Ah! I finally understand how they came up with that. Understanding why the formulas work makes math more fun
wow it's unimaginable how animation can be way more effective in conveying complex ideas such as this compared to teaching with merely words, numbers, and drawings alone. I really hope one day I could learn animation too!
Does this suffice as a rigorous proof of the statement that math=art?
I am so with you on that statement! Math needs to be taught creatively, not this BS that has been going on for centuries.
rigurously, it's more like math ∈ art.
@@Joffrerap Nah, it just shows that math and art have a non-empty intersection.
Hmmm... Is there an explanation for where the formula for a cone comes from? Everything else is great!
In this video I assumed that we already know the formula for the volume of a cone, however it can also be found using Cavalieri's principle.
if anyone is interested i can make a follow up video on how to find the volume of a cone.
yes please!
@@ThinkTwiceLtu yes, would be great
Yes please!
We want
It's fricking beautiful! I love this content.
PLEASE do a video on the Taylor series.
I second that
Yep
3blue1brown has a great video about it
i think i found a way to show the intuition behind the taylor series, now only need to get good at animating. working on it right now :P
Avocado Sauce Why did I think of Taylor Swift when I read this?
spectacular video
Found this channel a couple of days ago and it's already one of my favorites. Really shows how beautiful maths can be :)
It is good to see that mathematics in the high level,easy to understand for students and also understand math very deeply .Thank you for such this chanel ,keep going on.
Very smooth! Subbed instantly
I've also known this method for many years. But out of many many ways of proving the volume of sphere this is without a doubt the most elegant and beautiful way in my opinion! :D
i've seen so many proofs for the volume of a sphere but this here has to be one of the most elegant proofs ever. great job!
Made my day! Content quality
It's great to see this Chanel getting sponsorship!
These animations which derive formulae visually are very helpful.
There should be a double like button on UA-cam, extremely elegant explanation.
wow, the animation is so clean and crispy. nice job!
Please keep posting I’m a math enthusiast and I adore these videos.
THINK TWICE, I MISSED YOU...
BRILLIANT WHY DO YOU HAVE TO MOLEST SUCH A CUTE CHANNEL
Channels _want_ sponsors.
@Gabe Catalfo What the fuck is that comparison? What does it have to do with the sponsorship relation?
Such a spectacular video, please do one on Taylor series.
This is getting better than mindyourdecisions.
Your videos change my underrstanding about formulas and derivation
It only makes sense to me if the principal is that = cross sections on the same bounded height => equal volumes but not the converse. IE equal volumes does not necessarily imply that the cross sections are always equal when bounded by the same height.
Which is what you said.
But when I first watched this video I for some reason read it the other way, and had a bit of a debate to myself, oops.
Yes, example a paralelopipedid (I don't know if I wrote it right) with volume 1
Glad it makes sense to you! You are correct that shapes with equal volumes may have different areas at cross section, but if they have equal areas at all cross sections, then their volume will be equal.
I'm baffled; the simplicity is magnificent. Well done.
Great visualized explanation as always! :^D
I wish they teaches these back when I was still in school...
Blindly memorizing the formula? More like "you'd better shove these pile of symbols down your throat, without us explaining it thoroughly why it is like that then vomit it out on the test or else you won't get past jr.high" memorize... x]
Where I live... Let's just say the education system is *very* underdeveloped and extremely outdated...
Cavalieri is older then the way we do integrals now
Simple, beautiful, to the point. This is quality content.
Here from Flammy!! Love the ambient atmosphere you create lol :D
ThinkTwice and 3B1B. Leaders in Visual Mathematics! :)
This also indirectly shows another cool circle thing, which is that if you have two circles with the same center (a flat donut, like your cone and cylinder), and you take the distance from the inner circle to the outer circle along a line tangent to the inner circle, and make a new circle with that radius, the area of that circle will be the same as the area of the flat donut. Or, to put it in the terms of the Car Talk puzzler where I originally learnt this, if you measure a carousel from edge to edge with a line that just meets the inner hole, it will take the same amount of paint to cover the deck of the carousel as it would a circle with that diameter.
underrated channel for such mesmerizing content
Holy crap…this is mind blowing
*Mind Blowing*
There’s a lot to like about all your videos, but I really like the color palette you’ve stuck to.
