Calculus: Derivatives 0

[MrLYTRIX]

FAAAAAAAAAAAAAAAAARK man i actually understood calculus!!!

[kram146Mark]

I'm learning Calculus for fun, I'm only taking Geometry right now. Main reason actually is because I'm taking Physics and there's a concept of integrals that we solve very basically, I want to actually know what it is.

[ManDudeYeah]

This video is very hard to masturbate to.

[nellajayec]

Thank you very much! God bless!

[bflatism]

Holy ship! I took calculus twice and failed it. I wish I knew about this video back in 2008! I might try to take it again!

[thatstits14s]

simply brilliant



[jakethesnake576]

I used to love physics, algebra and even a bit of trig. then ran into a long run of bad teachers and tutors who made me dispise it. Saw this video while studying for a calc test and the spark is alive again, math IS practical, and when explained correctly it becomes very clear and easy. Thank you, this really helped me

[jhnb91]

The guy that made Calculus fun for me.

[8mariarichiez8]

Wow! Now i get it!

[xXTheDeathReaperXx]

Best maths teachers ever, where do you teach man? Your students must be really lucky!

[thunderkaiz]

If you are my high school math teacher, I'm willing to stay after school for hrs just to do math with you. Simply incredible

[71DavidSam]

If you like this you guy you have not seen anything yet. Check out site khanacademy org.

[8mariarichiez8]

@71DavidSam khan is pretty good...but in the end he ends up confusing me...=S

[binzsta21]

i wish one i could do this..looks so kool

[Avatar230594]

Hey man, Please do a conics video.

[kauxkaux]

Top Notch explanation! Thanks!

[dipy370dxl]

thank you Sir

[MrSmithm3]

What a Lad....



[Hengx9]

I owe you a big one, sir.

[MegaAnnoying1]

It's Lopez Tuero!!

[enlargemedia]

Which notation is lebniz notation and which is newton notation?

[tuxv]

@enlargemedia variable with a dot on top of it, is the newton notation. like, say, distance is x, x* for velocity, x** for acceleration. Lebniz is using dy/dx as far as I know.

[TheRPG1111]

i wish this guy was my teacher

[Rayden150]

you make calculus look so beautiful

[Bondie11]

im paying roughly 500-600$ to be taught this in college, and my prof blows and cant teach to save his soul. Not that class average of 50% means anything,,, I just learned more watching this video than I did being 1 month into my calc class. Wish I found this sooner.

[brettbed]

That was amazing! Brought it all together for me : )

[tubertomp]

since this is strickly for 12 year old noobs maybe you can use x1

[casper1918]

Now I see how lacking my high school education was.

[G0DofRock]

wow.....that was way easier to understand than the way i learned. Its nice to finally know HOW you get the definition of the derivative by deriving it.

[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?

[autumnreign86]

omg.. Why can't teachers learn from this guy... he makes it very easy to understand..

[Alex1984Z]

And yes, my prof sucked. He was a genius and nobody, not even the people who were good at math, could understand his lectures. Thus I rather learned with your help and my my own brain.

[Alex1984Z]

You helped me to a C on my university exam with two weeks of learning. Thank you very much for that. Untill then I ALWAYS, since my childhood, been a student who was happy to not get an F in an math exam.

[49fiori]

FUCK GOING TO SCHOOL! THOSE COCKROACHES THERE DON'T KNOW SHIT.

I'll start writing in my resume Education: YouTube University

[chintoo266]

Alas,,,,,if i had approach to these videos when i was in college, i would have scored much much better in calculus..........i wish some time can drag back and i may re-do my Bachelors with these videos.......i must top ..........no one taught derivative definition like this atleast to me

[machrpr]

im a senior in high school this year and i was always bad at math but now i totally get it now. he is awsome!!!!!

[TrueDiligence]

He makes me love math. He makes something so complex like math, so simple. Incredible.

[many9662]

I like this video. Thank you for your sharing. Hope to see next your video.

[MrSunshine124]

@imaginationgal I didnt take this until my fourth year of highschool. it is ussually one of the last math courses you take in highschool

[2502a25]

faultless I love you.

[SuperGuitarman69]

Man I wish you were my teacher back in college. Outstanding sir, simply outstanding

[alberticoman]

how can be posible that 7 persons put a dislike what an assholes.. this is a incredible VIDEO. congratulations buddy. you´re the man

[TxJamesxT]

Acing my math quiz tomorrow with this. AP Calculus ain't got nothing on me.

[lastdayshining]

Thank you so much. Because of these videos I'm actually starting to understand whats going on in my Calc class... thanks again!

[johnshepherd2011]

what is the derivative of yx^2 and xy^2????

