Isn't it fun when you try and undrestand/explain something in your own words but your math teacher says your wrong so you find a video to explain it and all the video does is say what you said.
This is why I really hate those stupid books, I'm doing Alan Weinstein Calculus 1 and its terrible written, making something so simple that you can learn in 5 min, as if it was some complicated hieroglyphics. Thank you Sal for making this world a better place.
The intervals where this graph is increasing or decreasing would be totally different if this was the graph of F ' (x). Let's just keep that in mind. Sal did a great explanation on the graph of F (x).
Yup thought the same too, my teacher said the intervals are basically when the function starts going up/down so notations would be (-infinity, half way between a and b), (half way between a and b, half way between b and c), and (c, infinity)
wonderful presentation sir.But wouldnt be point B the point of inflexion if the graph line had been more steeper through point B . I mean we can regard that point as straight line.Nor the line curves upward or curves downward at that point. - via YTPak(.com)

I love the episodes where he uses 4 different colours on the same page. It just sparks a joy in my heart that I cannot explain.

Nice
My teacher is like, you’ll ONLY follow how I did. Other methods are wrong and you’ll get 0
I support the teacher

Indeed, videos are superior and more efficient ways of absorbing knowledge, there is no comparison.
I would be ahead of my class if I understood this :,)
do you understand it now that it is three years later
Vibe check probably not😅
@@vibecheck4588 yes. I'm in calculus now
Vibe check lmao
@@vibecheck4588 it's 4 years now 😩
OMG! I finally got the right video !! Your way of explanation is far better than any other tutors! Thank you!
my teacher is terrible at teaching so I better get used to looking for lessons online:’)

khan acadamey always explains things soo much harder
not rlly tbh. well i guess sometimes...but u do get this one right? i mean, in this video, he explained it very well :)
Omg I have a test on this tmmr and I was confused all class thanks for helping me understand
F'(x) or F(x) we need to choose for looking sign (+ve or -ve) ? Please answer me
This is better than how my algebra teacher taught me thank you very much! ❤😅😊
These videos are great. refreshers for finals!
TYSM! I was really confused by what it was asking by when the graph is Positive and Negative on my assignment.
THANK YOU KHAN ACADEMY I HAVE A TEST TODAY AND I DIDNT UNDERSTAND ANYTHING MY TEACHER SAID THANK YOU SO MUCH 🙏😅
using different colours and doing it along with you helped so much
Why did I learn this better with khan academy than my math teacher
I think the positive interval f(x) was going to be ab,I don't know my thought is correct or not
Yup thought the same too, my teacher said the intervals are basically when the function starts going up/down so notations would be (-infinity, half way between a and b), (half way between a and b, half way between b and c), and (c, infinity)
i fw u heavy vro
Thumbs up
explains very well
thnx 😄😄
Very helpful, thanks!
Thanks!!
Great video!!
thanks sal :) 💞🤙🏽🌬
Bro no way I came on an algebra I video when I’m tryna learn for ap pre calculus 😭😭👍
Thanksss!
only need 45 seconds to understand something my teacher has been trying to explain for weeks lmaooo
wait I still don't understand why it is not less than or equal to. can someone please explain?
How do people not understand this?
erm..some ppl may not b as smart as ya mate :')
You’re one of those people in class that complains an A -
how to make video like this? using what app?
I don't get it

I DONT UNDERSTAND I HAVE HOMEWORK ABOUT THIS AND IMA FAIL. HELPP MEEE
ok
did u fail after all
@@floriographyy no
I got a test on this today....my grade is about to drop
least favorite part of my algebra class so far
wonderful presentation sir.But wouldnt be point B the point of inflexion if the graph line had been more steeper through point B . I mean we can regard that point as straight line.Nor the line curves upward or curves downward at that point.

when khan academy is your subsitute teacher the whole semester so your teacher can coach and you don't understand khan at all
