Studying for an exam tomorrow and reviewing notes... My notes make no sense whatsoever in the way I wrote them.. I just want to say THANK YOU for your help. Good luck on your quizzes/exams to the others watching this video!
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.
+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.
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 ❤❤❤❤❤❤❤❤❤❤❤❤❤💞💓👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍
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.
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...
+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.
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!
@@American_patriot110 no, I wrote this comment just 24 hrs ago, i was watching this video while doing my homework and saw your name and i didn't think you were going to reply but you did wow!
@@Leadwithlove654 lol 😆 my bad, i wanted to say "i wrote" instead i put U in the place of i. Thanks Huuno, Glad you are studying Hard. Keep going forward sis
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 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

I was slightly confused in my class, but this video helped clear it up. Thanks!
You saved me, may god reward you the best in your life
Thank you very much! This is much more helpful than other videos I've watched or examples I've looked at.

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
One of the most useful content in youtube
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
Thanks sir ,good explanation
Thank you so much... Because of you i undesrtand my module😊
Yeah, all the thank-yous, but why did he stop uploading?
Your teaching procedure is so good. You clear my all points thank u soo much Sir!
Thank u!! Ur video helped a lot😊... Love from India 🇮🇳 ❤️
This vedio very nice because my understand concavity up and dawn tank you very much
you're amazing, thanks so much
Thank you, thank you, thank you! You saved the day! :)
From Bangladesh, I am interested in PoI though it's the topic of advance classes. Thanks for helping me to make it clear.

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?

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.
Oh ok, I understand it now thanks! Also is it worth using f'''(x) instead of doing this method for a point of inflection?
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.
I want concavity for the points X= -1/2 ??
Thank you so much this really helped me a lot 🙏
Great explained, great worked
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.
thank you for the in-depth explanation!

How was your exam

I'll study earlier next time lol

Thanks alot,,, today I learned something new🌺🌺

Thanks, does ciritical number is only for f'(x)=0?

Thank you this really helped me 😩💜💜💜💜
thank you sir KEEP UP THAT FRUITFUL WORK
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".
Thank you so much sir . you've really helped me with this please make more videos on this topic.
Awesome 👏🏻
thank you thank you thank you
Thanks sir I am from Pakistan
I understand very well
Thank you sir thank you so much
great videos, very helpful
thank u king!
Thank you!
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.
Thank you ❤
are you wearing the camera on your head?
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.
