Draw A Perfect Ellipse

[EmSarahx]

i was looking for some art not fucking maths...

[Bogrune]

The conics and their many properties like their foci.

Where will we ever be without math!

thanks to the person who had uploaded this video

[MrJustsomerandomguy]

It is much easier using only paper or plastic line.

[tonyrosam]

i was wondering if an ellipse can have a perfect 3 to 1 ratio diameter to circumference or is it also an infinate ratio like pi.

[MasterMisterPoopy]

not sure thats easy... but cool

[markdave3]

it would be useless for me since im look for unholed -__-

[bradleychow2000]

Yea a perfect ellipse yea with 2 holes in it



[thorne279]

@bradleychow2000 en ellipse is a 2 dimensional figure. The key word here is "draw" meaning it's a picture, or a rendition. There are no holes in the ellipse, there are holes in the paper, which the ellipse is being illustrated on.

[starmanian]

old school :)

[silvercomet1735]

Ok, this sorta bugged me: It technically isn't a mathematically perfect ellipse due to the elasticity of the string and the size of the toothpicks. It is, however, close enough for most purposes provided you don't use anything stretchy (like a rubber band) or big like candles (instead of toothpicks).

Yeah, I'm going to get down-voted for this aren't I?

[Whitecroc]

@silvercomet1735

*Physically* impossible would be a better way to phrase it.

[SanctumZero]

Shit looks like a circle. Should user wider focal points...

[JohnnyTakeAll]

@SanctumZero If you say this simply to mean you want a better example that this is in fact for ellipses, than I agree, however this ellipse just has a low eccentricity, so appears more circular...Buuuuuut I think you already knew that (just a lot of people are commenting on the whole "circle" thing)

[EthicsofAmbiguity]

Every carpenter that has made a table top knows this.

[EthicsofAmbiguity]

This is a better example. watch?v=hp7AxUVX714&feature=re­lated

[googledude23]

but you ruined your....why wouldnt you just buy a damn compass?

[EthicsofAmbiguity]

@googledude23 Because a compass makes a "circle", this is to make an "ellipse".

[acme420]

nice video cept thats not an ellipse, thats called a circle. an ellipse is the shape the string was in before you put it around those 2 toothpicks and drew a circle.

[xXxUnSlashAble]

@acme420 it has a slightly different curvature than a circle.

[sweet89090]

@Moonangel75 its a oval

[monkeydude12347]

brb let me grab my 2 toothpicks and rubberband i carry with me

[tuhkur102]

draw a face, erase some lines you drew, you have a circle

[silydog1]

O.o

[f937r]

I just use my finger as a compass guide and spin the paper. Works just as well.

[onewhoisrad]

@f937r  but doesnt that just make a circle?

[Murgocyu1]

lol:))

[TheJimzhe842]

Awesome, but you have to punch holes into ur paper for the toothpicks

[turbotonic27]

then you woud have a paper with 2 holes

[ThisIsOrrick]

cool! :D



[EdouardDubois]

Sorcery! He's a WITCH.

@EdouardDubois If he weighs the same as a duck, he is made of wood; and therefore... a WITCH!

[brodman48986]

@bruno2260 small pebbles!....woood!

[edelart]

So smart thanks for sharing!

[Typho0n86]

hows that easy, you got to stick 2 holes in ur paper :S

[MrMapleFreaks]

:O pro!

[PandaMagicFTW]

its not a circle cuz if it was a circle there would only be 1 toothpick

[aylera]

Ooo wow, went for a perfect circle, only to be left with unusable paper because of the two gaping holes in it..

Its a circle, not ellipse, and its not math, its physics.

Math is not the language of the universe, amount is. Math is only the language used to communicate amount.

[IllRockYourSox1]

its called a circle...

[Blckoctobervoclz]

@IllRockYourSox1 ellipse means circle, dude.

[Behindspace90]

@Blckoctobervoclz

Ellipse does NOT mean cirle, dude.

[Blckoctobervoclz]

@Behindspace90 In geometry, an ellipse (from Greek ἔλλειψις elleipsis, a "falling short") is a plane curve that results from the intersection of a cone by a plane in a way that produces a closed curve. Circles are special cases of ellipses, obtained when the cutting plane is perpendicular to the cone's axis. An ellipse is also the locus of all points of the plane whose distances to two fixed points add to the same constant.

technically, it's a circle

[Behindspace90]

@Blckoctobervoclz

Yes, I know and confirm that. But you said that an ellipse is a circle, which is false. A circle is an ellipse on the other hand (the other way around).

When speaking of an "ellipse", you aren't per sé speaking of a circle. But vice versa it is the case.

[anisha1794]

stupid :( i cant use that in my graphics exam...

[olvvvvlo]

Looks to easy that is even simplistic. But I can´t use that in the test

[AL5a6f]

hhhhh put only one

Easy

عود واحد ومايحتاج الفلفسه الزايدة خخخخخ

[c0ddlefl0p]

Thats a circle, not an ellipse..?

[FearTheL33t]

Our definitions of ~easy~ seem to be very different.

[pitelis]

yeah x^2/a^2+y^2/b^2=1 !

[imilkdude]

i love u, i want ur babies

[multismoothcriminal]

OMG i wanna kiss who ever made this! xD

I had this as a homework to be sumbitted tomorrow, and i didn't have any idea about to draw an ellipse! lol, i was thinking of a compass, to be frank! xP

ahaha, i'm such a loser, thank you so much Mezon Biz! =P

[spiceb2008]

Hey i made it, can i get my kiss now lol

Actually the mathematical way to draw a perfect eclipse is using a compass and calculations..

[bravebacker]

simple way for a simple ellipse

[vintalation]

thanks man

[roen90210]

Math is beautiful...

[ultravegeta323]

OMG, thats hard to do without the needles, holy fuck, awesome

[gerardrondeau]

méthode pratique pour éxécuter l'éllipse (du jardinier).les points ou sont plantés les clous se nomment foyers.

[zaldude]

cool!

[pgeeme]

very nice

[therealTOTOfan]

@catsruledogsdrool23 second ;D

[1NIKOLETA]

thats a good idea :)

x

[EMINEMFANNAMEJINO]

lol!!great trick!brain trick O_o!lol XD

[ClaudioArrau]

This isnt magic, just math.

If you let only one needle, then you draw a circle

[househoffer]

incredible!!

but... How can I make it without the needles? (for a book for example)

[hipgang2007]

haha, you can't :D

[theigneo]

magic.

[tupulecaca]

that waz pretty neat ! good job