[mfaure420]

He is amazing. I would love to see his feelings on the economic recovery cycle using the sum of data from all recessions since the crash. I bet he would nail it.

[presbarkeep]

omfg this man is a professional brain exploder. US GOVT COME GET THIS GUY!!

[presbarkeep]

wtf is a derivitave?? drive-ative? de-rivative? green shrit man, i have no idea what u talkin bout. :( i feel stupid and uneducated now.

[JonathonRedley]

@presbarkeep

It's Calculus. It isn't taught until college. Sometimes 12th grade, depending on the school.

It takes time.

[harwoodgirl]

@JonathonRedley we are learning it in grade 11 at my school

[ckala13]

@JonathonRedley Some schools allow their students to take it earlier than that, if the students are qualified for it. I have a friend who's taking AP Calculus as a sophomore and will be taking college math courses outside of school once he finishes the year. 

[MrReymark16]

ganun lang pala kasimple un eh!!

ang dali naman!!

[gabri888777]

You are simple the best math teacher in the world!!

[bossplaya969]

that was wicked help me a bit lol thanks

[idontevenskate]

I can't say thank you enough. THANK YOU! I've never seen such clear writing and had a straight-to-the point explanation like this.

[iamtherhino]

Thank you for posting these! It is difficult to see what the professor is writing on the board in a crowded class so this is a huge help to me! I have found these on line lectures as valuable as tutoring.

[AlbanianBro]

I Love you man!!! :D Thanks to you i will pass all my math exams!!!

[bsivoljr]

Great!

[ISyriZharriI]

Thats a great job you are doing by posting these videos in youtube, they are really helpful. :)

[grounnyJr]

I liked the last smile! :P

se ve muy lindo....

[nVsNeVeRsCaReD]

What is the definition of the derivative... This has actually helped me learn more about derivatives BEFORE I start taking calculus. Thanks you!

[djdeluxe76]

He just explained, clearly, in 6.23 min what took our math teacher two whole lessons at least. And our math teacher was a good teacher. I am long out of school and I never would have thought that I would need any of this again. But here I am doing 3D and I wanna write a little plugin and suddenly I need to know all this stuff again... so pay attention guys and gals... sooner or later you will need it! :)

[Subaangen]

John Lock (Y)

[pythor2]

Thanks. Are you superman??

[arumugamyau]

Thank you so much for your wonderful mathematics lessons. I wish I had a teacher like you when I was at school :) I was always interested in mathematics but there was no one at school to inspire me. Instead of studying maths and physics I studied medicine. Schools need teachers like you. You are indeed an inspiring teacher, Sir ! All the best!

[raynez]

what if h=0??

[bryanhonc91]

@raynez h cannot equal 0, you will have to look into the proof for that. But in short, the definition of the derivative is that limit, as shown in the video. The limit as h approaches to 0 is, graphically, two points x and x+h coming closer and closer together (distance between them approaching to 0), and thus farming a line that connects these two points will actually give us a tangent to one point (since the distance between these two points is infinitely small, approaching 0)

[bryanhonc91]

@raynez to continue, if you were to make h=0, there would no longer be two points, x+h and x, but rather you would have two of the same points, x and x, which will not provide you with a tangent line ~ the point of the derivative is to give you the slope of a point on a curve, and that is the beauty to this, by assuming 2 points that are infinitely close together, u can form a tangent line which you can find the slope of ~ rmb, drawing a tangent on a graph paper to fin the slope is not accurate

[hoffman164]

you can tell he has been doing this for a long time because he draws straight lines on a black board. this is only attainable through experience haha.

[tehs4ndman]

idk about u guys, but i cant stop staring at his eyebrows... but his tips do help a lot

[julianchemist]

I learned Calculus at my University for my Bachelor degree in Chemistry, but I have never seen a more clear and precise professor like this man. Congratulations, professor. You are the best and most dedicated Calculus professor in the whole world. Keep going, you are contributing a valuable resource for all the Calculus students around the globe. Perfect!

[GeneralOJB]

Isn't the graph thing integration ?

I thought differentiation was slopes and integration was area...

[gmsherry1953]

@GeneralOJB You're right about differential being slope and integration being area, but a graph can describe them both. If he was talking about the area under the curve, that'd be integration. But he's talking about the slope of the tangent to the curve, and that's the differential.

[Falahim]

thank you sir

[lubime10]

You are really excellent Teacher.

This was very clean and clear.

Sr. Thank you very much.

A+++++

[ni3dzi3lski]

thank you.

[EricEngland]

My head almost exploded...anyways, does this formula have anything to do with those Wall Street derivatives that nearly took down US banks in the 90's and the recent fall of the housing market? I still don't really understand what a derivative is btw ...lol.

