This is absurdly well produced. Good camera quality for the time, great commentary, good shots and camera work in general. Good audio , even being able to hear the audience and contestants well. Legit, professional sports broadcasts can take note from this.
If you really wanna learn about calculus, then there are plenty of good calculus videos in RUclips. Believe me what they are doing, you can too! you just need to learn about them and then keep on practising :)

Must be so cool to arrive into the MIT community as a bright (maybe socially isolated) ~18 year old. Suddenly you're among others who can discuss mathematics and play around with algorithms together for fun.
So i just finished learning integration at my school today and I thought it was pretty easy and fun to do. I forgot about this video when I watched it years ago because I had no clue what this type of maths was. Now the video came to my feed, and I just realised my integration knowledge doesn't even scratch the surface of what there is.
Back in the day you could come for a professor's job by posing problems to them and seeing if they could figure them out. So this would be a great, and traditional, way of figuring out which math prof gets tenure this year
2:37:04 this one is tricky and has a trap (which Vijay fell for). So the idea is to decompose it to "simple fraction", so you get 1/x(e^x+1) - 1/x(e^3x + 1) Then intuitively, you'd want to separate into 2 integrals (which Vijay did and he got 0 as answer), but you can't do that because you'd get 2 divergent integrals (because 1/x is not integrable at 0) In order to separate into 2 integrals, you first need to do integration by parts (integrate 1/x and differentiate the rest) so that you get ln(x) which is integrable at 0, and then you can split into 2 integrals. From there, you do a variable change t=3x to the integral with e^3x+1, and everything simplifies nicely.
another way of solving it, which might be overkill (feymann trick), is to replace 3 by t, then differentiate the integral with respect to t. Then by the dominated convergence theorem, you can just differentiate the integrand with respect to t (interchanging differentiation and intergral), then after some simplification you get int{ e^tx / (e^tx + 1)} which gives 1/2t which is the derivative of log(t)/2 This means the integral (when you replace 3 with t) is log(t)/2 + C, but C=0 when you plug t=1. So the integral is exactly log(t)/2. Set t=3 you get log(3)/2.
for the first extreme integral (answer at 2:12:27), the answer is easily found if you use euler identity for sin(x). You simply get left with a constant term -ln(2), as the ln(e^i*x - e^-i*x) has very nice symmetry
I was actually super excited because I got this quite quickly: Instead of using complex analysis you can do what the one commentator said and do 2I = log(sin(x)) + log(cos(x)) = log(sin(x)(cos(x)) = log(1/2(sin(2x))) = log(1/2) + log(sin(2x)) then you can evaluate the integral of log(1/2) from 0 to pi/2 and get pi/2(log(1/2)) and then you can do a u = 2x sub on the log(sin(2x)) integral and you'll eventually get that integral into 1/2(2I) = I This leaves you with 2I = pi/2(log(1/2) + I so I = pi/2(log(1/2))
Normal person: "So, have you ever appeared shirtless cheering for something?" Those guys in the crowd: "Yes" Normal person: "What for?" Those guys in the crowd: "Um... well... an Integration Bee..." Normal person: ???
Whether the shirtless students are normal is irrelevant. The significant point here is that these guys are being used as clickbait. Nerds have become sexy - is that great or what.
The pressure must have been crazy, some silly mistakes from the first two contestants, but under normal conditions you can tell they’d do some of these with no problem
this is sooooo great! i was surprised that guy had trouble with integrating tan^2(x), since you can just equate to sec^2(x)-1 and remember that the derivative of tan(x) is sec^2(x). then again, probably not so easy in front of the crowd!!

Man, I remember thinking that I would never understand this when I watched this video many years ago. A few days ago, I successfully crammed everything (including integration) from Calculus 1 material for a day straight for the final and ended up getting an A for the class. Never give up, everyone.
+Hushe Absolute bullshit. Even a non-Ivy college student would disagree with that. That kind of mindset you have is encouraging you to give up and quit trying. You're ridiculous.
@@hushe3302 Honsetly, it is discouraging to others, but being in only pre-ap geometry, and seeing others understand these new concepts within seconds and be able to apply it with the understanding that takes usually days to get made me realize this. hard work cant beat the talent people have in these classes, exactly why tests are not the same types of problems than what you learn, they different problems that you can only solve if you have a great understanding of the subject.

