WOW... hope this record gets acknowledged and you get an entry in the guiness book of world record. And the person Lars mentioned in the video is me, so thank you so much bprp, and thanks to all others wishing me well. I finished the first of 3 chemo rounds, and apart from about 2-3 days, I did quite well on it. If things go well with chemo, I could be free from cancer by the end of April.
Thanks to all of you. When I'm free of cancer, I will let bprp know, and he can let you all know. I have testicular cancer, and my chances of beating and surviving the next 5 years are at 95%, the highest percentage among all cancers. So I consider myself still lucky :)
@@blackpenredpen Yes, when I saw the almost 6 hour mark, it all started to make sense why you were tired, and so on. Don't worry too much about the integral. Take a break, rest a bit and be there for your students :) ... we'll be here. And even if you don't get an entry in a record book, you deserve to feel well about it, and hey, you set a benchmark for someone to challenge your 100 integrals. That's impressive :)

haha when dumb people make a relatable comment, it hurts my soul inside. One person will try to be funny and say something, showing how dumb they are and how they dont think they are better then anything, literally. Then a barrage of others will follow along. Look 4 all of you duuuuuumb bots, math is easy, i dont understand why people think its hard, its just a bunch of measurements
for question 12 I used sub x=sin(u) and the sqrt(1-x^2) on the bottom cancels nicely with the derivative of sinu, cosu to just get the intergral of usinu which is simple by parts, but your solution was also very nice.
The fact that he explained every integral with a detailed step by step rather than doing some of the steps in his head is crazy to me. Great job man, truly showing how math can be enjoyable
He didn’t explain all of them, the middle part of the video he doesn’t talk a lot, and math just ain’t enjoyable. It’s frustrating if you don’t understand something, and even when you learn it, it only feels good for the moment you learn it, then it goes back to being a pain in the ass to do
@@2kmichaeljordan438 that’s because people view math as a chore instead of having genuine interest in it, which isn’t really an issue since you can have other interests. People like the challenge of figuring out a difficult math problem and others don’t.

