of that is 16 16 16 so answer is 4096

[cubencis]

x^3 wont get rid of the constant-x in one derivation;the reason for it is b/c of the method of derivation: basically, if anything (16x)^3,can be represented as (16^3)(x^3) then deriv (3*16^2)(3*x^2)= but he does the same thing, though with the distributive properties of 3. so, that 3 (in the vid)represents 3*16 and 3*x because of distribution... if u ever see urself answering a question like that with a large #,remember that deriv's are all about slopes,1 deriv will keep the slope or be similarM

[cubencis]

and not suddenly become a slope of 4000/1

[mido176]

idk for some reason iam not getting it ;( like i understand everything just not that one could u plz explain it a little more ..thankx so so much

[superhornet59]

It's a shortcut to find f'(x)

basically, you have f(x)=x^n, and f'(x) is nx^(n-1).

Watch it again and you'll see how that makes sense. Why it works that way? beats me. I'm just glad it's there.

[jaypeemantuano]

thanks a lot..you help me understand calculus a little bit..wish to master it..lol

hope to pass my exam now..^_^

[jacobbis4lovers]

Did you pass?

[jaypeemantuano]

honestly i didnt pass the xsam..but i did pass the subject.lol!

[jacobbis4lovers]

Well, at least you passed the course, right?

:]

Did you not study or something?

[jaypeemantuano]

your right..im not studying my math subjects cause it gaves mee too much headache..lol!

_cause i keep on asking my self why do i need to study those math problems and also physics..i wont use that on my career..im planning to take computer engineering..where will i gonna use it?!lol ^_^

[jacobbis4lovers]

There's a lot of math in engineering, though. Maybe not calculus, but probably differential equations.

[tennisIS4pussys]

dam... u make my teacher look retarded. U explain it so well

[BlackMazeGod23]

I DONT GET THIS!!!!

GOD!!!

[BlackMazeGod23]

wait polynomial i learned that the exponents (little numbers on numbers) have to be added near the one and see which is bigger 5<6. 6 is the answer. if there are no exponents that means it's 1

[hodosoko3]

i hav an IB exam tomorrow...didnt know anything about differentiation...now hopefully ill pass...loll!!:p

[h3n7yw1]

wow Santa thank you very much for ur explanation i am an electrical engineer and u just cover in two minutes what a professor couldn't cover in two hours and I actually learned something lol

[fatboyslim4000]

thak the lights something to finally help me study

[Shadyhunter04]

I wonder if he gets his teaching powers from his white hypnotic awesome eyebrows.

[Shadyhunter04]

[x4812k]

hahahaha nice

[Shadyhunter04]

This man just covered in two minutes what it took our TA the whole class to explain.

[Shadyhunter04]

This man just covered in two minutes what it took our TA the whole class to explain.

[supersonic6]

I acually Learned!

[sharktry]

thank you very much I have done quantitative methods in finance and the professor did not explained as you!

[livingonfaith854]

wow! this is such a big help!!!! thank you, whoever you are, you are a blessing!!!!

[12ig0]

lol... whoever you are... thanks for making me laugh...

[sajeeshd]

Nice.

[chubbygrape]

thank you so much!!! this really helps me get through my course

[kantana1022]

omg you are the santa claus of math

[mariacake88]

so my teacher made us learn the difficult and long way of finding derivatives, and he said as soon as we get the hang of it, which i never have, he would show us the quick way.

well i guess i cheated because you just

taught it to me:]

and it helps soooo very much.

thanks!

[kjc121]

awesome videos! i just started calculus and this is really helpful.

[Meyanfien]

Great Job. I love ur teachering

[alednam]

thanks a million please keep posting

[arfanrasul]

Thanks lecturer for upoading this video! Very beneficial! Helps me in studying AS level in england!

[liljones28]

i really wish this was my teacher...my teacher told the class he didn't care if we passed or failed and that's exactly how he teaches class...like he doesn't care!

[MathTV]

Juan, I teach college, but most of what you see on here is also taught in high school.

[momoon07]

@MathTV thanks aloooot ...

peace and respect to you from me from Saudi Arabia ;)

[boquensejmc]

Hello there I'm Juan from buenos aires, argentina and i'm studying to be weatherman.

I would like to know if that's part of college education in the usa.

I need to picture how is education in argentina respect from other countries

[ShaIIowfu]

I dont know who you are but I watch your videos everyday. I do mean that. Thanks!

[salt007]

What you are doing is helping people understand math better. It actually makes it sort of fun.

[ShaIIowfu]

Incredible Penmanship Sir!

[NetDialect]

When can we buy the pre-calc and calc CDs from the site? I'm a subscriber and about to move into pre-calc next semester. I would love to see the same kind of flow as your Algebra II lesson CD.

Thanks a Million Mr. McKeague!

[twil05]

God Bless u my teacher cant speak english that good

[homedogdigity]

same here, this helps. Awesome job!

[drcluk]

holy moly this guy is amazing. i wich my teacher could explain things to us...just once...