There's something cathartic about watching MIT students make simple math errors
So i just finished learning integration at my school today and I thought it was pretty easy and fun to do. I forgot about this video when I watched it years ago because I had no clue what this type of maths was. Now the video came to my feed, and I just realised my integration knowledge doesn't even scratch the surface of what there is.
It would be fun to see the faculty version of this. Special functions, grassmann variables, path integrals...
Haha, yeah... I know, right? They would totally do those things you said, as we all know.
Back in the day you could come for a professor's job by posing problems to them and seeing if they could figure them out. So this would be a great, and traditional, way of figuring out which math prof gets tenure this year
2:37:04 this one is tricky and has a trap (which Vijay fell for).
So the idea is to decompose it to "simple fraction", so you get 1/x(e^x+1) - 1/x(e^3x + 1)
Then intuitively, you'd want to separate into 2 integrals (which Vijay did and he got 0 as answer), but you can't do that because you'd get 2 divergent integrals (because 1/x is not integrable at 0)
In order to separate into 2 integrals, you first need to do integration by parts (integrate 1/x and differentiate the rest) so that you get ln(x) which is integrable at 0, and then you can split into 2 integrals.
From there, you do a variable change t=3x to the integral with e^3x+1, and everything simplifies nicely.
another way of solving it, which might be overkill (feymann trick), is to replace 3 by t, then differentiate the integral with respect to t.
Then by the dominated convergence theorem, you can just differentiate the integrand with respect to t (interchanging differentiation and intergral), then after some simplification you get int{ e^tx / (e^tx + 1)} which gives 1/2t which is the derivative of log(t)/2
This means the integral (when you replace 3 with t) is log(t)/2 + C, but C=0 when you plug t=1. So the integral is exactly log(t)/2.
Set t=3 you get log(3)/2.
The commentators really saved the thing. At least someone had to know how to integrate
for the first extreme integral (answer at 2:12:27), the answer is easily found if you use euler identity for sin(x). You simply get left with a constant term -ln(2), as the ln(e^i*x - e^-i*x) has very nice symmetry
Yes, I ran this in Mathematica, which arrived at - (Pi * Log[2]) / 2
I was actually super excited because I got this quite quickly:
Instead of using complex analysis you can do what the one commentator said and do 2I = log(sin(x)) + log(cos(x)) = log(sin(x)(cos(x)) = log(1/2(sin(2x))) = log(1/2) + log(sin(2x))
then you can evaluate the integral of log(1/2) from 0 to pi/2 and get pi/2(log(1/2)) and then you can do a u = 2x sub on the log(sin(2x)) integral and you'll eventually get that integral into 1/2(2I) = I
This leaves you with 2I = pi/2(log(1/2) + I so I = pi/2(log(1/2))
@@angusclark6170yeah same
tbh the insights the commentator was giving were actually pretty good throughout
As a mathematician myself, I enjoyed this video and frankly speaking, I learned some stuff from it as well...
Normal person: "So, have you ever appeared shirtless cheering for something?"
Those guys in the crowd: "Yes"
Normal person: "What for?"
Those guys in the crowd: "Um... well... an Integration Bee..."
Normal person: ???
stupid joke
Sumner Evans 😂😂
Whether the shirtless students are normal is irrelevant. The significant point here is that these guys are being used as clickbait. Nerds have become sexy - is that great or what.
I'm that normal person
@@zanti4132 nerds were sexy in 2006 when everyone was watching tbbt
Me watching this intently for the first 30 minutes wondering when the “interrogation” starts.: 🧐🧐🧐
Commentator has to be some kind of a PHD student
Really knows his stuff while still being more entertaining than a professor
"high definition" is an understatement considering this was 2006
“ i think everyone wants to see a right answer at this point “ - savage
I would have left my career at that comment !
The pressure must have been crazy, some silly mistakes from the first two contestants, but under normal conditions you can tell they’d do some of these with no problem