How could you dislike this video. This guy makes me so happy. The way he says how much he loves his gf and sends wishes to the guy battling cancer warms my heart. He is truly a magical mathematician, and a marvellous human being
Thank you. For the exercise 31 you've made -2*2=1; the response is -4*square(1-square(x)) + c. I think it's because tiredness. Anyway thank you for your work.
@@carlosmatosfanpage2856 Well you know about curves (or functions) like y = x^2 that you can plot? Well you can integrate a function like x^2 and it will make a new function, namely (1/3)x^3. Then you can use this function to calculate the area under the curve between x=a and x=b and the x-axis. It would really help to understand the differentiation process first, since this is simpler and its actually the opposite process to integration, so they are fundamentally connected via the fundamental theorem of calculus.
Can we just appreciate 1: this mans insane math skills, 2: the fact he has 2 markers in 1 hand while maintaining coherent writing, and 3: the fact he explains *every single problem* so well that my small brain can understand it.
I'm studying for a re-take of my calculus final that my professor was generous enough to provide. I'm extremely concerned because it's my last chance to get an A and I feel like this video is a great immersive way to make sure I've grounded every single method. Today is Day 2 of going through this video. I've done up to 20 questions so far. I'll be editing this comment to hold myself accountable. #5 was seriously a rough one, but even that problem was possible to solve with your step-by-step guidance. Thanks for everything, BPRP! Edit: I've made it up to 30 questions. I was really confident about #28 at first, but I had to watch the explanation several times to actually understand it. Are we just supposed to memorize when sec^3(theta) is integrated into and then replace those values by returning to the "x world"? A bit confusing, but memorization of an equation is no problem. We'll see how it goes tomorrow. (Could someone tell me HOW BPRP knew to write sin at 1:55:24 ? That means that he put "u" as cosine, right? Because the sqrt (1 - cos^2x) = sin x. But how did he decide to set "u" equal to cos and thus, get sin (or inverse sin, I guess) in his final answer? Edit: We've made it all the way to 46 questions and although I'm so close to the halfway mark, I can't bring myself to do another integral. Again, BPRP is amazing! I hadn't solved sinh(x) and cosh(x) questions in a long time so this was a really good refresher. Also, #40 was so challenging and I can't believe that someone would CREATE and SOLVE it voluntarily. I have no words. We will pass halfway tomorrow!! Edit: Today is a review day. I've made it to 50 and now, I'm going to attempt 1~25 on my own- without any help unless I really need it. #48, 49, and 50 were incredibly thorough. I don't think that we will be tested on tanh(x) or sech(x) questions, but since they're included in this video, I feel prepared. Honestly, I've only done halfway and I had a span of 5 days. It's crazy how BPRP did of this in roughly six hours. Edit: We've made it to 63. Not gonna lie, I'm getting pretty sick of integrals. I feel like 60 should be plenty of practice and I'm not exactly sure why I'm putting myself through this. We will try to push to 70 tomorrow. Yeesh. We made it to 70. I feel like giving up now would be pathetic, so I'll keep going. But I am really not enjoying this anymore. Regardless, there are some individual questions that are exciting. I remembered the double angle formula for #68 (around 4:01:00) and it was exciting to be able to solve that one on my own. Tomorrow is my parent's anniversary so I may be busy, but let's aim for 80 !! Agh, almost done Done with 80! To be honest, #72 was quite beautiful to solve, but the rest were painful. Looking forward to being done!!!! Done with 90- we'll be completely finished tomorrow. Can't wait. My stamina needs work :/ FINISHED WITH 100 !!! (Ah I forgot to update) My final is partially going to be on series + finding the radius/interval of convergence as well as integrals, so I've been practicing the 100 series video + other tutorials on RUclips. MIT OpenCourseWare has been a great tool for critical comprehension. I have a bit less than a week until my test, so during the last few days, I'll be making practice exams for myself and solving them in a timed environment. Until then, I'll keep doing 10-20 practice problems per day. (I seldom prepare this far in advance nor this thoroughly for a test, but honestly this is teaching me great learning habits! Perhaps I'll apply this to my classes during the approaching school year. ) I'll update this comment on how the actual test goes ! The retake went alright! To be completely honest, I didn't get the score I was looking for. I was looking for a 100 so it's a bit shameful to say, but I nearly fucked up again. However, I got a score that was just a few points above the good-enough standard and my grade improved, so I was able to take Linear Algebra this semester and I enjoyed it a lot. (It's way more abstract.. yet easier than Calc II to grasp in my opinion. The applications are a lot more concrete.) Thanks, BPRP :) You're one of the few people who prevent me from entirely despising math.
