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.
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.
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!
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.
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.
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.
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!!
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
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
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!
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 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 did do the definition of derivative from Q91 to Q100, so check out the last part of the video!
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
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.
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!
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!!!
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 ♥
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.
I would like to thank you from the bottom of my heart, I got my love for math from you. The way you explain and your enthusiasm about math when you are explaining something it always makes me happy. Thank you for the effort you put into your videos.
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!
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
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
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..👏
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)
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 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.
Thank you so much, I'm only in an hour in and things are starting to make so much sense now. I defiantly plan on watching the whole thing. And this is defiantly going to prepare me for my exam.
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!
HEEEY JUST WANNA STOP BY AND SAY THAT I PASSED MY INTEGRAL CALCULUS SUBJECT! DIFF EQ IS NEXT UP FOR ME. THANK U FOR UR VIDEOS! THEY WERE SUCH A HUGE HELP =)
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!
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 ❤️❤️
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!
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 .☺☺
Exceedingly helpful! Thank you! You are a very good teacher! Just to mention, in question 8, shouldn't the inside of function g differentiate to 6x squared?
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.
Thank you very much for your effort bprp! This video is also valuable for high school/college level. Sure I will share this with my students! Time stamp as below for those needed:

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.
Is anyone gonna talk about how he writes with two markers in the same hand and flawlessly transitions between the two?
Two years later but yes! 😁

4 years later but yup

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.
Thanks!!!
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!😂😂😂

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.
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....
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
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
Are you kidding me?! Again?! You are so ambitious!

Hi there! I appreciate the hardwork you've put in making such fantastic content for free on youtube out there. I absolutely love 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

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!
Man, I studied the heck out of this video. This was truly excellent! Teacher quality 10/10.
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 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 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.

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.
Watch it backwards to learn integrals!!
How do u watch it backwards?

Very funny

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.
@@jacobharris5894 50 would be nice too.
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.
Thanks
Thank you for your super thanks!
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!
I just did derivatives for like 5 hours today and now I see your video and you do them IN ONE TAKE. wow amazing
Thanks!
im only 5 questions in and i already LOVE your method of teaching! you make derivatives (dare i say) FUN!
Thanks! I am glad to hear it 😃
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!!!
Up to number 40, but it took me a couple of days. You are an IRON MAN. Good work, I learned (remembered) a lot going through these problems.
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!
Man the consistency of his enthusiasm throughout the video is what I want in my life.
Thanks!
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

😆 thanks!!!
I would like to thank you from the bottom of my heart, I got my love for math from you. The way you explain and your enthusiasm about math when you are explaining something it always makes me happy. Thank you for the effort you put into your videos.
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!
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
loved it!! i solved all of them (except the hyperbolic ones) really enjoyed it Great Video!! ❤❤❤❤
This man has a beautiful soul, you rock brother.
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
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..👏
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!
4:08:15 I love how he said, "yes, I'm that mature guys", without saying it.
I like your energy and passion. i did calculus nearly 30 years ago. these days tutoring school kids in math.
the first 20 minutes of this video helped explain the chain rule easier than weeks of my professor trying.
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 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.
MAn you look so happy teaching throughout the whole video, this is the motivation professors should have when teaching.
Thank you so much, I'm only in an hour in and things are starting to make so much sense now. I defiantly plan on watching the whole thing. And this is defiantly going to prepare me for my exam.
Best math teacher ever! You really helped me in my study, thank you BlackPenRedPen!
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 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?
2:36:19 34 can be further simplified.
Cos^2 x +cosx is cos x(cosx+1) and 2sin^2 x is 2(1+cosx)(1-cosx)
Not sure why but I’ve been watching and learning, ur so enthusiastic it’s contagious!! Please never change and thanks for making math fun :)

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!
Glad to hear! Best wishes to you!
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 .☺☺
Well derivatives aren't going anywhere away from my brain now. one of the best 6 hour sessions ever.
Gotta say sir, you're a really good study buddy.
Never ever in my life, i thought i would feel nostalgic watching a guy solving derivatives.

Hi, i think there is a mistake in the minute 22:30, cause the derivative of 2x3 its 6x2 and not 6x :) (i like so much your work)
i noticed that was trying to find this comment
Not sure if this helps, but he fixes it later on
best video everrrr!!!! keep going KING👑
People like him deserve all the fame and success
Exceedingly helpful! Thank you! You are a very good teacher!
Just to mention, in question 8, shouldn't the inside of function g differentiate to 6x squared?
Yes it should it was a mistake
Had the same thought.
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.
