Love that how he smiles while catching his breath every single time he rubs the whiteboard, also little jokes here and there just to make sure we don't doze off........he took the time to write out ALL steps+explanations, i can relate to the sigh of relief after each full sheet of derivatives is completed because i have been following him throughout this period with drinks by my side. The fact that he only takes a 3 MINUTE break in between this madness shows his commitment to help us. Excellently-executed session with everything covered about basic derivatives all while maintaining a positive mindset(though we can feel his internal pain and mentally-drained energy as well as the gigantic muscle cramp of his left arm). Moments like intentionally solving them the wrong way gives us a better understanding on the dos and donts of derivatives. Feels really satisfying after this session because i don't need to worry about STPM calculus for the most part ( that is until i am greeted by the "other" family right after this). (Will definitely come back for 100 integrals and differential equations later on). Keep up the good work because you teach SOOOOO WELL, looking forward to your future videos. Remember! Your efforts are NOT unnoticed.
Encountered this video while studying for my calculus exam. I already had my exam 4 days ago and never in my life would I think at 2 am, bored, looking for a thing to do, I'd say "Maybe I'll go back to the 100 derivatives video and do some derivatives". Honestly, you made this fun and a very rewarding learning experience. I couldn't believe and still can't that you would actually do this in ONE video! Thank you so much for doing this. This really helped me hammer in the needed practice, understanding and usage of derivative rules. I only wish I found this video earlier so I could have had such a strong basis of derivatives from the get-go :O I will definitely be watching more videos and learning from them.
As a teacher you already have so much to do and then you also run a YouTune channel and post videos regurlarly? YET YOU STILL HAVE THE ENERGY TO MAKE THESE VIDEOS? I don't think I have seen a such dedicated and hard working person EVER! I have the biggest respect for you... Simply legendary.. You are breathtaking!