I ACTUALLY UNDERSTAND WHAT HES DOING :)))). I tried watching this last year prior to taking calc 1, but since i already took it, i understand now. THIS IS ACTUALLY KINDA FUN TO WATCH!
Wow, this truly cuts deep. My father was a mathematician before his passing, and he always wanted me to become a great man with a prosperous future in math. Everyday I look forward to your videos as they give me memories of my father working late at night. Thank you.
There's so many good moments in this video. He asks how I'm doing, checks up and says the video is for Lars numerous times, just what a nice guy overall. Actually watching this video over the course of a week lord help me...
For question 59 (3:14:33), I tried integration by parts and I got the same answer. It is probably slower but it's the first thing I thought of. When I did this, I got (2/3)*x^2*(x+4)^(3/2) - (8/15)*x*(x+4)^(5/2) + (16/105)*(x+4)^(7/2)+C which desmos says is the same answer. Love the vids ❤️
can’t thank you enough man you’re truly a blessing. if all math professors had this same level of dedication to teaching their students math would almost be easy. thank you for all your hard work boss we appreciate it!
At around 3:00:10 you asked how I am doing Man, it's been a rough couple of weeks. It feels like the university doesn't wanna test what I know, but instead they wanna see if they can catch me out on things I don't know well enough. It's overwhelming and difficult to stay ahead of the workload, but I'm staying positive and doing my best all the way. They'll never get me down. Thank you for asking. How are you doing?
Werner Steyn wow you are the first one who actually noticed that part!! Thank you. Yes, just like you said, stay positive. Keep putting in the effort and I wish you a successful semester!
This is the first time in 2 years that I'm actually starting to 'think' when solving integrals. Up to recently it was just a kind of 'go with the momentum' way of solving, or a painting by numbers style where I was going by purely the 'standard' way of approaching simpler integrals, which often led to walking into dead ends. Now I'm actually trying to see how to approach things thanks to watching your thought process. And it has started to work because, going into my lecture handouts I'm able to solve a lot of the integrals much more easily than before and I'm actually aware of 'why' I'm choosing a particular strategy. I know I 'rant' but I can't thank you enough for how much this is helping me. I was losing my mind and now I've started to enjoy this subject again and the magic of maths is returning.
This is honestly one of the most impressive things I’ve ever seen. And you seem like such a nice dude! I know I’m way late but congrats on pulling this off! It was amazing!
Hello. I have something important to tell you: The bible makes it clear that God is holy. This holy God holds a perfect moral standard. Sadly, we have all fallen very short of that standard(Romans 3:23). The penalty for sin/imperfection is Hell(Revelation 21:8). Thankfully the bible also says that God is rich in mercy and grace. That is why He sent His perfect Son to die on a cross to save us from our sin. You and I broke God's law, but Jesus paid our fine. Then Jesus rose from the dead, 3 days later, thus defeating death! (John 3:16-18) "He that believeth in the Son hath everlasting life; and he that believeth not the Son shall not see life, but the wrath of God abideth on him.” John 3:36 "But God commendeth His love toward us in that, while we were yet sinners, Christ died for us." Romans 5:8.
WOW... hope this record gets acknowledged and you get an entry in the guiness book of world record. And the person Lars mentioned in the video is me, so thank you so much bprp, and thanks to all others wishing me well. I finished the first of 3 chemo rounds, and apart from about 2-3 days, I did quite well on it. If things go well with chemo, I could be free from cancer by the end of April.
👍👍👍
Dude, best of luck, I hope it all works out for you.
Best wishes, man. Cancer is an asshole, so make sure you beat it!
Thanks to all of you. When I'm free of cancer, I will let bprp know, and he can let you all know. I have testicular cancer, and my chances of beating and surviving the next 5 years are at 95%, the highest percentage among all cancers. So I consider myself still lucky :)
@@blackpenredpen Yes, when I saw the almost 6 hour mark, it all started to make sense why you were tired, and so on. Don't worry too much about the integral. Take a break, rest a bit and be there for your students :) ... we'll be here. And even if you don't get an entry in a record book, you deserve to feel well about it, and hey, you set a benchmark for someone to challenge your 100 integrals. That's impressive :)