Seth Bracken thank you:) Sometimes I spend an hour or more just picking the colours for the animation
Personally, I like the calculus proof of that equation better because I feel it leads to a better understanding of calculis and also of why the formula looks the way it does. But this also nice.
Nicely done! I can't imagine a better way to find that formula.
I like this. Especially the music! 😁
Your videos are one of my favorite things on the internet, they are really awesome, thanks for making them
rodrigo thanks a lot:)
Best math channel !!!
Yay! I'm so happy to see a notification from you! Let me watch the video now.
absolutely beautiful. simple and efficient.
Elegantiška, paprasta, gražu. Super Think twice
Elena Jonikiene ačiū :)
it's brilliant! thanks for making this vedio. it was really helpful to prepare shcool presentation!
Superb...easy way to learn
You won a subscriber
i love this channel, it really help us
Thank for this , I am really amazed
This is beyond satisfying
Cute lil shapes💛
Absolutely love it! Seen all your videos
beautiful explanation, thanks!
I HAVE A DUMB QUIZ ON THIS TOMORROW AND I DONT KNOW ANYTHING BUT THANKS
Mind = Blown
Utterly satisfying
Your videos are best
Well, it’s obvious that your work is frickin beautiful and very much inspiring! If you don’t mind me asking, what animation software is it that you use? I plan on using some visual representation for some school projects (:
Cyrill Thank you! I’m using processing and cinema4d for my animations. And then I just edit everything in a video editing software like adobe premiere pro
Wow, this was surprisingly good!
This is art I love it so aesthetic
You could have kept the cone pointing up the cross section animation would be easier to understand. Still great work love the channel
I love your content and i appreciate your efforts ❤️❤️❤️❤️❤️
OHH SHEEIT NEVER REALIZED THAT BUT IT'S SO PERFECT
Simply beautiful!
I get nothing but I do like to watch this videos
"Blindly memorizing formulas", perfectly describes modern math education.
I don't really see it, tbh. I tutor on the side and remember high school and university quite well, and very few times were we meant to just memorize stuff. There was always some aspect that aided in memory and the methodology was just as important as the answer
Nice!
very interesting. thank u
W video , helped with hw
Great! I appreciate it.
People more interested in this principle should watch the video on Napkin Ring problem by Vsauce. He uses the same principle to explain the concept of a napkin ring.
This channel is great!
Great video! Hope u are feeling better now.
thank you
These videos are amazing, you've earned that 200:1 like:dislike ratio
Best channel
another amazing video!!👏👏👏👏 keep going
This is such simple integration, you don't even need to name this a principle, this is just common sense calculus.
These videos are so great!
Minionology for You! thank you:)
Super cool.
Thanks 👍
oh look another maths/science channel I'm subscribed too is sponsored by brilliant.org.
. . . didn't see that one coming
Superb.
Very nice
How do we know the radius of the one is equal to its height? I’m assuming it has to do with it being made based off a hemisphere but can you show more specifically
I always wonder why the surface area of a sphere is the derivative of its volume.
can you explain why? great visual interpretation by the way
edit: is there any other way to get the surface area formula beside derivative?
Beautiful!
I am your new subscriber. And i think your channel is so amazing i cannot describe. Please tell us which software do you use for creating these slinky animation.
I am a mathematics teacher from india and i too use animation from adobe after effects but they are not quite amazing plus they are time consuming
Please tells us the name of application you use
How do you make these animations?
what program do u use for this videos , I wanna do videos like these .
awesome video :) keep up with the good work!
01:14 I thought there is a typo in the word "hemisphere" and that there should be "semisphere".
But "hemisphere" is also a correct word (it comes from the Greek word "hemi" which means "half" - the same as Latin word "semi").

Lovely!
The one showed up again 💙
What do you think about the Atiyah Riemann Hypothesis?
Make a video on Bassal problem
Loved it
Holly shit!!!
I am stunned!
Nice paradox
Do the cone volume
Pretty good!!!
You are the best
