This is not a circle.

[Anonymous No.4074277]

x^2 + y^2 = 1

but that is

[Anonymous No.4074276]

Yup, it's not.

[Anonymous No.4074297]

>>4074277
thats an equation

[Anonymous No.4074299]

>>4074277
It's made out of little squares. If you trace the perimeter it won't be 2*pi*r

ur mums a circle cuz shes that fat !!!

stupid NEWFAG !

because the number of points between integers of a graph are infinite, a mathematical circle can be considered perfect.

No, that's a picture of a circle.

you sound like a homophobe. An Engineer only cares about the required precision. You obviously hate engineers.

It's a picture of two concentric circles: One white, the other black.

[Anonymous No.4074324]

That is, in fact, a sentence.

the black one is a cylinder, not a circle.

[Anonymous No.4074361]

You're right OP. It's a torus.

[Atwill !kelPcGZQlE No.4074364]

The OP is not a faggot.

[Lightning !gYjELVKQn6 No.4074369]

Interesting thread we have here.

[Anonymous No.4074370]

My definition of a circle: a set of elements from R^2, where there exists an x in R^2, and an r in R, such that for every y in the circle, |x-y| = r

so it's not a circle, because the line is too thick. the points at one side of the line have a different distance from the middle than the points at the other side of the line.

What about r = 0?
Is that a circle?

[Anonymous No.4074383]

>>4074299
it's a circle of squares.

[Anonymous No.4074385]

>>4074370
SHIT. I mean sqrt(|x1 - y1|^2 + |x2 - y2|^2) = r

>>4074373
you mean a singleton is a circle? why not?

[Anonymous No.4074391]

I just wish I knew what OP intended this thread to be.

>>4074370
hmmm, now that I think about it more, it seems this isn't a correct definition after all. A half-circle is admitted as well. Never mind me then.

Ce n'est pas un marteau, soit.

[Anonymous No.4074408]

Sounds good, because it also works for non-euclidean metrics.
Say, taxicab: <span class="math">d(x,y) = |x_0+y_0| + |x_1+y_1| + ... + |x_n+y_n|[/spoiler]

[Anonymous No.4074415]

>>4074408
Shit, it should be <span class="math">|x_i-y_i|[/spoiler], not +

[Fighting Irish No.4074455]

>>4074273
I don't understand the logic behind your statement, OP. How is this not a circle?

[Anonymous No.4074475]

Yup.

[Anonymous No.4074499]

>>4074455

Because "This is not a circle." is not a circle.

[Jenny !u4Ifr7Rpgg No.4074742]

It's not a circle, it's a polygonal approximation of a circle.

Pixels.