@@bananabananae not very difficult, as c can take any value each time!
haha when dumb people make a relatable comment, it hurts my soul inside. One person will try to be funny and say something, showing how dumb they are and how they dont think they are better then anything, literally. Then a barrage of others will follow along.
Look 4 all of you duuuuuumb bots, math is easy, i dont understand why people think its hard, its just a bunch of measurements
@@glilyjebamalardaviitkharag8763 caught that well...👍
Thomae function
for question 12 I used sub x=sin(u) and the sqrt(1-x^2) on the bottom cancels nicely with the derivative of sinu, cosu to just get the intergral of usinu which is simple by parts, but your solution was also very nice.
Y'all are impressed he's solving 100 integrals, I'm impressed how this man is standing for 6 hours straight
We are not the same.
im impressed how he switches his pens so fast
You hadn't seen physics wallah teachers of India who stand for 10-11 hours for lecture.
Yep! And talking, and teaching nicely, not just standing!
Thats not really impressive. Most jobs require you to stand for 8+ hours, so the majority of the adult population do this 5 days a week.
He is one phenomenal teacher. I have been recently watching his videos and he has taught me things my teachers never did. Amazing teacher.
Thank you!
Man it would be so much easier for him if he didn't need to explain while doing. Big respect
I was going to say it would be easier if he had 100 different linear functions.
But I think they are very simple calculas questions
But he spent so much time on them
@@fecesgenerator I realise it. Thank you.
It shows that he understands everything crystal clear.
The fact that he explained every integral with a detailed step by step rather than doing some of the steps in his head is crazy to me. Great job man, truly showing how math can be enjoyable
He didn’t explain all of them, the middle part of the video he doesn’t talk a lot, and math just ain’t enjoyable. It’s frustrating if you don’t understand something, and even when you learn it, it only feels good for the moment you learn it, then it goes back to being a pain in the ass to do
@@2kmichaeljordan438 that’s because people view math as a chore instead of having genuine interest in it, which isn’t really an issue since you can have other interests. People like the challenge of figuring out a difficult math problem and others don’t.
@@noxstar8140 Indeed, it depends on the person like most fields.
@@2kmichaeljordan438 no shit something will be frustrating if you dont understand it? i think you just dont have a vested interest in it.
@@2kmichaeljordan438
math is enjoyable, if u suck at it it’s not its problem, it’s yours + ofc anything u don’t understand will be frustrating not only math, and at the end of the day it depends on the person, everyone has his interest, not everyone will like and enjoy the same things
"As we all know"
no, i didnt
heartbreaking but true :v
I hate tht and when the teacher say it you fell bit stupid
Teacher: We also know... Relating to trig identities we learned ages ago.
Calc 2 student: WHAT?????
you make me laugh haha
Hello RedpenBluepen
I think answer of question number 31 is little wrong. You missed '4' in multiplication.
This is by far the best maths video here on RUclips!!! It's like a tough training session at the maths gym!!!🤩🤩🤩

