Great video, I learned from another video the concavity and came for the inflection point, but I reinforced my understanding of concavity while watching your video. 2 birds on one shot :) thanks!
+joshua kusuma yes. I'm sure I have at least one video on my channel of a function with more than one inflection point, if you wanted to see an example.
This was great help. This new webassign system hacc is using is completely pointless. Apparently I'm supposed to learn calculus from reading the book...
maybe a question. Why do we derive twice! We do not equate the first derivative with zero, as in Rolle's theorem.!! Why do we derive twice and not 3 or 4 times?

Hi great video, but one question: I understand here you are told there is a point of inflection so you can use f''(x) =0 to find this point. But if you just had that equation and were asked to prove it was in fact a point of inflection at x=2, how would you go about it? I'm aware that a point of inflection implies that f"(x)=0 but I also know that f"(x)=0 does not imply that it is necessarily a point of inflection.
Thanks. You'd do literally exactly the same thing. Although we knew ahead of time in this case that there was a point of inflection, we didn't know where or what it was and when we looked for it we didn't use the fact that we knew it exists. If you're just told to investigate then you do all of the same steps. The only difference is it's possible to conclude that there are no inflection points.
Sorry, missed the notification on this one somehow. I don't think so. I don't see how using the third derivative can be helpful when looking for points of inflection. For points of inflection you want to know where the second derivative is positive, negative, and zero. The third derivative basically only tells you when the second derivative is increasing, decreasing, or constant.
Critical numbers are values of x where f'(x) = 0 or where f'(x) is undefined, but f(x) in this video is a polynomial and polynomials are never undefined.
+surya krish Points of inflection can only occur in two places: (1) Where the second derivative is zero, or (2) where the second derivative is undefined. The second derivative is never undefined in this example because it's a polynomial. And there is only one point where the second derivative is zero (x = 2). So in this case it is not possible that there are two or more inflection points.
This helped me more in 12 minutes, than my professor could in an hour and 15 minutes, Thank you!
LOL
I love worthless professors (: my favorite
took my professor 3 hours and this helped more.

short, simple and to the point, precisely what's needed 👏
i rarely comment on videos, but I just need to tell you how great you are, thank you so much!
You saved me, may god reward you the best in your life
I was slightly confused in my class, but this video helped clear it up. Thanks!
I'm very impressed, I'm sure i will do great in my exams .All thanks to you.
you rock man. Spent a week at outdoor ed as a cabin leader and came back with a test as a welcome back gift. this helped
hope your test went well 5yrs ago

Thank you very much! This is much more helpful than other videos I've watched or examples I've looked at.
One of the most useful content in youtube
This video lecture really helped me 100 times in a couple hours than my lecturer who took more than 3 hours teaching me
Big up
Very easy to understand. You made this feel like it was some basic algebra problem!
Nice, from not understanding to fully understanding in 10 minutes :D

Your teaching procedure is so good. You clear my all points thank u soo much Sir!
Thank you so much... Because of you i undesrtand my module😊
You're speaking knowledge my friend!
Thanks sir ,good explanation
Thank you, thank you, thank you! You saved the day! :)
you're amazing, thanks so much
Thanks so much! I feel a lot better about my quiz tomorrow!
thank you for the in-depth explanation!
Thank u!! Ur video helped a lot😊... Love from India 🇮🇳 ❤️
Thank you so much this really helped me a lot 🙏
thank you sir KEEP UP THAT FRUITFUL WORK
This vedio very nice because my understand concavity up and dawn tank you very much
Very impressive lecture
Great explained, great worked
Wow , everything was easily understood, so thankyou
Thanks alot,,, today I learned something new🌺🌺
Thank you this really helped me 😩💜💜💜💜
very good teaching.
Yeah, all the thank-yous, but why did he stop uploading?
From Bangladesh, I am interested in PoI though it's the topic of advance classes. Thanks for helping me to make it clear.
You're awesome. Keep it up.
I'm literally learning this 1 hour befour the exam and i hope it work , good video!
How was your exam
@@pagalinsaan8231 haha bad i think I'll get 9 points out of 20 thanks for asking tho
I'll study earlier next time lol
@@Dhia_anims i had also maths exam hopefully i will get 15 out of 20
@@pagalinsaan8231 i hope so
kudas sir....well expalined..cheers..!!!!!
Tq so much sir.. Really this video is very help full..
great videos, very helpful
I want concavity for the points X= -1/2 ??
thankyou it's very helpful to me
Thank you so much sir . you've really helped me with this please make more videos on this topic.
thank you thank you thank you
You helped me as much as I can not write because I am hindi medium student not able to understand english much but you gave subtitles so ❤❤❤❤❤❤❤❤❤❤❤❤❤💞💓👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍
Thanks sir I am from Pakistan
I understand very well
You a blessing fr!!!
very well explained. thank you

Is it possible to have two different x values which would lead to two different points of inflection?
+joshua kusuma yes. I'm sure I have at least one video on my channel of a function with more than one inflection point, if you wanted to see an example.
Thanks Sir, that was pretty awesome
there are more than a 100 "so" in this video. however, it's really helpful. thanks
Thank you brother!
Thank you for your help
Was very helpful! Thanks!!!
8:02 ...and beyond!
I'll show myself out...
Thanks for your help!
Thank you so. Just what I needed to know
No problem, glad to help.

Oh ok, I understand it now thanks! Also is it worth using f'''(x) instead of doing this method for a point of inflection?

Thanks, does ciritical number is only for f'(x)=0?
Critical numbers are values of x where f'(x) = 0 or where f'(x) is undefined, but f(x) in this video is a polynomial and polynomials are never undefined.
excellent sir
Leaving a comment for myself: 9:00
amazing !
When we find the y-coordinate , why we don't plug the x=2 into the F" instead of the F ???
Quyen Nguyen because we want the y-coordinate on the graph of f. We can't get that from f".
Very good
how can you write intervals including infinity? there could be two or more inflation points where the function's sign could change.
+surya krish Points of inflection can only occur in two places: (1) Where the second derivative is zero, or (2) where the second derivative is undefined. The second derivative is never undefined in this example because it's a polynomial. And there is only one point where the second derivative is zero (x = 2). So in this case it is not possible that there are two or more inflection points.
Thnx a lot
Excellent
Thanks
thank you soooooooooooooo much
are you wearing the camera on your head?
Why are we using the second derivative and not the 1st, to find the graphs concavity?
Jean Claude because the second derivative is what tells us about concavity. The first derivative doesn't.
thnx a lot please
Thank you brah
u rock thank you
nice vid man
