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
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
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.
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!!
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
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.
from anhui university... this lecture is really helpful during this rapand corona wave...................................................................................................
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.
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?
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?
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
Already in the first 25 seconds you could teach me something that my teacher was unable to. Thank you.

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
This guy is my hero 👌🏽
Edna Kirkland same dude!!
All of us!
True
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
Same here from Ethiopia
By far the best video out there: quick, simple, straight-to-the-point. It helped me greatly! Thank you!
Man, God bless you. You are doing really good thing!
Teaching is the biggest charity...

Usually videos don't help me much but this one did holy fuck. This man is a god
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:
@@erubohinaus me some hours before exam
I love you so much. You are my Calculus tutor. Thank you for all your help
started watching this since my finals for basic calculus is tomorrow
"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.
Im no longer even going to watch my teachers videos im coming directly to your videos.
i thought it was difficult but he makes it simple
Thank you this was very helpful and well explained.
Great work man. I wish I'd be able to attend a class of yours someday
I literally was suffering from this. thanks
This video was actually really helpful
you are always the biggest help when studying for exams

you are goated and taking me through an entire unit. thank you
Great video! Thank you so much for making it. You're awesome.
can you do a video revealing your face
Omg😂😂😂💀
HAHAHAHAH, but I'm good with this one

from anhui university... this lecture is really helpful during this rapand corona wave...................................................................................................
This guy teaches better than my professor, my professor should get fired
i learned more in 14 minutes than in my hour and 20 minute class.
learned how to do in literally 2 min of video, thx
vro thank you so much you lterally save me from mental breakdowns
Sir, you literally saved my life
You explained it better than the teachers at the university
Super amizing good because of your vlog tutorial I got some knowledge from you
when he's doing your exact problem
You're a hero
Wait, this is so much easier than I thought
you are a great teacher sir
I got same question in my online test. Thanks.
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!!
It's like you know my syllabus
lmaoo
You are genius!!!
You are an angel!
Thank you for clear explaination :)
It's really a good explanation
i love ur method sirrrr love u alot
he is awesome!! 😍
I think I’m ready for tomorrow’s quiz now
Thank you sir😭
@4:43 We find out this guy is human :-) In all seriousness, your videos are super helpful. Thanks!!
Nice sir I can understand
f(×)=ײ-2×+1/×-2 find local extreme value and interval of monotoncity
really helpfull
Thank you! very helpful.
i love you
the second example is literally the hw question I was stuck on lmao
hocam tesekurler sayenizde calculus alla oldum
thank you my king
You are AMAZING
Great video but what about trig fnc's?
We pay thousands of dollars to a university to finally learn from youtube.
At the same time i am learning math and my ears are resting
I LOVE YOU!
Thanks!

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?
thank you
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?
If x=0, then f(x) =x³ will be ?
i love you man
How would we write our answers if the given function is rational with asymptotes in its graph?
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.
i have a question why did 6x^2 gcf is 6 while 12x^3 gcf is 12 with a variable x
Thank you man. Really.
Thank you!
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
The multiplicity stuff is confusing
Thanks a lot
very helpful
thanks a lot❤️
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?
Allah bless you & your family.
Is there a sample problem for maxima and minima for area?
So fucking clear than my professor teach!!
Please reveal ur face...so that i could give you a super big hug if we ever meet by a chance💛
Thank u sir
What about trigonometric functions?
Nice video
Thx you so much
Thanku sir ✨🙂
MY HERO
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
who came here for there modules thats damn hard
What is a derivative
tnx
muy bueno friend
On 4:00 how do you find the derivative of that number 2X^3
3*2x^2=6x^2
The power goes down then do a [ - 1] from the power so it will be (2) so it will be 3 × 2×*2 then it will be 6×*2
Good
Thnx sir
thanks :)
2:41 a happy winky face
Now I can't concentrate