this man really did 100 integrals, THEN HE DID 101. LEGENDARY

I don't know if he is a genius or a crazy man. Maybe both.
These integrals are a piece of cake for jee aspirants. They can complete these 100 integrals in less than 2 hrs

@@kushaagrgupta105 I mean they probably were easy for him too but he was explaining how to do them which is why it took so long

*Don’t even know what an integral is but this is cool*
He's basically finding a function that when differentiated will give the integrand.
Colin Java still dunno what that means xD
Colin Java you just made it more confusing; to make it simple, the integral of acceleration is velocity
@@Jason_Eissayou Yeah, that's one physical representation, not sure it helps in understand it though.
@@carlosmatosfanpage2856 Well you know about curves (or functions) like y = x^2 that you can plot?
Well you can integrate a function like x^2 and it will make a new function, namely (1/3)x^3.
Then you can use this function to calculate the area under the curve between x=a and x=b and the x-axis.
It would really help to understand the differentiation process first, since this is simpler and its actually the opposite process to integration, so they are fundamentally connected via the fundamental theorem of calculus.

Pretty cool, if I ever end up teaching something I'll use that technique
@@esquared722 It's an ancient Chinese technique.
I'm studying for a re-take of my calculus final that my professor was generous enough to provide. I'm extremely concerned because it's my last chance to get an A and I feel like this video is a great immersive way to make sure I've grounded every single method.
Today is Day 2 of going through this video. I've done up to 20 questions so far. I'll be editing this comment to hold myself accountable. #5 was seriously a rough one, but even that problem was possible to solve with your step-by-step guidance. Thanks for everything, BPRP!
Edit: I've made it up to 30 questions. I was really confident about #28 at first, but I had to watch the explanation several times to actually understand it. Are we just supposed to memorize when sec^3(theta) is integrated into and then replace those values by returning to the "x world"? A bit confusing, but memorization of an equation is no problem. We'll see how it goes tomorrow. (Could someone tell me HOW BPRP knew to write sin at 1:55:24 ? That means that he put "u" as cosine, right? Because the sqrt (1 - cos^2x) = sin x. But how did he decide to set "u" equal to cos and thus, get sin (or inverse sin, I guess) in his final answer?
Edit: We've made it all the way to 46 questions and although I'm so close to the halfway mark, I can't bring myself to do another integral. Again, BPRP is amazing! I hadn't solved sinh(x) and cosh(x) questions in a long time so this was a really good refresher. Also, #40 was so challenging and I can't believe that someone would CREATE and SOLVE it voluntarily. I have no words. We will pass halfway tomorrow!!
Edit: Today is a review day. I've made it to 50 and now, I'm going to attempt 1~25 on my own- without any help unless I really need it. #48, 49, and 50 were incredibly thorough. I don't think that we will be tested on tanh(x) or sech(x) questions, but since they're included in this video, I feel prepared. Honestly, I've only done halfway and I had a span of 5 days. It's crazy how BPRP did of this in roughly six hours.
Edit: We've made it to 63. Not gonna lie, I'm getting pretty sick of integrals. I feel like 60 should be plenty of practice and I'm not exactly sure why I'm putting myself through this. We will try to push to 70 tomorrow. Yeesh.
We made it to 70. I feel like giving up now would be pathetic, so I'll keep going. But I am really not enjoying this anymore. Regardless, there are some individual questions that are exciting. I remembered the double angle formula for #68 (around 4:01:00) and it was exciting to be able to solve that one on my own. Tomorrow is my parent's anniversary so I may be busy, but let's aim for 80 !! Agh, almost done
Done with 80! To be honest, #72 was quite beautiful to solve, but the rest were painful. Looking forward to being done!!!!
Done with 90- we'll be completely finished tomorrow. Can't wait. My stamina needs work :/
FINISHED WITH 100 !!! (Ah I forgot to update) My final is partially going to be on series + finding the radius/interval of convergence as well as integrals, so I've been practicing the 100 series video + other tutorials on RUclips. MIT OpenCourseWare has been a great tool for critical comprehension. I have a bit less than a week until my test, so during the last few days, I'll be making practice exams for myself and solving them in a timed environment. Until then, I'll keep doing 10-20 practice problems per day. (I seldom prepare this far in advance nor this thoroughly for a test, but honestly this is teaching me great learning habits! Perhaps I'll apply this to my classes during the approaching school year. )
I'll update this comment on how the actual test goes !
The retake went alright! To be completely honest, I didn't get the score I was looking for. I was looking for a 100 so it's a bit shameful to say, but I nearly fucked up again. However, I got a score that was just a few points above the good-enough standard and my grade improved, so I was able to take Linear Algebra this semester and I enjoyed it a lot. (It's way more abstract.. yet easier than Calc II to grasp in my opinion. The applications are a lot more concrete.) Thanks, BPRP :) You're one of the few people who prevent me from entirely despising math.
with your dedication I hope it passes
how did the final go?
how'd it go?

I ACTUALLY UNDERSTAND WHAT HES DOING :)))). I tried watching this last year prior to taking calc 1, but since i already took it, i understand now. THIS IS ACTUALLY KINDA FUN TO WATCH!
Glad to hear!! Thanks.
Same lol I learned about integrals a few days ago
Add me in the list :~)
i haven't done my Calc1 and i understand it because he is just too good at teaching.
I’m taking Calc 2 right now and it’s quite entertaining watching this
this was probably the first time I was smiling while doing math.... ur smile is contagious man .... loved it
Thank you!
Guess we found a new challenge for Mr. Beast
$100,000 to witch ever of his friends can do 100 integrals correctly first
BPRP is probably his friends.
He's too dumb to understand Calculus
We all know it's not gonna happen.
It's gonna happen!
Student: How to do this integral please ?
blackpenredpen: Just watch my 6 hours long video, it must be somewhere in it
LOL, yup!
He has ascended to the level of math god
Wow, this truly cuts deep. My father was a mathematician before his passing, and he always wanted me to become a great man with a prosperous future in math. Everyday I look forward to your videos as they give me memories of my father working late at night. Thank you.
Wow, this is truly inspirational. I too have lost my mathematician father to cancer. Perhaps we can link.