@UCJ2DFPYDjLvkcSvoMhN_YlQ I bet 1000 bucks they are 10 times more successful than you will ever be you absolute loser
@Macy sondheim yet here you are watching a 3 hour long video from 5 years ago of kids doing math in your free time
@Macy sondheim someone just posted you i just came to witness this historical event
@Macy sondheim ngl you sound like a simp bro
Lol he got ratioed
this is sooooo great! i was surprised that guy had trouble with integrating tan^2(x), since you can just equate to sec^2(x)-1 and remember that the derivative of tan(x) is sec^2(x). then again, probably not so easy in front of the crowd!!
Yeah it is bitch
they are probably just not that good at maths.
@@mathematics5573 this isn't real math lmao.
Real math is logical like philosophy
Being good at fast integration has no correlation on you're ability to do math
@@revl6151 Rubbish,
@@mathematics5573 Then you haven't taken higher level math courses. Topology, abstract algebra, complex analysis, etc
This is real math, you're ability to do fast integration, simple calculus has no impact on you're ability to do real math. Often the people who were slower at calc do better at higher level math
it’s literally 3 AM and i woke up to this what?
could u pls explain is there some culture of sleeping with watching yt content or something as there are lots and lots of comments like this??
@@dyhsehehb6232 hm? im kinda lost sorry but i’ll answer to what i understand
i personally like sleeping while watching anything tbh, but i dont think it’d s culture or anything lol also most of the time i get sleepy but im too lazy to yk close youtube and put my device away so i just sleep by it some times also accidentally
moral of the story is that people are jusy lazy, too sleepy or just like to sleep by it! it could be comforting tbh buttttt not the best to do so
lmao this is so nerdy. i kinda like it
No u
@@madhavsankaranarayanan4588 Nuh uhhhh
@ki kus Doing integrals for fun is pretty nerdy and weird. they never said it was a bad thing.
@ki kus I think your finding a problem with the word nerdy and weird. Weird is just meaning its not normal and no shit people who go to MIT are not normal and nerdy is referring to someone who does complex things for fun or likes very complex things for fun so I think your problem is that you think there being used as a derogatory terms.Other then that I don't know what fucking tangent you are on.
@ki kus nerd doesn't mean you're smart. It means you are socially inept and weird, because you only do one thing in your life.
As a Mathematic Grad student, I am very jealous of those guys' talent, good job. Wish I could be as smart as them. Watching this whole thing while doing my research really boost me up. Thank you, cheer! =)
Indian high school students writing the entrance for the IITs are way more intelligent than them.
Dude you’re math grad students you’ve solved integrals so much harder than this one and honestly math 505 has some good integrals to look into
Some of these were soo easy 👍
@@DeadPool-nx3gyGood for you my guy
Me staring at these integrals blankly, “wow common they couldn’t get 4 integrals in a row”
So RUclips recommends me this after not being able to solve an integral by partial fractions feels bad man
This is world class commentary. The integration was ridiculously impressive, and i probably couldn't do a lot of those integrals, let alone in under 5 minutes, but i could NEVER commentate like that, bravo commentators

sorry, no idea what round anything was in.
I did videos on my channel for most of these if anyone is interested. :)
Man, I remember thinking that I would never understand this when I watched this video many years ago. A few days ago, I successfully crammed everything (including integration) from Calculus 1 material for a day straight for the final and ended up getting an A for the class. Never give up, everyone.
Thank you for your inspirational words Egg.

Probably math professors or Wall Street quants.

+Hushe Absolute bullshit. Even a non-Ivy college student would disagree with that.
That kind of mindset you have is encouraging you to give up and quit trying. You're ridiculous.
@@hushe3302 Honsetly, it is discouraging to others, but being in only pre-ap geometry, and seeing others understand these new concepts within seconds and be able to apply it with the understanding that takes usually days to get made me realize this. hard work cant beat the talent people have in these classes, exactly why tests are not the same types of problems than what you learn, they different problems that you can only solve if you have a great understanding of the subject.

I fell asleep to a "Debunking Flat Earthers" video and woke up realizing I had watched 3 videos on calculus, and 4 MIT lectures on physics and now this while I slept. Now I can move objects just by looking at them.
I'm about to graduate college with an economics degree and I haven't touched an integral since 2015. This is awesome content! Even the first round was fun to watch - much credit to the commentary booth.
