43 minutes of monster slaying.
Am I in a dream.

I realize I'm kinda off topic but does anybody know a good place to watch new tv shows online?
i see arccos in a derivative, i moan slightly
i see arccos in an integerahl, i have a mental breakdown
Lol at "Can we trust the Peano Axioms?"
I don't trust a shady Italian.
I only trust my accountant. If he tells 2x2=5, then 5 it is.
Hey man, I know you love to solve these crazy integrals, but have you ever considered making a series in which you teach people to integrate, starting from the basics and building up the difficulty as the series goes on? Regardless, you are great and keep going!
I agree with this statement!!!!!!!!
that would be flammtastic
Yes please make it!!
Yes pls
I think he should teach advance integration, but if we’re talking about integrate x^2 + 2, There are many channels for that
41:15 Ahmed's Integral! Top 10 anime cross overs, that was really surprising
TH-cam: "Alright Papa I know you're starving so here are 7 ads just make sure you're family friendly"
Papa Flammy: *skullfucks a monster integral*
TH-cam: oof
There is no nice cancellation in the wild. Papa's just taught this to you.
Good job! ..Yes you can interchange the integrals due to the tonelli's theorem..notice that your integrant is a positive quantity(luckily!!) and also it turns out to be continuous(very lucky), hence is a measurable function( wow!!) hence you can interchange the integral signs.
that moment when you you are doing so many transformations, that I forgot what integral we were doing
Amazing man. Really love this channel
I came back to watch this video a second time to "train my attention", trying to watch it from the beginning to the end without losing any passage. It's a very nice and difficult integral, I really admire the fact that you don't use notes, I think I would not be able to remember such a procedure without doing it many times.
11:37 No, I can't. This time I would like you to prove 2 x 2 = 4 please.
This is just flamin' unbelievable !! What you are doing here requires great skill and discipline considering that your lecturing from memory without notes or cue sheets. Well done!!
37:24 :') Good old days of Fappable Maths
41:15 Wtf dude that was crazier than most crossovers 😍😍
Hey, random week 2.0 was great
Flammable Maths Find me one person who didn't 😂😂
dem engineer bois already attracted :b
FabFin Dude, I'm a med student and I'm addicted to Maths partly because of this channel. Show this to a Lib. Arts guy and he'd be attracted too😂😂
"Cocksetters integral"
Jim Moriarty whatever you want to tell me with that, I agree.
This was an absolute monster and you did a monstrous job. Really I rank this integral as one of the taughest. 🎉🎉
I really love this one it was awfully amazing.
My respect for not losing your shit filming this video, calculating stuff in your head all the time.☺
:3
40 min of integration MY DREAM CAME TRUE😍😍❤❤
I just started the video. This is above 43 minutes log but long time ago I knew a mate that evaluated this integral by exchanging "2cos(x)" for "tcos(x)" the he took the derivative of the whole integral with respect to t, made some cool simplifications then integrated with respect to x, uterly, he integrated with respect to t and found the constant.
Woo.
Great pun! “De-phi-ing” I laughed out loud at that. Well done sir!
You can justify interchanging the integrals by Tonelli's theorem, which allows you to interchange integrals where the integrand is non negative
Sometimes your equal sign looks like a minus sign
Dude this was sick! Your algebra is crazy
29:57 literally hand waving argument lol
It really means for me when solution of integral appears after 1 hour.Great
My god this is the best thing that I ever seen in my whole life cheers to you man
I'm glad you made a video on the first integral posted on that 'artofproblemsolving' page.
Waiting for more.....

Thank you sir for solving one of the best and magnificient integral which finally terminates into the Ahmed integral
bruh when he pulled that ahmed integral out i was like
*surprised pikachu face*
:D
You really showed Math is fun
Flammable Maths always ;)
His style makes it way for interesting
同級生からこの問題を出されて解らず困っていたので助かりました。
thank you so much!!
i was like yeah... i can give it a shot "took the paper, writing the question.... mid way of writing question..... No I can't."
I've been doing one MIT integration bee integral a day. I'm not able to solve every one, but I seem to be getting better when I analyze the solutions if I didn't know how to do that integral. It's a tough life...
That was inspirational. I was in awe of the size of this lad. Absolute unit.
Nice integral. It's useful to practice for some calculus tests. Continue like this man.
You can exchange the integral signs because of the Fubini theorem: you are integrating a positive function, so you can do that
I don't really know how to integrate properly, but god damn that was fun to watch.
Sees notification,
clicks on video,
sees it's 43 mins long,
closes video.
Syke, I watched it all!
XD
Why doesn't this have enough views? This is fire
This is perhaps the most interesting math channel on youtube.
Honestly I watch so many videos where people pronounce it “zed” that I now do it lmao
Are you American?
Zed is perfectly normal
Welcome to Canada
FUUUUU, finallyyy de 40min intigril :^*
Sugoi papa.
HOLY CRAP 45 MINUTES
Coxeter got torched. Well done paypay flemmy
I have ZERO idea what was going on, yet I watched a 45 min math problem and now I legit feel bad for him. This is WILD.
He could have written anything and I would have believed it.
:DDD
I watched rick and morty so I could follow every step of this integration papa
When you realize the nummerical solution is calculated within a minute and gives the same result
Ohh monster boi!!Thank god finally ...
Ikr..
Jokes apart Jens you are definitely my inspiration to make my own channel in future..Thankyou!!
The big f'n square root at 8:55 really made things easier...
Press F to pay respect.