i believe there is a mistake on problem 42, it says x squared minus x squared minus one. when you cancel the terms it should have been minus one instead of one.
Mate never get demotivated ..... Never think what u have done now is useless ...... It has helped my whole class .... Keep smiling start blessed ... Have a good day
There was 0 shot I watched this whole video but I appreciate you. This was a very honest and sincere thank you at the beginning of the video and I think you seem like a very good teacher. This is what the world and education especially needs, and that's more people like you.
Wow! Before I was in Calc I thought you were doing some crazy challenge, but this is actually a super helpful study tool. Thanks man! I look forward to using your integral video for practice.
I recently bought a book called " Pocket Book of Integrals and Mathematical Formulas" by Tallarida and it contains an insane amount of reference information. For some reason I'm fascinated by the idea of familiarizing myself with every equation in the book and writing them out. To my point, you have absolutely motivated me while I continue my journey to get my BS in Mathematics. Thank you!
I have to say that this is the best channel to learn math on the whole internet. I came across a lot of youtube videos about math, but not a single person explained it as well as you do. The effort you put in is crazy. 6+ hours of just derivatives.. for us! I am amazed. Also. This video is also very funny. I like the moment at 1:05:30, how after finishing your sentence you just put down your pen and stare into the camera. Very comedic. You are truly a gift for us students! Keep it up!
I love how passionate he gets, he really is enjoying this. I hope I too can find something I can be this passionate about to do for the rest of my life
Hi I'm from Brazil, I'm studying in Brazil, thanks for the wonderful marathon of derivatives, it's been a while since I studied this subject, the way you presented it was perfect, and I don't understand English, except for some basic words, so that's the way you explained it, it was so that anyone who wants to learn can understand even if they don't know english, congratulations.
Because watching this video is your choice whereas you're forced to do your homework and you know that homework is going to be an absolute waste of time.
This is soooooo soooo helpful. I honestly didn't know you did this. I studied alone without any help last week for my Calculus 1 exam. This would've helped me so much. Still I'm gonna solve every problem you put, to exercise my brain. Nice video dude, cheers! And thank you for helping us out with this hard videos, you're a hero!!
your enthusiasm and dedication to your Upward Bound students are so wholesome, teachers like you remind me of my appreciation for all of the selfless teachers out there and that there is still good in the world
Omg!! This video really helped me a lot. I'm a Calculus 1 student and am working on improving my differentiating skills with you. I watched almost all of your 100 everything. Now I only have 100 integrals and 100 series left to watch. I really respect and appreciate your hardwork, Mr. blackpenredpen. You're my hero. If I was your student, I would feel really proud and lucky to have you as my teacher. Your dedication is admirable.
I've had this video in my watch later playlist for like a year and a half, finally got to solving though. Thank you very much for making this, I'm definetly doing the other 100-everything challenges! For problem 28, I tried taking natural log first, and this is what I got: dy/dx = (y^3 + xy - y^2) / (2y^3 + xy^2 + x^2)
He probably can’t do it all in one sitting. I would imagine it would take at least twice as long as this video since most Differential Equations tend to be pretty long.
I can't sit at one place for even few minutes...but you 7hrs ..420min..25200sec...kind appreciation for your hardwork by showing pure smile on your face ...I got enough clarity on this chapter..👏
Hey man, I really hope you see this. I've never seen your videos before and I don't know why you did this, but I really appreciate you for doing it. I mean 6. HOURS. standing between a whiteboard and a camera and having your arms and body at weird angles is ridiculous, but you were smiling and energetic to the very end. You have some amazing character by that alone. Like I said, I don't even know what the purpose of this was. So thank you for your effort, much respect!
This video really helped me passed calculus 1. Thank you bprp. I've discovered my potential that practice by repetition is key to passing. And now I'm in calculus 2 so wish me luck.
You are not only a good motivator for math learners but also a good motivator for physical fitness!! Salute for your skill and fitness.... I am teaching differentiation to my son from your videos. !!!Salute!!!
I watched this video before this semester of taking calculus to refresh my memory because i was taking it after a long break and I could not do any of them and now after almost finishing my semester I can easily do all of them so I think that I grew a lot. Hopefully I will understand the integrals much better after next semester of calculus 2
You are amazing! Our doctor at Engineering Portsaid University recommended your video to us and gave us your questions as homework. Thank you for your effort ♥
Awesome! I just started learning about derivitaves in my calculus class, and what I'm looking at seems frightening, but I will definitely be back to this video once I'll be at this level. Amazing effort. Easy sub.
Before watching this video, I knew basically nothing about derivatives. 6 and a half hours later and they feel super natural and easy. Thanks for the video, it was super helpful, clear, and informative!
Reading in class 12 from India I did almost 200+ derivatives in last 2 days 😎 around 12+ hours of course we don't have the hyperbolic derivatives but we have everything else here i learned new methods of differentiation thanks for your effort blackpenredpen I love your videos ❤️ I will also go through the 100 integral video once i complete my existing ones ❤️❤️
The nice thing about problem 13 is that I know the derivative is automatically sec^3x without doing any work, given that I’ve integrated sec^3x so many to remember that 1/2 secx tanx + 1/2 ln |secx + tanx| + c is the *anti-derivative* (integral) of sec^3x. Therefore, sec^3x is the *derivative* of 1/2 secx tanx + 1/2 ln |secx + tanx| + c.
He is the type of teacher that will continue discussing and giving seat works even after the class bell already rang just because it's the last period.
I have no idea what compelled you to do derivative problems for nearly 7 hours but its super helpful for people like me who learn through a lot of examples!
Question 19- could also be done by Let g(x)=x^x take ln on both side ln(g(x))=xlnx. Differentiate it. d(ln g(x))/dx . d(g(x))/dx=lnx +1 1/g(x).d(g(x))/dx= lnx+1 d(g(x))/dx= (lnx+1)(g(x) d(g(x))/dx=(lnx+1)(x^x)
Professor Chow, you are awesome. Thank you for posting these videos and take pride in that fact that you are doing good for the world. BTW, I love how carefully you erase the board.
This helped me so much! thank youuuuuuuu!!!!!! please, pleaseeeeeee do the 100 differential equation video!! i need it so much right now and you basically are the only tutor that i can understand well!
This is amazing. Thank you for doing this video!! I’m studying to prepare for my Calc. I class in the spring and your explanations are very clear and easy to follow. I’m so grateful for this video
This was incredibly beneficial for students. (I taught AP calculus for 32 years.) I would suggest doing the last few problems first (where you're proving product rule and quotient rule.) That would validate to the students that what they did for the first 96 or so problems was legitimate, (in other words they KNOW that the steps they were performing were correct because they've seen the proof for why they work!) Great job as usual.
Haven't brushed up on basic calculus in 4 or 5 years and I'm about to head back to school for math. This video really helped me resolidify my differentiation skills. Thank you and I am a big fan!
problem 95 d/dx(sin(x) you use lim h->0 sin(h)/h . My prof went on and on about this is important , but never said why . Now I know a reason . Thank you .
So we not gonna talk about the fact that this man held up that mic in his left hand for over 6 and a half hours? That’s an endurance workout right there
i always have a tough time taking notes because teachers always block the board when writing and i hate that so much , and i really love the fact that u don't so this is my favorite thing about this video . Also the way u teach is very understandable because english i my second language and i finally understand everything in a lesson .You are the best teacher i've had in my entire school life , thank you so much .☺☺

