Inflection points introduction | AP Calculus AB | Khan Academy

Lol thank you so much right when i needed help in inflection point 1 minute later you upload it.

This is not completely related to the topics you are lately showcasing, but, could you at some point turn in the future to explaining discrete math elements? Sets and relations and stuff. You have a couple of videos about relations and functions, but these topics can be sort of convoluted. Also, mathematical proofs. I'm having a lot of problems with those.

cool

I think I learned that the inflection point is where the second derivative is 0. I suppose if the second derivative is always 0, then that isn't true.

does that aply for sin and cos functions ??? because the f ' (sin) isn't a cos!?!?!?

He forgets to mention that inflection points also happen where f'(x) and f''(x) are undefined.

This helped a lot. THANKS!!!!

Find number of inflection point for the graph f(x)= x^2, for x>=0
f(x)=-x^2 for x<= 0 ?

Awesome job boss. I love the Khan Academy videos. Thank you.

Thanks 🙏🙇

Helpful! Thank you!

Increasing & Decreasing and Concave up & down are two different concepts...... But this video mixes them together.

Thanks a lot

Alright, but in the third example, the functions graph represent a straight line. There is no concavity in that.
I just don’t get where the inflection point came from .

bet u cant draw 2 concave downwards together😂😂
