Hello everyone coming back to review for midterms. I wish you luck on your weary travels. Edit: Also thank you for all your hard work and dedication to teach anyone willing to look up your videos. Greatly appreciated!
39:48 Y=[5+4x]^4 [7x-x^2]^5 is a product and chain rule combined but, you mistakenly said product and quotient rule hope this will clarify the misunderstanding to future people watching this. great youtube channel to learn Math and Science
Watching this 00:36 am Edit 1: this is 3 years later and i love how i still get comments from my late night chemistry homies. Also i finished chemistry at the same time this comment went up and im not looking back good luck to anyone having chem exams.
Just wanna say thank you for all of your videos! You are saving my life in calc during quarantine :) literally learn more in an hour of your videos than I do in a week of classes :0
You just explained this way better than the Princeton Review book did. The book has good practice problems I just find it hard to understand their explanations. Thank you so much 🙏
I have an indescribable desire to learn things above my grade level (as of writing im in 9th) and i cant begin to tell you how good this video is. You are very good at writing it all out so if i make an error i see exactly where it was, along with a cohesive and understandable explanation
Very Nice Video The only I want to say that at 51:55 You put 2(3) where it supposed to be 2(-3) in which will change your answer from -6+40/4 which is then equal 34/4 which is then equal to 8.5
If i had sarted from childhood with the oct videos I would be very brilliant but anyways his videos has transformed my academic life in the university. I don't know how to thank u so much oct
Something that helped me see it wasn't just a black box where you have to follow rules without understanding them was trying it with just a power of x. The derivative of x^8 is 8x^7. What if you use the product rule to find the derivative of x^5 * x^3? f'(x) is 5x^4, g'(x) is 3x^2. So you get (5x^4 * x^3) + (x^5 * 3x^2). That's 5x^7 + 3x^7, or 8x^7, the same as if you combined them.
Hi! Not sure if you will see this, but thought I would try. Thank you for these videos, they are helping me a lot. Question though: @ 37:09 you give the final answer but don't include the ^2 on [tan(5x^2+8)]. Shouldn't it be 30x[tan(5x^2+8)]^2? Is there a rule that I am missing where that shouldn't be included? Thanks!!
At 21:15, how is this derived? That is, why dy/dx = dy/du * du/dx? I understand the logic that follows but why does he reach this conclusion in the first place?
If you’re asked to find the y value for the equation of the tangent line how would you do it if you have the slope already and they give you the x value
At 57:17 why didn’t you multiply 6 with 0. Isn’t the equation like g’(f(x)) • f’(x)? So shouldn’t we multiply 6 with 0 because it’s the f(x) inside the g. And then multiply it with f’(x) so the answer would be 0 and not 42
I have a doubt, at 39:46, shouldn't the Tutor say, "The example is a combination of product rule and chain rule" instead of "The example is a combination of product rule and quotient rule". Am I missing something here?

Honestly don’t know what I would do without this RUclips channel
😂😂👋
Exactly :|
*Agreed*
Amen brother
Same here😂
i swear this guy could just do every teacher on earth's job without a sweat. He's honestly one of the biggest reasons im passing maths.
european person eh. glad to see you doing well brotha.