[gmsherry1953]

@EricEngland Clever question; I'd never noticed the similarity in the terms. In both cases one value derives from another, but the formulas are not related. In math, the value of the derivative comes from the slope of the function. In finance, the value of the derivative comes from some other investment.

[HanYoungsun]

I'm not good at English nowdays, so I will study this lecture when I become good at English.Thank you

[janno70]

@HanYoungsun hi! where u from? im from the philippines a civil engineering student,.

[HanYoungsun]

I'm from Korea . Nice 2 meet u.

[janno70]

what course you are taking?

[TheSean925]

thank you green shirted man, you recieve # of stars > 9000

[steve492]

Is the sound broken or is it just my computer?

[CallMeCapta1n]

Sound for the video is only being output to the left speaker / left output device.

[spiceb2008]

mine works great

[HairyPotter2006]

this guy is excellent!!!!!!!!!!! 100 stars!

[loves2dance36]

the visual interpretion helped me understand a limit for what it really is, rather than just solving them blindly. Thank you so much for that! Final in 2 days.

[wirechair]

thanks, i love multiple interpretations..helps to build a stronger understanding

[daldous]

Definitely agree on this.

Especially for tricky concepts like this -- the more ways you can explain an idea (particularly visually), the easier it is to grasp.

[surfmimibg]

you are better than the mit lecture i watcher!! and not because i don't understand stuff. Good job!!

[Sweetpealov]

im glad dat im checking the video out now, before i start my calc class in d spring

[Potatofreak33]

This guy is good.

[Ade161]

no shit

[twebb72]

sorry, didnt watch the whole video before I commented. he gets to it...

[twebb72]

its easier to explain it as rise over run. (then you don't really need to memorize it, cause it just makes sense)

[Willdavis4]

Where was this guy when I was taking precalc to calc 4

[leocmen]

Sir, I just have to thank you.

One of the best concise explanation about Derivative I saw so far.

[Adhemar05]

much love to you, after 5 years (of bad teachers) I finally understand this xD

[drexil14]

regardless of the skill of the teacher i think that after 5 years of doing problems and looking through a book you would have learned it, i think that you either didnt learn from something as simple as this or you never tried before when you had a chance

[Blueknightex]

I should've discovered this video earlier..if I have I wouldn't be so down on my

Senior Year on Calculus =(

[Skone117]

really ez to do, just use the formula or the power rule to get the derivitive of a function.

[pik4lif]

awesome.. can you fly?

[bull912000]

Made perfect since at the end of the video. Thanks man.

[moniquebabby]

i wish he was my high school calculus teacher

[kaidestinyz]

This guy is the most amazing Maths teacher I've seen in my life. Never have I once understood what the hell Differentiate was all about despite countless explaination from different teacher until just watching this video. Awesome.

[Soboredwtf]

Thank you so much for putting this up. I really need help with calc for my engineering course and my instructor is from russia... there are alot of wariables and walues and nuclear wessles. I don't understand what he says. But I'm happy I found this.

[437thx1138]

The best explanation I've seen yet. Good job.

[TlogicoP]

Wow... using the internet like this brings tears to my eyes. Wonderful, just wonderful.

[popedarren]

@TlogicoP Weird isn't it? Maybe not too many people watch it because Justin Bieber doesn't make a pop-rap cameo about his no *limit* love for derivatives, but there are actually things one can learn on the internet. Gotta love it.

[supertren]

@TlogicoP I agree!!, this is an excellent way to use internet!. Thank you Math TV for this videos!.

[SeargentSmash]

i cant stop staring at his teeth i dont know why they hold some power over me

[poopyscoopy5]

hah

[rosevilleparkway]

I wish I had this guy as a calculus professor, mine isn't even half this good!

[wingegia]

the limit part was easy to understand, the graph was great. but... cant seem to understand what that have to do with velocity and the other word example.

[Intimidatorx31]

uhhh if you really want to know.. i can explain it to you. just private msg me.

[darijo203]

That slope is the rate of change (speed in this example) at that very point on the curve.

When you have non linear s/t graph...you cannot determinate exact speed in some point of the time since the speed changes constantly (acceleration). You must have two points on the curve to determinate the slope(speed) at some point in time, but that is impossible since there are infinitive number of points coming towards that point in time. Limit describes that (h->0). And that very limit is the slope.

[darijo203]

...sounds confusing....but that is the whole point of derivatives. In fact, if I'm not mistaken, derivatives were "created" because of that speed problem.

If I move from point A to point B during some time, what was my speed at time X? Not average speed, but the exact speed at that particular time.

Confusing at first, but once you get it the rest of calculus will be "easy".

[djsygma]

keep it simple, good!

[Rain4Life2009]

What? this is confusing -_-

[lolokoperro]

you brain isnt good enough ?