absolutely crazy. Thank you.
my wrist's gonna hurt tomorrow
Papa's theorem. Every function from R to R is integrable in elementary functions.
Proof: Come on!
interchanging the integral signs is called fubini's theorem
I can’t solve the integral - Panic
There’s a video about it - Calm
43:13 - Panic
I can't solve the integral - Panic
There's an online integral calculator with steps - Calm
"The calculation was aborted because it took too long." - Panic
Who dislikes this wtf?
If I were to dislike it, it would be because of the ridiculous number of ad breaks.
@@Gold161803 it's a 40 min vid so it's fair
@@ifteharulhaque2600 Not really. Every other 40 minute video I've seen has 2 or 3 ads, and maaaaybe a fourth at the beginning or end
hehe 69th like
papa flammy is gonna haunt
those who dislike this masterpiece
31:30 pappa, you've interchanged the integrals long before this point even though you didn't write it up.
Gauss did this for fun and Fermat executed this in 13 steps but could not fit it all into margins in Gauss's book.
That would also involve time travel.
Can you please make videos on solving differential equations using Laplace Transformation (and then inverse Laplace)
The most fabulous 43 minutes of my life
At 9:30 I just used the triangle thing. Absolutely no idea what you were doing there lol but I got the same thing :)
That's the final boss of integrals.
Okay Papa, I give up. It is 33:01 and my brain turned off. I think that's too much for me xD By the way, I think you should have had 8/sqrt(3), not 8*sqrt(3) at this point (I am not sure though). Thanks for your sacrifice (I cannot call this video anything else)
Apparently, your brain did not last much longer than mine xD 39:55 Papa's machine going offline
You know... You mad man. I love u
Same Spiel down here😂😂 8:18
Increible, fantastico, asombroso......
4:12 my OCD went crazy x-----------------------x
Meanwhile here I am still having not learned how to compute derivatives or antiderivatives of inverse trig functions. This seems like the final boss of integral problems.
I'm loving this organized chaos.
Whenever you phase in from the left side of the screen, I got lost. 😂😂😂😂
xD
Holy fucking shit! 45 minutes!!?? Damn... That is one hardcore integral...
Need to append the Ahmed integral video into one video for completeness!
At 23:40 shouldn't the upper and lower bounds change with a change in variable from t to \phi
Really impressive man...Could you evaluate 1/3 factorial? Using Γ i showed is equal to int from 0 to inf of e^-x^3 but the i don’t know how to continue
You do this integral in the style as Andrew Wiles solves Fermat's last theorem.There may be easier way of doing this integral.Anyhow the proof is quite interesting.
amazing
22:30 So you _think_ you gpt rid of the 3.... but in reality it hid under the pi.
bruhv
You are my hero! BTW, are you Australian?
That was truly a coxeter integral
Can we really assume cos (t) / sqrt ( 2 - 3 sin^2 (t)) as a constant?
Such a fascinating video .... But what was the book in your hands 0:19
Imagine If this integral is in your compulsory 5 mark question 🤪
Nice way to end this random week. When will be the next random week?
uwu ahmed's integral at the end!
That was unexpected
at 29:00, you did not put (x^2 + 3 ) in the denominator when doing the substitution of 1 / ( 1 + u^2 )
Sometimes it is difficult to understand some steps in your videos, but after investigating I can understand them a little, for this reason I would like to know if there is a list of topics that we need to know in order to fully understand all the steps when you solve those spicy bois and those beach bois integral's in your videos. I am a second semester student of electronic engineering, I know the differential and integral calculus also linear algebra and a little bit of multivariable calculus.
Greetings from Valledupar-Colombia.
Thank you
next random week when? :'(
That's your masterpiece
Sorry I don't understand where the 2x disappears to in the expression at 4:13. Does it just happen to equal 0 through the variable substitutions or is there another explanation?
Yeeeee
I'll stick to my calculus 1 exercises for now thx
Imagine if the camera ran out of battery and he didn't notice...
Papa you're insane, how do you come up with this sorcery? Fucking insane
Did you figure it out?
Hmm it’s been a while but can we not use complex analysis to do this integral and make it be less steps?
I was watching this at 3 am and accidentally fell asleep while watching. idk
Oh boiii, look at the length :o
so long it hurts :^)
Wow your very wise. Can you recommed some math book???
Seeing whether this has a complex answers or we could call in quaternions
#Hard 2 swallow pills:This Integral.
Can we integrate hyperbolic functions
I must have that T-shirt, please tell me what to do