Encountered this video while studying for my calculus exam. I already had my exam 4 days ago and never in my life would I think at 2 am, bored, looking for a thing to do, I'd say "Maybe I'll go back to the 100 derivatives video and do some derivatives". Honestly, you made this fun and a very rewarding learning experience. I couldn't believe and still can't that you would actually do this in ONE video! Thank you so much for doing this. This really helped me hammer in the needed practice, understanding and usage of derivative rules. I only wish I found this video earlier so I could have had such a strong basis of derivatives from the get-go :O
I will definitely be watching more videos and learning from them.
i can do 100 derivatives much faster
my function of choice is e^x
😂😂😂
lol
Will you be differentiating with respect to y or z? ;p
@@piotrabunski5885 with respect to e
Which is e^x!😂😂😂
As a teacher you already have so much to do and then you also run a YouTune channel and post videos regurlarly?
YET YOU STILL HAVE THE ENERGY TO MAKE THESE VIDEOS?
I don't think I have seen a such dedicated and hard working person EVER!
I have the biggest respect for you...
Simply legendary..
You are breathtaking!
Thank you!!!!
I am on my summer vacay now and will try to do as many this kind of videos as possible to benefit future students! Thank you!

i believe there is a mistake on problem 42, it says x squared minus x squared minus one. when you cancel the terms it should have been minus one instead of one.

I recently bought a book called " Pocket Book of Integrals and Mathematical Formulas" by Tallarida and it contains an insane amount of reference information. For some reason I'm fascinated by the idea of familiarizing myself with every equation in the book and writing them out. To my point, you have absolutely motivated me while I continue my journey to get my BS in Mathematics. Thank you!
Imagine doing a 100 series video and begin the video saying: "yes, I am series"
😆 you read my mind. I have that video already plus I said exactly that in the beginning
Next video : 100 Partial derivatives
「Steve28」혜성 GG hhahah
I want 100limits
Of one 100-variable function
YES
I want trigonometry
I have to say that this is the best channel to learn math on the whole internet. I came across a lot of youtube videos about math, but not a single person explained it as well as you do. The effort you put in is crazy. 6+ hours of just derivatives.. for us! I am amazed.
Also. This video is also very funny. I like the moment at 1:05:30, how after finishing your sentence you just put down your pen and stare into the camera. Very comedic. You are truly a gift for us students! Keep it up!
Thank you!
I thought he was going to find the 100th order derivative of one function...
Actually that would be painful and awesome at the same time
Next video, Finding the Order of 100th Order derivative of one function... function is e^x.....
Imagine the formula you would need lmao
e^x(sinx+cosx +x^2)
Do it forever. Good luck
That would go to zero very quickly for many functions
I love how passionate he gets, he really is enjoying this. I hope I too can find something I can be this passionate about to do for the rest of my life
Hi I'm from Brazil, I'm studying in Brazil, thanks for the wonderful marathon of derivatives, it's been a while since I studied this subject, the way you presented it was perfect, and I don't understand English, except for some basic words, so that's the way you explained it, it was so that anyone who wants to learn can understand even if they don't know english, congratulations.
Why do I prefer watching these then doing my actual math homework?
Because watching this video is your choice whereas you're forced to do your homework and you know that homework is going to be an absolute waste of time.
Because you're watching, not solving.
Lucas shut up you simp ☺️
Because you're not doing anything.
Stop procrastinating like the rest of us you lazy ass
This is soooooo soooo helpful. I honestly didn't know you did this. I studied alone without any help last week for my Calculus 1 exam. This would've helped me so much. Still I'm gonna solve every problem you put, to exercise my brain. Nice video dude, cheers! And thank you for helping us out with this hard videos, you're a hero!!
thank you very much. I am very glad to hear it. : )
Dude?? If you learn even a single word from him he's your teacher....
Re-learning all of this as an adult. By far the most helpful videos for me. Thank you for doing this -- I really appreciate it.
your enthusiasm and dedication to your Upward Bound students are so wholesome, teachers like you remind me of my appreciation for all of the selfless teachers out there and that there is still good in the world
Omg!! This video really helped me a lot. I'm a Calculus 1 student and am working on improving my differentiating skills with you. I watched almost all of your 100 everything. Now I only have 100 integrals and 100 series left to watch. I really respect and appreciate your hardwork, Mr. blackpenredpen. You're my hero. If I was your student, I would feel really proud and lucky to have you as my teacher. Your dedication is admirable.
Man, I studied the heck out of this video. This was truly excellent! Teacher quality 10/10.
I just did derivatives for like 5 hours today and now I see your video and you do them IN ONE TAKE. wow amazing
Are you kidding me?! Again?! You are so ambitious!
😄😄😄
I've had this video in my watch later playlist for like a year and a half, finally got to solving though. Thank you very much for making this, I'm definetly doing the other 100-everything challenges!
For problem 28, I tried taking natural log first, and this is what I got: dy/dx = (y^3 + xy - y^2) / (2y^3 + xy^2 + x^2)
Great to hear!
Q 34 can further be more simplified at 2:36:08 as { [cosx + cos^2(x) + sin^2(x) + sin^2(x) ] / ( 1 + cosx )^3 }
to simply 1 / (1 + cosx)^2.
Next: 100 Differential equations! Great work
He'll do it for sure :-) :-)
I'd love that ODEssey
Yes yes yes
He probably can’t do it all in one sitting. I would imagine it would take at least twice as long as this video since most Differential Equations tend to be pretty long.