Even after you pull the pin you can just throw the grenade becuase after the grenade is released it has a 5 sec delay

Hello, I am a 15 year old math lover. I'm very interested in integration and your channel is really great! Thanks for your videos :D
There's so many good moments in this video. He asks how I'm doing, checks up and says the video is for Lars numerous times, just what a nice guy overall. Actually watching this video over the course of a week lord help me...
Imagine if he forgot to hit the record button
lmao true but im pretty sure he made sure he did this type of video is prolly something that he would care a lot about.
That probably hard ataq
Who said that this was his first time solving 100 integrals 🙃
Ooh u negative vibe😑
maybe he did forget and recorded the video again lmao
This is someone who truly loves what they teach, spends nearly 6 hours straight solving integrals and explaining each step for each one
*He
For question 59 (3:14:33), I tried integration by parts and I got the same answer. It is probably slower but it's the first thing I thought of. When I did this, I got (2/3)*x^2*(x+4)^(3/2) - (8/15)*x*(x+4)^(5/2) + (16/105)*(x+4)^(7/2)+C which desmos says is the same answer. Love the vids ❤️

wait, did you guys actually watch the entire 6 hours?

@@johndoesson We didn't not watch all six hours if that answers your question.
can’t thank you enough man you’re truly a blessing. if all math professors had this same level of dedication to teaching their students math would almost be easy. thank you for all your hard work boss we appreciate it!
I am very happy to hear this. Thank you!
As you go higher in mathematics, difficulty becomes inevitable, but the degree of severity can be lowered with a dedicated teacher like this fellow.
No it's not
Today i finish the whole video with you. I solve the problem by myself at first,then followed u. Thank you for being with me.
At around 3:00:10 you asked how I am doing
Man, it's been a rough couple of weeks. It feels like the university doesn't wanna test what I know, but instead they wanna see if they can catch me out on things I don't know well enough. It's overwhelming and difficult to stay ahead of the workload, but I'm staying positive and doing my best all the way. They'll never get me down. Thank you for asking.
How are you doing?
Werner Steyn wow you are the first one who actually noticed that part!! Thank you.
Yes, just like you said, stay positive. Keep putting in the effort and I wish you a successful semester!
Werner Steyn btw, I am doing well right now too. Thanks.
@John Porter that's amazing, man! Keep it up! :D
OMGGGGG, this is insane, I wish I could like this over 100 times 😍😍😍
Dr Peyam thank you!!!!!!
Ofcourse you can like it 100 times!!Sad it'll count only one...

Of course, you can like it as many times as you want. Just make sure it's an odd number ;)

I never thought I could learn so much in such little time. Gifted teacher, thanks for the dedication. Legend for explaining everything.
Glad to hear! Thank you!!

Practice this question 2 times. + 50 different questions of similar type. Then u will learn.

Normal mode, put on 1x
Hard mode: 2x
Good idea
Not really hard cus he explains everything
@Andrew Wu well I mean he still takes time to explain things so if you were to do it without talking its faster
I mean if you beat him at 2x (u really won't) why not record for the record

Should be looking at series then.
I can't believe I just watched six hours of something that I couldn't even motivate myself to do ten minutes of when I was in the class.

Max W lmao same bro
This is the first time in 2 years that I'm actually starting to 'think' when solving integrals. Up to recently it was just a kind of 'go with the momentum' way of solving, or a painting by numbers style where I was going by purely the 'standard' way of approaching simpler integrals, which often led to walking into dead ends. Now I'm actually trying to see how to approach things thanks to watching your thought process. And it has started to work because, going into my lecture handouts I'm able to solve a lot of the integrals much more easily than before and I'm actually aware of 'why' I'm choosing a particular strategy.
I know I 'rant' but I can't thank you enough for how much this is helping me. I was losing my mind and now I've started to enjoy this subject again and the magic of maths is returning.

Hello. I have something important to tell you:
The bible makes it clear that God is holy. This holy God holds a perfect moral standard. Sadly, we have all fallen very short of that standard(Romans 3:23). The penalty for sin/imperfection is Hell(Revelation 21:8).
Thankfully the bible also says that God is rich in mercy and grace. That is why He sent His perfect Son to die on a cross to save us from our sin. You and I broke God's law, but Jesus paid our fine. Then Jesus rose from the dead, 3 days later, thus defeating death! (John 3:16-18)
"He that believeth in the Son hath everlasting life; and he that believeth not the Son shall not see life, but the wrath of God abideth on him.” John 3:36 "But God commendeth His love toward us in that, while we were yet sinners, Christ died for us." Romans 5:8.
