You've got a very bad philosophy towards Calculus. One might not "learn math from a book" because you are not interested at the subject! Never insult books! They are like people. You treat them properly they reward you! Doing the opposite would make you suffer! Anyway, Keep studying Jksandilya
I understand why you're asking (curiosity), but really think for a moment - how would showing his face be beneficial to him at all? None of his videos are about him, they are about math. Also, why would it matter what his face looks like? It shouldn't matter what he looks like. To be honest, the only reason anyone would want to see him do a "face reveal" is due to curiosity. Let's be real here: that's not a good enough reason for him to do it. There just isn't a good case for it. It's pointless.
Hello you know I have spent a whole year in the university understanding the local maxima and local minima and I always fail !!!! Really I don’t know how to thank you ,I have exam after few days and you have ease my life !? You are amazing and great and the best tutor in this whole world please keep up and also post videos on statistic this channel has to get a golden reward
But in the last example, if we plug in f(2), we get y=16, so we do get a coordinate (2,16) and that could've been the relative maximum point if we used functions to do so. But theoretically we can see that it doesn't have a relative maximum point. How do we explain that with the functions method if we are asked to show our work?
I know you probably got it by now but commenting for future people, as far as I could understand it’s because it’s a double root so if you were to graph the derivative it’d look like a parabola shaping upwards. That point is a point of inflection rather than a critical point where the second derivative changes signs, changing the concavity of the function
Thank for you video! The lecture notes use many many words to explain this concept that made me confuse about it, while you use some simple examples to explain it clearly!!
The description is inaccurate: where you say "f the sign changes from - to +, it's a relative maximum." should be minimum instead of maximum; same goes for + to -, for a relative maximum.
Professor Organic Chemistry Tutor, thank you for a solid analysis and a step-by-step explanation of Finding the Relative Extrema/Max/Min Values in Calculus. This is an error free video/lecture on TH-cam TV with the Organic Chemistry Tutor.
for the f(x) 3x^4-16x^3+24x^2 I don't understand why the critical number couldn't just stay x=2 why do we have to solve for 12x=0 when we didn't in the other problems. I dont know if this is a stupid question I just think I might be over think it, can anyone help me?
He plugged 1 and -1 for the last example, wouldn't they both be positive? as -1-3 = -4 and you square that which is positive cause he did the same for 1 when he did 1-3 = -2 but he then squared it which would make it positive.
Hello how do we find maxima and minima of trigonometric functions for example what is the minima and maxima of the following function y=sin(x³/3- x²/2-2x+1) this is really enormous problem to me
13:30 how would we determine which is the shape of the curve? I'm currently thinking that it might be taking the 2nd derivative of a function and seeing how the shape of the function changes from that point. Would that be it or am I completely off?
when finding the y value, on the first one we used the f(x)' then substituted the x values......but why did we use f(x) on the second example instead of f(x)' again?
from anhui university... this lecture is really helpful during this rapand corona wave...................................................................................................
Can you do it in reverse? Have 2 local max and min (eg 4, 8 and -1,-2) I tried. x=4 x-4 x= -1 x+1 x(x-1)+4(x-1) x^2 -3x -4 3(x^2) -(3)(3x) -3(4) 3x^2 -9x -12 6x -9 6(4) -9 is minimum (which shouldn't so...) Or -x = -4 -x +4 -x = 1 -x-1 -x(-x-1)+4(-x-1) -x^2 +3x +4 -3(x^2) +9x +12 -x^3 +4.5x^2 +12x +- c -4^3 + 4.5(4)^2 + 12(4) +- c = 9 -(-1)^3 + 4.5(-1)^2 + 12(-1) +- c = -2 C = 47 C = -4.5 WHAT DID I DO WRONG?

my calc class got moved online bc of corona. this channel is literally my teacher. how did people ever learn math from a book?
Edgar Moreno same here honestly I should’ve watch this guy sooner

Anyway,
Keep studying

Math is supposed to be taught not just said out loud
Hhh our maths book is the best
I got same question in my online test. Thanks.
It's like you know my syllabus
lmaoo
thank you my king
Thank u sir
Already in the first 25 seconds you could teach me something that my teacher was unable to. Thank you.
💩
can you do a video revealing your face
Omg😂😂😂💀
HAHAHAHAH, but I'm good with this one

You explained it better than the teachers at the university
"decreasin' and increasin'"
LMAOOOOO i love how he repeats it
stop copying people's comments lmao
@@gigachad7030 wut? people can have the same reaction to something. It's not that deep. Plus it's something he says in the vid.
when he's doing your exact problem
started watching this since my finals for basic calculus is tomorrow
I could just listen to your voice all day.... it's so soothing....
HA GAYYY
he sounds like my friend off xbox so it's kinda strange but i agree