Hey man, I really hope you see this. I've never seen your videos before and I don't know why you did this, but I really appreciate you for doing it. I mean 6. HOURS. standing between a whiteboard and a camera and having your arms and body at weird angles is ridiculous, but you were smiling and energetic to the very end. You have some amazing character by that alone. Like I said, I don't even know what the purpose of this was. So thank you for your effort, much respect!
Who Else Skipped 6 hours just to see the clock moves .

This is really epic
This video really helped me passed calculus 1. Thank you bprp. I've discovered my potential that practice by repetition is key to passing. And now I'm in calculus 2 so wish me luck.
You are not only a good motivator for math learners but also a good motivator for physical fitness!! Salute for your skill and fitness.... I am teaching differentiation to my son from your videos. !!!Salute!!!
I watched this video before this semester of taking calculus to refresh my memory because i was taking it after a long break and I could not do any of them and now after almost finishing my semester I can easily do all of them so I think that I grew a lot. Hopefully I will understand the integrals much better after next semester of calculus 2
the first 20 minutes of this video helped explain the chain rule easier than weeks of my professor trying.
Respect for these types of videos bro,still watching it even tho i don’t understand anything
it's derivatives, nothing really difficult here, I think this is by far one of his easiest video

almost had a heart attack
I just wanted to say that this is so helpful! Also, you're the only teacher that can make me smile and motivated while doing math. Thank you so much!
What you were saying was quite tough for me understand, but everything is pretty much clear, thanks for this great video.
Reading in class 12 from India I did almost 200+ derivatives in last 2 days 😎 around 12+ hours of course we don't have the hyperbolic derivatives but we have everything else here i learned new methods of differentiation thanks for your effort blackpenredpen I love your videos ❤️ I will also go through the 100 integral video once i complete my existing ones ❤️❤️
The nice thing about problem 13 is that I know the derivative is automatically sec^3x without doing any work, given that I’ve integrated sec^3x so many to remember that 1/2 secx tanx + 1/2 ln |secx + tanx| + c is the *anti-derivative* (integral) of sec^3x. Therefore, sec^3x is the *derivative* of 1/2 secx tanx + 1/2 ln |secx + tanx| + c.
That's just your problem, "knowing" the answer is not the same as finding it in the reverse direction.
Best math teacher ever! You really helped me in my study, thank you BlackPenRedPen!
At first I thought you're gonna differentiate the same thing 100 times hahaha.
Διονύσης Χριστόπουλος maybe I will do that one day too
me too haha
@@blackpenredpen but it repeats after the 4th term
He is the type of teacher that will continue discussing and giving seat works even after the class bell already rang just because it's the last period.
I have no idea what compelled you to do derivative problems for nearly 7 hours but its super helpful for people like me who learn through a lot of examples!

thumbs up if u agree.

I have a partial exam on derivatives on Thursday. This couldn't have come out at a better time.
Nice. Challenge for you, what is the pattern to the answers?
Question 19- could also be done by
Let g(x)=x^x take ln on both side
ln(g(x))=xlnx.
Differentiate it.
d(ln g(x))/dx . d(g(x))/dx=lnx +1
1/g(x).d(g(x))/dx= lnx+1
d(g(x))/dx= (lnx+1)(g(x)
d(g(x))/dx=(lnx+1)(x^x)
Professor Chow, you are awesome. Thank you for posting these videos and take pride in that fact that you are doing good for the world. BTW, I love how carefully you erase the board.

You forgot to put 6x^2 for number 8 when finding the derivative of 2x^3. You almost gave me a heart attack.

This was incredibly beneficial for students. (I taught AP calculus for 32 years.) I would suggest doing the last few problems first (where you're proving product rule and quotient rule.) That would validate to the students that what they did for the first 96 or so problems was legitimate, (in other words they KNOW that the steps they were performing were correct because they've seen the proof for why they work!) Great job as usual.
Just finished the video... I tried them all as I watched! Thanks BPRP you're making me a better teacher!