[Rain4Life2009]

This is .......AWESOME I love math

[jrendoso]

there is not sound !!!! wear.

[naszonice]

YOU ARE THE BEST!!!!

[MISTERIOUSKURL]

hey thanx soo much it was easier 2 understand

<3Lyne

[occeo]

I like how relaxed the teaching is.

[damelatuya]

muy viril...

[Pharatos666]

can u do calculs 3 "Divergence Theorem" i am so lost there thanks

[69erthx1138]

Are you doing specific problems of just trying to understand the theorem?

[SuzumiyaHaruhi0]

AYA HIRANO

[maycruz31]

this video is very helpful. how can I download this video.

[hekoloaka]

search in google for

"google downloader"

and download it

it's a free software, it does not contain any virus or spyware or so and it will help you download all the videos you want form youtube and othere similar servers.

to download it and watch it in "quicktime player" when downloading select "HQ15"

and thats it

[lolokoperro]

who asked ??????????

[joan4ril]

very helpful wxplanations!!! can you help with graphing derivatives using the function???

[maycruz31]

how can I download those derivative video?

[oabrahamsson]

I'm refreshing my school math so I can study more advanced stuff on my own later (just for fun!). And I must say I have never EVER heard a better explanation of derivatives. This is a great vid. Thank you!

[KarensBathtub]

You're a genius!!!

Thanks for great explanations!

[angyujian]

Thanks dude! This really helps for selfstudy... Hope my math teacher can be this good when I finally get to do it in school

[asphyxiateDrake00]

This math teacher would make an incredible bass or baritone; his voice is so sonorous--and wonderfully so!

[Roel12345678]

this is waaaaaaaaay too long ago for me :S

[ReadPsalms1]

uhhh, I think I walked into the wrong class...(lol)

[lastplacewin]

The highlight of this video.

[nshuvo]

If you understand culculus , you are nothing but a genius because you really have to like and be good in math. I kinda like trigs. so far.

[smithsansoo]

The best explination of a derivative I have ever seen, expecially the visual explination. Thank you.  I believe with this approach to math, we could all be math literate.

[fred25o]

This is very good thank u!!!

[IRFraggy]

THERE IS NO SOUND IN THIS VIDEO.

[trevenman]

There is, but it is enabled only for your left speaker, so balance your speaker output.

:o)

[ThunderAppeal]

Stupid youtube, I was going to pause this video and accidently rated it 1 star.

This is a five star video!

[indierockdays]

thank you ¡¡¡

[CHINMAYACADEMY]

VERY NICE!!!! more maths videos are available from CHINMAYACADEMY

[Kinghercules]

Hey does anyone have the program Derive?

I cant get my sin and cos values to come out correct. Im getting wrong answers.

[mechwarreir2]

Finally! Someone who can explain the derivative with ease!!! 50000/5 if possible!!!

[DrIntrebec]

50000/5=10000

[Janskleig]

Wow i didn't understand after 10 sec of this video o_O

[misteratoz]

is that a joke? It's not good.

[misteratoz]

I like this video and I don't know how you got the impression that I didn't. My previous comment was directed at Janskleig who acted like a jackass. Why would I be here if I didn't like his lectures People can't read these days.

[browneyedgrl299]

seriously, i'm a math major failing because the professors here suck. you've really helped me understand what my teacher clearly cannot.

[wormsleeches]

no shit girl, ours suck too and this guy actually takes a breath and explains it in NORMAL english... you rock old man!!!!!!!

[rishont2]

Sir, I just wanted to say, that your teaching methods are amazing, and that you've helped me a lot! I'd like to buy one of your books, and I'd appreciate it if you'd tell me what is the title of the book.

Thanks a lot, and please keep posting videos!

[stootypal]

GOOOOOOOd

[pa6xylly]

you, sir, are fantastic.

[senantiasa]

I want to send him money

[sokkakings]

May God Bless you.

[senantiasa]

Darwin plagiarized!!

[evilh0ly]

damn, i hope you teach at my school.

[rajeshjnvjas]

It is so nice for students.

[nuevitas25]

He is the profesor I need

[kristinmarie987]

Geez, why couldn't my calculus teacher explain it that way...

Super helpful, thanks

[1a1a2a3a]

lmfao

[centereddude]

aww, he's so sweet and calm. I bet most people access this video when their super-stressed and Mr. Cool here makes it all okay. Thank you!

[DrgnKiyo]

I love you. Seriously. I may not drop Calculus II now. On that subject, is there a Calc II in 20 minutes? ^^;;;

[rryking]

me too

[jacobbis4lovers]

I had to to go through calculus 2. It's hard!

[luvzoya]

thank you for your videos.. can you please make a few videos on hyperbolic functions
