Cheat sheet I made. I think this covers everything. Concavity can be ignored if you just use the previous graph you sketched to find the next derivative: DIFFERENTIATING A GRAPH Slope ==> y-Value SHORTCUTS: Increasing ==> Positive y-Value Decreasing ==> Negative y-Value Max/Min ==> Zero Inflect.Pt. ==> Min/Max INTEGRATING A GRAPH y-Value ==> Slope SHORTCUTS: Positive y-Value ==> Increasing Negative y-Value ==> Decreasing Zero ==> Max/Min Min/Max ==> Inflect.Pt.
Not a math student but heard lectures for basic physics graph....thank u ...really understood why acceleration is positive if x-t graph is a parabola up...thank u so much
Doing this in college, this tought me if 4 minutes what i failed to comprehend in 10 days. This shows that so much about learning as a student depends on a teachers ability to actually teach.
There is a Turkish proverb for thankful: "Sana ne kadar teşekkür etsem azdır" which means " I don't know how much thanks can be enough for my thankful." 🙏🏻
I just want to say thank you so much. This video helped me more than anything I've been trying for the last week. You really saved me here. Thank you so much!
bro im learning maths in german but this helped me more than listening to some explanations in german even tho I didn't know what concavity meant in german but i just understood it bcz how good that dude explains thank you so much ❤❤❤
2 tertiary units could not exemplify what you just did. There is no point in giving a whole bunch of derivative functions without understanding their graphical connection. Thank you!
Not clear if x max of functon f(x) as x >>+3 or x >>-3. On other on right x close to 2 is max as well. What is solution to find max or min point of function.
I simply don't get it. I don't know how it's so obvious where the line is. So f(x) has a negative slope, and f'(x) is negative in that spot. Ok? That's still only half the battle. Whether there is a point of intersection or inflection helps, but it still doesn't work for the problem I'm applying this to. What happens when there is an inflection point that isn't a local min/maximum? What if the entire graph is positive? In this case, I definitely can't have the line go below the x axis because the whole slope is positive, but that means I can't cross the x axis at the inflection points? Do I still have f'(x) touch the x-axis at the inflection points of f(x)? What is the line doing between the inflection points, aside from being positive?
the process taken to draw the first derivative is used to find the second as well. (the 2nd derivative is the derivative of the first derivative). So you're drawing the derivative of the 1st derivative. (hope this helps😉 )
谢谢！
You are very welcome! Thank you for the support 😍
HOW DID YOU EXPLAIN THIS IN FOUR MINUTES BUT I STRUGGLED TO UDNERSTAND IT FOR WEEKS :OO UR CRAZY!!!
Samee....I was mad behind this concept
Thanks
It's just about grabbing the basics, as long as you do that, you should be good.
SAME!!!
dude explained this in 4 mins what mine couldn't teach in almost a week
mama
It took me a semester and still wasn't able to understand but this guy explained it in 4 minutes!!!
why cant this guy be my calc teacher
It'd make it too easy
This video is amazing, I've been so confused with curve sketching for 1st and 2nd derivative, but this video helped me understand it. Thank you!
Cheat sheet I made. I think this covers everything. Concavity can be ignored if you just use the previous graph you sketched to find the next derivative:
DIFFERENTIATING A GRAPH
Slope ==> y-Value
SHORTCUTS:
Increasing ==> Positive y-Value
Decreasing ==> Negative y-Value
Max/Min ==> Zero
Inflect.Pt. ==> Min/Max
INTEGRATING A GRAPH
y-Value ==> Slope
SHORTCUTS:
Positive y-Value ==> Increasing
Negative y-Value ==> Decreasing
Zero ==> Max/Min
Min/Max ==> Inflect.Pt.
Thank you so much. In 4 minutes you've taught me more than my math teacher has in the past week
Please be my professor you explain everything so well. Literally just saved me.

wowww this helped me so much on my math project. Thank you!!

I love Turkish language ❤
This was, scarily well explained
I just want to say thank you so much. This video helped me more than anything I've been trying for the last week. You really saved me here. Thank you so much!
Thank you yet again!!
Been watching these whike working out and theyve really helped expand my understanding. Cheers!
Got my exam in 30 minutes and this just made sense. Thank you ♥️
This is the guy all my tuition money should be going to.
Makes so much sense now🎉 spent like 6 hours confused
i love this man
This helped me so much; thank you!!
I hope you live a long life and get whatever you wish for
saved me for my exam today, thank you!!!
Did you pass the exam?

u just saved my life
Thank you! Amazing teaching!
Ohh, I see! Thank you! My calculus teacher’s accent is nearly impossible to understand.
you are a legend good sir holy moly guacamole
Bro explained this in like 5 min while my calc teacher didn’t elven mention it before putting it on our test
i love you so much, king. i have my unit 5 ap calc test today and i have 0 confidence.
Can you be my calc Professor? mines just told the class to read the book or look for a tutor
Wow😤
Surely the f'(x) gradient at 1:20 is positive judging by his red line drawn????
Thank you! Hope this could help me!!! One day before HSC
Man this is amazing. I coded my trading bot using these lessons. Thank you so much!!
brilliant explanation
Amazing video man
Thank you.

Yooo this helped me. Thank you 🙏🏾
Let's clarify this a little bit. Finding zeros of f prime is the extrema of f graph, also the zeros of f double prime is the extrema of f prime 😎🤓
Why are the ratings disabled? This video is really helpful!
thanks!
Absolutely!
I just don’t get it….. I hated this topic in calculus
@@Algebrainiac me too
Thank you❤️
Not clear if x max of functon f(x) as x >>+3 or x >>-3. On other on right x close to 2 is max as well. What is solution to find max or min point of function.
well explained thank you.
Thank youuuu I love calculus bc of you Mr. Brian handsome
thank uuu
you are a genius
Thank you!
Well explained
Thanks.
omg he helped so much, thank u

bruh this was good
omg i finally get this
0:49 No, f'(x), you just said "f(x)".
From 2 to 3, shouldn't the second derivative go downwards?
3 was a constant so the point was 0

I'm still kind of confused of where the second derivative came from, could someone explain?
the process taken to draw the first derivative is used to find the second as well. (the 2nd derivative is the derivative of the first derivative). So you're drawing the derivative of the 1st derivative. (hope this helps😉 )