Usually videos don't help me much but this one did holy fuck. This man is a god
Great video! Thank you so much for making it. You're awesome.
Thank you this was very helpful and well explained.
i thought it was difficult but he makes it simple
I literally was suffering from this. thanks
Thank for you video! The lecture notes use many many words to explain this concept that made me confuse about it, while you use some simple examples to explain it clearly!!
I'm from Ethiopian Oromia
I see your Video teacher and it's good
Thank you I love so much and once day I see you
You are a legend u saved my life I passed an exam with less than 2 weeks preparation watching ur videos ☺️
Me the day before the exam:
Man, God bless you. You are doing really good thing!
Teaching is the biggest charity...
I love you so much. You are my Calculus tutor. Thank you for all your help
Great work man. I wish I'd be able to attend a class of yours someday
who came here for there modules thats damn hard
The multiplicity stuff is confusing
This guy teaches better than my professor, my professor should get fired
The description is inaccurate: where you say "f the sign changes from - to +, it's a relative maximum." should be minimum instead of maximum; same goes for + to -, for a relative maximum.
Thank you bc I was confused!!
By far the best video out there: quick, simple, straight-to-the-point. It helped me greatly! Thank you!
i learned more in 14 minutes than in my hour and 20 minute class.
This video was actually really helpful
@4:43 We find out this guy is human :-) In all seriousness, your videos are super helpful. Thanks!!

vro thank you so much you lterally save me from mental breakdowns
Please reveal ur face...so that i could give you a super big hug if we ever meet by a chance💛
So fucking clear than my professor teach!!
im stuck on something likes this
y=(e^(x)+e^(-x))/(2)
he is awesome!! 😍

Super amizing good because of your vlog tutorial I got some knowledge from you
you are goated and taking me through an entire unit. thank you
At the same time i am learning math and my ears are resting
f(×)=ײ-2×+1/×-2 find local extreme value and interval of monotoncity
i have a question why did 6x^2 gcf is 6 while 12x^3 gcf is 12 with a variable x
Thank you sir😭
13:30 how would we determine which is the shape of the curve?
I'm currently thinking that it might be taking the 2nd derivative of a function and seeing how the shape of the function changes from that point. Would that be it or am I completely off?
We pay thousands of dollars to a university to finally learn from youtube.
Well everyone else knows what he was saying I sure don't.
FML
i love you
If x=0, then f(x) =x³ will be ?
when finding the y value, on the first one we used the f(x)' then substituted the x values......but why did we use f(x) on the second example instead of f(x)' again?
This is the same video as the first derivative test. Pointless.
Im no longer even going to watch my teachers videos im coming directly to your videos.
the second example is literally the hw question I was stuck on lmao
Allah bless you & your family.
Great video but what about trig fnc's?
really helpfull
You're a hero
im fucking dumb as hell
from anhui university... this lecture is really helpful during this rapand corona wave...................................................................................................
learned how to do in literally 2 min of video, thx
Nice sir I can understand
thus us too much for a 14 year old brain
What is a derivative
Very informative but please get a better mic
bruh that was 5 year
2:41 a happy winky face
Now I can't concentrate
You are genius!!!
I think I’m ready for tomorrow’s quiz now
How would we write our answers if the given function is rational with asymptotes in its graph?
Sir, you literally saved my life
Can you do it in reverse? Have 2 local max and min (eg 4, 8 and -1,-2)
I tried. x=4 x-4 x= -1 x+1
x(x-1)+4(x-1)
x^2 -3x -4
3(x^2) -(3)(3x) -3(4)
3x^2 -9x -12
6x -9
6(4) -9 is minimum (which shouldn't so...)
Or
-x = -4 -x +4 -x = 1 -x-1
-x(-x-1)+4(-x-1)
-x^2 +3x +4
-3(x^2) +9x +12
-x^3 +4.5x^2 +12x +- c
-4^3 + 4.5(4)^2 + 12(4) +- c = 9
-(-1)^3 + 4.5(-1)^2 + 12(-1) +- c = -2
C = 47
C = -4.5 WHAT DID I DO WRONG?
i wish i could help u but i've no idea
Amongus
Who is watching this video in 2k20 ?
kaumay ads ni leni
you are always the biggest help when studying for exams
You are AMAZING
What about trigonometric functions?
You explained it better than the teachers at the university
i love ur method sirrrr love u alot
3ars ong
You explained it better than the teachers at the university
you are a great teacher sir
Thank you! very helpful.
Thank you man. Really.
MY HERO
It's really a good explanation
fuc i dont kwon english
go jim
Ich liebe dich
muy bueno friend
Nice video
what don't you do bruh
Good
You are amazing 💛💛💛💛💛💛
