Andrew’s integration skills make me feel smarter
If there's only one thing I know it's that \int lnx = 1/x

Are we not talking about flammy just being a dumbo with d^2/(d^2+1)?

"Everything is convergent if you're brave enough"
I'm definitely taking this attitude to my next calc exam
No don't
I dare you to use the Riemann series theorem (or whatever it’s called) and just rearrange terms to show every divergent series converges to 69. ;)
ikr
@@sigmundfreud4472 Nice. And username definitely checks out.
Your prof be like: "Everything is a failed exam if you're brave enough"
"-420 is approximately zero"
"yeah for small values of 420"
lmfao
No I missed the moment this comment reached 420 likes
@@Smitology it still is at 420 for large values of 420
I never knew I needed competitive meme integral solving, but I need it
:D
There is nothing better than trying to solve integrals while a german guy laughs at you, it is definitely as good as it gets...
Clever memes:
Flammable Math:
"Your sister could be dead":
Flammable Math: LMAO DEAD SISTER
:D
12:07 "proof by knowing what the answer is" lmao 😂😂😂
7th grade me wished i could have used it
"Anything is convergent is you're brave enough"
I try to live my life by that marvelous phrase
Spoken like a true physicist
If this is the level of humor you acquire when doing maths then I'm never stopping doing it.
:D
It does come with some problems...like trying to convince anyone other than other mathematicians that you are sane.
Please keep this series alive haven't laughed this much in a while. Really keep this series going ahead.
:D
@@PapaFlammy69 can you integrate the gamma function please
Dude, the last one's trivial. e = pi, so the integaral evaluates to zero.
they are making that joke in the video sir
When you realise that he could have just drawn some triangles to find the area under f(x) = x
I'm so happy that I'm not only who forgets if int ln x = 1/x or int 1/x =ln x
"Whalecum to another video" 😂
AGGHHHHHH
🐋 💦
Andrew: *breathes*
Jens: "Haha you laughed!!!"
:D
Favorite quote of the video: "Proof by knowing the answer".
xd
Me, an Aerospace engineer student: "Mhh, I see nothing wrong here."
"Everything converges if you wait long enough" ~ Andrew Dotson.
Jens: Good morning fellow mathematicians
Me (A mechanical engineering major): *Nervous sweating*
For the last one i used the "area method" since x is a simple function and the shape of area is just a trapezium
= (f(π) + f(e))(π - e) / 2
= (π + e)(π - e)/2
= (π² - e²)/2
= π²/2 - e²/2
Ikr idk why he didn’t graph it Lmaoo
Yeah. The area method is really simple. But it might be too easy.
Engineers: Where's the table??
Honestly true. I thought. These techniques and what the heck is a sec^2. That's gotta be in a table. Otherwise I am lost. I call it proof by someone elses work
@@HormersdorfLP LMFAO
"Everything converges if you wait long enough." Spoken like a true physicist Andrew.
Andrew’s integration skills are making me wish that I stayed in my mathematical career.
You can always use the mail.
It’s never too late to switch.
Andrew laughs while internally dying at 9:28 after being reminded of massive American college debt oof.
I hope for him that it's not that bad
Nobody:
Not even Americans:
Jens: "Hee"
Yet it is CORRECT !!! I'm Greek so ... I know how to pronounce it
Shut the fuck up about "nobody" already
INCOMING ANGRY EUROPEANS
Andrew is proof you don't need calculus to do physics
I mean he was probably rusty on integration or something, cuz you can go a long time without encountering serious integration while doing physics.
But when you are solving real problems, you better know integration.
@@takeuchi5760 you can study maths and go a long time with out integration
@@leoman5481 Yes except that the connection of branches in mathematics is just a mess, like for some reason the zeta function which is defined in the complex numbers gives information about the distribution of primes, which is dealt with in number theory. You just cannot say that you will never encounter integrals if you are a professional in other branches of mathematics.
This is absolutely amazing! as someone who enjoys integrating but doesn't love it, it was an amazing way of practicing, I paused and solved each integral with you guys! Although it began as procrastination I ended up practicing!!! And my exam is in 3 weeks!! Thanks!
"good morning fellow mathematicians, welcbaktnuda veedio"
accurate
19:22 You could have done +1 - 1 in the numerator and split the fraction
It will become Integral of [1 - 1/(d²+1)]
So that will be d - (arc tan d) + D
Is one a nerd if one finds this genuinely entertaining?
nope
no
Yes. Source: am a nerd and finds this genuinely entertaining
nah
No. Source: I find this genuinely entertaining but I'm dumb as a brick.
"python can't do things like 420^71"
ah, you appear to have forgot about one of python's coolest features, unbounded sized ints!
I put the first integral into wolfram alpha and it told me “no result found in terms of standard mathematical functions”... holy hell
New result didn’t drop
"Reading the rest of the meme is left as an exercise for the viewer" killed me
This is unironically awesome practice for my test tomorrow as a calc2 student
“Take a deep breath such that you don’t laugh”
Dude, a great collaboration! Awesome to see you guys at it again!
For small values of 420 it is approximately 0...
Seems legit
Definitely doing this with my friend as a preparation for our upcoming calculus exam! 😂❤️great inspiration
Dude that is a brilliant study strategy for many classes, now I just need friends
I’ve never seen someone so excited to show off their integral collection
Awesome video :D
Integrate x dx. Everyone: it's x^2/2...
Him: let's substitute bs here and use e^some more bs.
19:44 that is the easiest integral of the whole video just +1 and -1 in the numerator and then separate the denominator, thus then you have to Integrate dd and -1/d^2+1 dd so the answer is d - tan^-1(d).
+C oops
I watched the whole thing. Loved every single part
The collab i've been waiting for
more of these videos needed
Number 9: just write d^2 +1 -1 kid flammy 19:20
Was gonna say... simplifies to d-(1/d^2+1) which are both standard integrals...
u still need tan substitution to integrate 1/(d^2+1)
@@tupoiu Not if you just say it is tan^-1 and leave the proof as an exercise for the reader.
As I was saying, standard integral
Flammy please do more of these, this could be such a good series
maybe with zach star?
Absolutely awesome!
Just sayin', but you could've just rewritten it like this instead;
(d²+1)/(d²+1) - 1/(1+d²)
and avoided all that monstrosity lmao.
30:54 Damn that's a surprisingly correct way to pronounce 'χ'
:)
@@PapaFlammy69 as a Greek I AM PROUD OF YOY
Make more of these videos they are great.
Bruh this is so creative. LOVE IT
8:31 it converges uniformly 😎
I want to be as confident as Andrew!

