2.71 million subs aren't enough...I passed both AP and honors chemistry, Algebra 1,2 and 3 enhanced, and AP calculus just by watching your videos. Not to mention, I also show the Investment Club I lead your investment and stock videos as well. Thank you so much, God Bless.
Just wanted to say thank you, you are a serious life savor. I usually use your videos as a brush up on what we learned in class, bc I suck at math, and now with online classes and the whole pandemic, I have found myself even more confused and I feel lucky that I knew where to turn too (bc our school has bad tutors too). Thank you so much for your videos!
You are the best teacher - best on TH-cam. I learn a lot from all your videos. Thank you so much. Please post more AP Calculus and AP Chemistry videos. Please post AP Calculus videos with solved college board questions. Thank you.
I got full mark in the exam...I do not even practice my Textbook queries as once I watch your video everything is explained well..your are extremely good in explanation..pliz update more and more videos..
I really like all your videos. They are the best on youtube, in my opinion. But my attention span litterally ends in like 6 mins or so when I watch ur videos.. like, I struggle to stay focused. 😁. But anyways, awesome vids! Keep it up! 😎
For the last problem I dont think you would include -3/2^1/2 because it is equal to -2.1 which is outside the restricted domain. so there would be no local min and -2 would be the absolute min. Correct me if Im wrong.
52:10 If you want to shave (valuable) seconds off (while getting a better idea visually/kinestheticly), don't bother wasting time "testing points" to find out where the derivative changes sign. Simply quickly plot the (*numerator of the) derivative, ie plot f' vs x. Just use end behavior and the zeros to do this. (*Yes, there is something in the denominator in this particular example because we are dealing with a rational function, but in this example the denominator is always positive, so it won't affect finding where f' changes sign. Keep in mind, that you can avoid "testing the points" 100% of the time if dealing with a polynomial function.)
@36.12 it should be minus 12(0) i.e -0 and not +0 as stated in the question but more importantly perhaps @ 3.27 which should be -12(2) and not +12(2) ...... -24 and not +24 hence final answer @36.45 should be -7 and not +41.
Very nice but on 7:20 you said if f'(c) doesn't exist, we have a cusp. Not necessarily coz we might have vertical tangent just like in f(x)=x^(1/3) at x=0 . So how can we tell if we have a cusp or vertical tangent?
its a cusp because if f'(c) doesnt exist at x=a certain number then its not differentiable at that number and not differentiable means the first derivative isn't continuous on x=that number. Its only a verticle tangent if f(x) is undefined, not f'(c)
question on the laast problem..................................why would you include -3/2^1/2 ???? its already beyond -2???? please answer??organic chem plssss
14:08 you said if the leading coefficient has a odd power like x^3 then it will have no max or minimums. but at 22:21 that function also has a leading coefficient with odd power of ^3 but that one has a max and minimum for some reason?
First of all, your videos are grades saving. But this is not what I want to say cause it is obvious, my question is how the hell do you know all those things like physics, chemistry, and math😅. You make me feel like they are piece of cake
When you plug in a 2 into 2(2x-3), wouldn't you get a negative 2 instead by following order of operations, so instead of 2X2 = 4 -3 = 1, you'd do 2 - 3 = -1 X 2 = -2?
I have a query. at 3:58 we have a graph which does not have a minima as last point is encircled and therefore is not part of the graph but the point before that is included in the graph so why we don't consider it as a minima. Thanks in advance
Hi, for the first problem you did, does it matter which number you plug into the first derivative? You did plugged in a # that is smaller than 1.5 into 2(2x-3). If I plug in a # that is smaller that 1.5 into 6x-6, would I still get the same answer as you? Thank you!
made a bit of petty mistakes compared to other tutorial films but so what! It's an absolute fact that he is very helpful to most of the Math degenerates out there
the only thing i dont like on your video is the volume inequality. you speak soft, so i turn the vol up. whenever the ads comes, it wakes everyone up since i study at night. :(

I hope a math formula invented in the future is named after this guy to instill his helpfulness for all of time.
Thank you for helping me to pass high school and univeristy. You're a life saver, thank you.
Much Love from Africa,you are really helpful sir.
I wish people could donate; this guy is very calm and helpful.
This guy's videos helped tons of people!

you're the only reason I'm passing calc thanks for your videos

In the class they don't teach us like that.. Thanks, it helped me a lot.
Just wanna say you are amazing teacher....You solved mah biggest problem....you are just outstanding...
I understand you better than my teacher, thanks so much for making this videos they have helped me a lot
When my friends asked me how do i get so good at calculus, i simply answer. “Im just an apprentice to a Calculus god on youtube”
Shut up