How can I when you belong to me but I belong to them
Erm what the sigma

yeah i wa like wtff is going on im i hearing right 😅
This content is changing the career trajectory of hundreds of thousands of people, thanks.
!
Seriously!
Watching this 00:36 am
Edit 1: this is 3 years later and i love how i still get comments from my late night chemistry homies. Also i finished chemistry at the same time this comment went up and im not looking back good luck to anyone having chem exams.
Same here 😳😳
no way what’re the chances
@@mkorkrish probably not that high
Woww many people learning derivatives in this time
1:05 am😂😂
Hi ,
At 51:55 f prime of 1 is -3 so the end result is 34/4 = 17/2 i.e. 8.5
Exactly, but he has done a great job explaining derivatives.
Thank you!
At 37:01 you forgot to carry down that the tan function was squared, so the answer should be 30xtan^2(5x^2+8)*sec^2(5x^2+8)
Yah itx squared he 4got
ya I was confused I thought I got it wrong but..
Just wanna say thank you for all of your videos! You are saving my life in calc during quarantine :) literally learn more in an hour of your videos than I do in a week of classes :0
Yea, Ikr...
Same here, this is sooo helpful
P
I couldn't agree more the way it is broken down is so amazing.
You just explained this way better than the Princeton Review book did. The book has good practice problems I just find it hard to understand their explanations. Thank you so much 🙏
Watching all of your calc videos before my 2 quizzes and test. Hopefully, I'll do well.
How did you do? =D
how'd you do gang?
Shows all the types of questions seen in AP tests great job
heard this channel from my classmates and this first video i watched is pretty informative. i now know why they all learned the lesson fast 😩
you are the teacher who every student wants thank you very much.
I have an indescribable desire to learn things above my grade level (as of writing im in 9th) and i cant begin to tell you how good this video is. You are very good at writing it all out so if i make an error i see exactly where it was, along with a cohesive and understandable explanation
im proud of u (: never let this intellectual curiosity fade-it will carry you through life
nice pfp
Same bro, even I am in 9th grade and I am learning calc to be ahead everyone!!! If I start now, I won't face much problem in the future
composite function starts from 18:13
chain rule 18:00
robintuition thanks bruh
THANKS :)
Thank you!
Thanks
Thanks for this channel, it's a great help for someone who has plan to take board exam
Very Nice Video
The only I want to say that at 51:55
You put 2(3) where it supposed to be 2(-3) in which will change your answer from -6+40/4 which is then equal 34/4 which is then equal to 8.5
I wanted to comment about this point also.
Sharp observation there. I also got it 8.5 (34/4). Nonetheless, Great kudos to the TUTOR of TUTORS!
This channel has made me a saviour to my fellow students
I can't believe I made it to the end of this video but I did. This was so helpful and I took notes on everything. The exam is next week wish me luck!
I wouldn’t even try to dream about being a doctor without this guy 😢
This guy is an absolute hero at teaching
52:01 you forget f’(1) is not 3 it is actually -3
And the answer is 34/4
The way this guy talks is nice and soothing
i really respect of you sir,you are very inteligent person you provide us knowledge with full detailed and dont miss any point
love you sir
I have my final tomorrow, thanks for clutching up for me. You my guy
This is really helpful. Thank you. Commenting just to help the algorithm.
If i had sarted from childhood with the oct videos I would be very brilliant but anyways his videos has transformed my academic life in the university. I don't know how to thank u so much oct
This guy is a legend of a Tutor❤️❤️❤️
❤️❤️❤️❤️❤️🙏❤️❤️❤️❤️❤️❤️
This Good. I thought we were gonna factorization that quadratic
I think the answer of tan³(5x²+8) should be 30xsec²(5x²+8)[tan(5x²+8)]², correct me if I'm wrong.
Thank you ( this channel) for existing.
for 37:06 , tan(5x^2 + 8 )should have square , tan^2(5x^2 +8) :D
Pls I would love u to upload hyperbolic derivatives cos u are my only reliable source of learning 😔 plsss
Thank u for all the vids they are the best help and explanations in the world👍
thank u, thank u, thank u you´ve lit saved my career , my mental stability and other stuff haha you´re the senior of calculus thanks again
thank u so much, am studying for my exams are tomorrow appreciate the teaching
Great video! Your videos are enough to understand any topic.
thanks for all your videos on calc. I literally learn more with them.
Best teacher of the worls
My differentiation skills after watching this video >>>> I can literally do mental calculations now.
You are the best, thanks for all your efforts to make a great videos. You are my favorite during my journey at College.
@51:40 you forgot a negative f'(1) is -3 not 3
im black
MCtech I’m yellow
walter clements I’m red
Richydragonball I’m Blue
@@N8_DoubleYou LOL Best one!!😂😂
37:00- you forgot the squared-exponent of tan(5x+8)
It should be... 30x[tan(5x+8)]^2[sec(5x+8)]^2
But great video though☺
Yeah I noticed that too...