"Eins... Epstein's theory of heat capacity"
Wtf!?!?!
daily reminder that heat capacity didn't kill itself
Andrew killed Epstein
this stuff reminds me of my time doing personal tutoring, amazing :D
Holy canoli we have received yet another comedic addition to this lovely site
8:35 You can't interchange the limit. As written, you are asking for the limit of a constant number, so for example you could replace that limit with one approaching 72 and your answer shouldn't change. But by interchanging, you are taking the integral of a constant, and this constant does depend on the value the limit is approaching, but that wouldn't be the case if you were free to interchange them through the integral.
You are playing too loose with dummy variables. The definition of the definite integral requires that its dummy variable be free to vary throughout its region of integration. When pulled inside, the limit that uses the same dummy variable places an additional restriction on the dummy variable that breaks the original definition of the definite integral.
My thoughts exactly, the area function limit might differ for the general case
Yeah, that integral didn't make too sense honestly. Letting a variable approach a constant but also integrating with respect to the same variable? Doesn't really make sense honestly
You were right about question 9!
Love the Forest Haven music in the background.
Jens and Andrew: *struggle when using common letters as variables*
Greeks: First time?
NOTICE ME PAPA FLAMMY
Oh I just realized you put Child of Light soundtrack in the back! Thanks, I love it
This humour is so niche, i dont know how i reached it but i love it
This gives me life
The solution to integral 3 was super cool!
Please make more of these
That dd integral gave me a stroke
@ 8:24 You can't interchange the limit and the integral in this case because the limit is respect the variable you are also integrating. If you work it out then you find that the answer is approximately -0.00543 (\int_42^111 sin(x)/x dx).
This video cured my depression , flammable maths laughing is the best therapy
OMG Papa Jens, I think you made a mistake! Are you sure about interchanging the limit and the integral at 8:20? The evaluated integral does not depend on ∂ anymore, so the answer would be something with Si(x) because you could ignore the limit.
The way you are doing it, you should include the d∂ in the limit, but then the integral would not make any sense.
Whatever he did there was definitely not correct lol. Since the integral from 42 to 111 is already a constant which does not depend on the variable, the limit would just be the constant. So the actual value of this limit would then be approximately -0.0054 according to wolfram alpha.
The notation was ambiguous to start with, so one could argue that the ∂ appearing in the integrand is not the one from the integral, but the one from the limit. XD
It's like taking the limit as x-> 0 or 6.
@@adamjennifer6437 Fucking bot.
I love that music from Child Of Light from the beginning!
Hello Papa Flammy ! I really love what you do on your channel ! This concept is soooooo cool ! If one day I want to reuse it, can I ?
Keep doing the great work !
You and Andrew are hilarious 😂😂 I cracked up every time Andrew had to say “approximately” when he had to integrate with respect to approximately. You guys should definitely do another one at some point.
Oh my god I need more
Hey Papa, are we having another Mathvengers special this year?
I really love your videos btw!
This is a useful and instructive video contemporary! :)
andrew you are the king fr
A great play along at home game!
That's best idea someone ever had
:p
honestly, I was laughing more about how you calculated the integrals in Dotson manner, than about the memes :D
The last integral was a banger :o
7:39 I never knew I needed to hear a german gentleman say "that ain't bad, at all" so much but here we are
You uploaded this faster, nice.
Andrew can you please give a physicists explaination for why using the riemann approximation is the best way to integrate
Whenever I have doubt about my integrations skills watching Flammy's "hard integration" videos, I watch this.
Then, I feel instantly better about my skills lmao
MOREE!!!
Literally my conversation with another smart kid in the class.
For the d^2/d^2+1, you could add 1 and subtract 1 in the numerator, so (d^2+1-1), then split into 1-(1/d^2+1) which integrates into d-arctan(d)+C
this is the best video on the internet
Hey FM, this is one of the best formats you have presented. You can def. milk this cow.
But it's soooooooooooooo much editing XD
On a random note, I loved the Earthbound Zero music in the background
you could've just had him come upstairs instead of overlaying the videos
No he needs to stay in the basement
Evere heard of covid-19?
I love the artwork on the Mandelbrot set :)
same! :D You can get it over on STEMerch.com :)
Joke's on you, papa flammy. Python can calculate arbitrary large numbers, including 420^71.
f u c c
I hope both of yall teach my future nonexsistent children.
Hands down your funniest video 😂😂😂😂😂 Here's to your creativity 🥂😂
I genuinely think you would be the best Maths teacher of all time
The first integral is Coxeter’s integral. In Nahin’s Inside Interesting Integrals it was THE single, longest evaluation in the book.
Andrew's "Lamaze class" comment was lowkey the funniest thing in the video.
This dude is so happy just because he is math with his friend... I wish I had a friend I could do maths with...
your voice on integrating the dd one makes it even funnier haha
Literally laughed my ass off for nearly the entire video 🤣