Cringe bro
I AM BUT THE APPRENTICE
You’re videos are excellent because you explain and cover all the materials perfectly! Thank u very much!
from the bottom of my heart, thank you so much for these videos
I really enjoyed watching your videos. Very explanatory and understandable.
SUPER CLEAR! I LOVE THIS!
please, keep up with the videos you are a life saver!
you the best teacher i have ever come across online . you are so smart
This guy is a life saver 🙏🏾

you are really a great person thank you so much for shearing your knwledge because knowledge is freedoom
I am a normal student,I see this dude's video,I like
OK. You corrected it. I was wondering why no one mentioned it earlier.
Thank you for this video, nice explanations. One correction: f(2) = 3(2)^2 - 12(2) + 5 = -7 actually, not 41. Cheers!
Whoops, just saw your in-video correction. No worries!
that is a historical moment 36:45
lol, he made a mistake!
Amazing, My calc professor is horrible at his job. You should make a video to “HOW TO TEACH A STUDENT” and I’ll share it with my professor 😂❤
For the last problem I dont think you would include -3/2^1/2 because it is equal to -2.1 which is outside the restricted domain. so there would be no local min and -2 would be the absolute min. Correct me if Im wrong.
At 1:09:00 he said it’s not part of the interval
Best teacher ever thank uuu so much

Bruh he corrected it in the video itself.
This was really helpful, Thanks a lot.
This video has saved me in my darkest hour
awesome, now do it with trig max and minimums !!
thank u
All I could say is thank you very much.
44:30
In 27:55 it's super complicated.
Thanks ❤. please do videos on area between two curves and also on volume by slicing disks and washers methods ,volume by cylindrical shells
I like your voice...
Cursseeee you, that tutor guyyyyyyyy!!!!!!!!!
these long videos are soo helpful and in depth, can you make vids on Vector Geometry and Linear Algebra !??!
Very helpful,thanks ❤
Very useful. Thank you sir.
Thank you
youre the best!
Thank you so much for everything 💕
Excellent, as always.
Thank you !
Thank you very much👌👍
thank you chief
Very helpful
Quick question: Wouldn't the square root of 9-(3)^2=0, which would create a domain issue?
Thanks G
whoever dislikes his videos will never be able to learn anything in life.
Dislikers are probably the rival educational youtubers lol
No just hate your comments
If someone commented it id probably like it
A hole
you are amazing
Great video....👍👍👍
Thanks sir big salute!
What if we have two minimums, but they are "the same"?
(-1, -1) and (1, -1). Are both absolute minimum? Or are they both local minimum?
41:33, I am confused why 0 is part of the critical points. Wouldnt it just be -1 and 1?
hey man, can you take my exam for me? thanks
36:45 he switch the -12 to +12 did anyone noticed ?
Thank You!
Thanx
Thank you so much
Seriously I Thank u.
THANK U BROTHA
God bless you
i love you
@1:04:30 you keep using -3/sqrt(2) wich is -2.12 so its out of our intervall. Or did I do something wrong here?
no youre right, i think he just made a mistake
It's been like a year but for future uses, he did remove it in the end; thus, not making it the absolute minimum value in the interval [-2,3]
Him: "and the value is 46"
Me: "OH MY GOD WHAT DID I DO WRONG HOW DID HE GET THAT"
increasin' decreasin'. My boy is such a g he doesn't have to pronounce his g's.
on 57:26, shouldn't the graph be restricted on the interval [-1,2]? Why did you make it continuous on all real numbers?
Physics C E&M Playlist?
Very nice but on 7:20 you said if f'(c) doesn't exist, we have a cusp. Not necessarily coz we might have vertical tangent just like in f(x)=x^(1/3) at x=0 . So how can we tell if we have a cusp or vertical tangent?
its a cusp because if f'(c) doesnt exist at x=a certain number then its not differentiable at that number and not differentiable means the first derivative isn't continuous on x=that number. Its only a verticle tangent if f(x) is undefined, not f'(c)
what will we do when we have modulus function
question on the laast problem..................................why would you include -3/2^1/2 ???? its already beyond -2???? please answer??organic chem plssss
Does absolute max/min mean global max/min?
14:08 you said if the leading coefficient has a odd power like x^3 then it will have no max or minimums. but at 22:21 that function also has a leading coefficient with odd power of ^3 but that one has a max and minimum for some reason?

So like... does chain rule not apply to this because when you bring the exponent down don't you have to multiply the expression by its derivative-
Thankyouuuuu🥺❤️
57:50
8:82
Shouldn't the lower local min be a critical number instead?
more knowlege in short time😱
When you plug in a 2 into 2(2x-3), wouldn't you get a negative 2 instead by following order of operations, so instead of 2X2 = 4 -3 = 1, you'd do 2 - 3 = -1 X 2 = -2?
that isnt how order of operation works....
I have a query. at 3:58 we have a graph which does not have a minima as last point is encircled and therefore is not part of the graph but the point before that is included in the graph so why we don't consider it as a minima.

Ya bro
Why don't you use the second derivative? U don't think it's faster???

Lol same
how is 5/3 present in 2/3? please explain
52:25 if you plug in 1 the answer is gonna be negative no ?