That's 5x^7 + 3x^7, or 8x^7, the same as if you combined them.
How you doing buddy, sorry n0 buddy responded to you
review your video at time"37.08", a power 2 went missing at some point
i also realized that
Me too
In the final answer for the composite chain rule, it should be tan^2(5x^2+8)
You're always so gooood, but this time I think at 37:07:- you forgot to put the square above the tan(5x^2+8) in the last line.
U make my life easy thank u for helping me really
You're my savior hehe but u forgot about the negative sign on 3 (table part) It's actually supposed to be 44/4 and so the answer is 11 not 23/2
Chain Rule happens at 18:00
careful hes a hero
thank you bro
This was extremely helpful, thank you!
You’re the best
Alway!!!!
Thank you so much, you make it so easy to understand !
Great video! Shows a lot of good info.
i love you organic chemistry tutor
You are best bro
Lots of love from Pakistan ❤️❤️❤️
the desc: It also covers a few examples and practice problems on the product and quotient rule. also the vid: 1 hr of examples
at 51:54 you put 3 instead of negative 3, the answer is 34/4.
thank you teacher
Very nicely explained.
You made an error. 52:29 it was supposed to be 36/4 which then h(1)=9
Hi! Not sure if you will see this, but thought I would try. Thank you for these videos, they are helping me a lot.

Thanks!!
Yeah thats a wrong answer....
30x[tan(5x^2+8)]^2[sec(5x^2+8)]^2 is what I got...Plz correct me if I am wrong
@@rafiatbm7867 Yeah that is correct
@@rafiatbm7867 Yh that’s correct which can also be written as 30xTan^2(5x+8)Sec^2(5x+8)
This is very helpful
1 thing I notice is that in my calc class, the equations are NEVER this simple. And I can NEVER find any complex product chain rule examples online
So nice
I was really thinking about that 15:00
Thank you so much 😊
Thanks a bunch!👍👍
When your midterm is 10 questions in 75mins so you have 7.5mins to do problems that take you 30 mins each to do.
gracias :) podrias hacer analisis de funciones por favor
you're my king
At 21:15, how is this derived? That is, why dy/dx = dy/du * du/dx?
I understand the logic that follows but why does he reach this conclusion in the first place?
at 51:52 u forgot to carry the negative . it should be -3 wich makes h'(x) 36/4 wich is 9
How to form a differential equation from y=AX^2+B/x+C/X^2 where A,B,C are orbitary constant?
Watching in Master Economics 🙄!!
ahhhhh thank you so muchhhhh
good video
If you’re asked to find the y value for the equation of the tangent line how would you do it if you have the slope already and they give you the x value
Thank you. It was very informative.
big bro help me i just want to know becuase I'm confused at 35:05 why there is a 2x next to the cos when the outside is just sin
DX - D GENERATION X
thank you very much
dast xos vere good
THANK YOU
Great thanks 👍
Any econ students
👍
Could you make a video on first principles?
Excuse 37:09 power of 2
But thanks anyway learnt
The tan function should be squared tan^2 in the final answer
Watching 00:15Am
43:38 - Personal Bookmark
at 36:37 the answer is missing a ^2 on the tangent
big sis help me i just want to know becuase I'm confused at 35:05 why there is a 2x next to the cos when the outside is just sin
Thanks 👍
At 57:17 why didn’t you multiply 6 with 0. Isn’t the equation like g’(f(x)) • f’(x)? So shouldn’t we multiply 6 with 0 because it’s the f(x) inside the g. And then multiply it with f’(x) so the answer would be 0 and not 42

cheers chears.
58:46 is 2(-3) not 2(3)
f' of 1 is equal to -3
