There is a proper definition for a circle that is found in most calculus books.

Without googling or looking it up in your book, define a circle without using the equation/formula of a circle or any facts about any other geometrical shapes ("points" are allowed.)

Your definition must exactly define a circle and must not be applicable to any other shape.

How many trig. functions are there?

Op i will break it for you.

Infinite time means it has no beginning nor end. Like a circle thats how time goes, in a circle forever with no beginning and no end. The circle has no beginning nor end but still the circle has it's exact lenght.

Circles don't actually exist and cannot exist, and neither do circumferences, diameters, and radii.
Have fun playing with your imaginary friends.

> Imagine a circle anywhere in the universe. I can guarantee you that there are two points directly opposite each other on the circle with the same temperature.

How many sides does a circle have?

None of you will get this.
A cow is tethered to any point on a circle with radius x. Find the length of a piece of rope in terms of x that would allow the cow to move in exactly half of the circle's area.

Hey /sci/, would the distance required to reach the ending of a circle be zero or infinite?

Picture related, it's a circle.

ITT: We discuss the finer points of MATHS.

todays subject: cDonald's Theorem.

n^2 + 9 + 9

When plotted on a graph, it produces THIS strange figure.
Can you think of a name for it?

For which metric functions M will the set of all points p in a two dimensional space satisfying M(p) = x, where x is some constant real, be a closed curve?

(forgive me if I'm using the terminology a little loosely, but I'm sure you get my meaning)

One of these

pi=(2ln(i))/i
pi=C/D
C=2ln(i)
D=i
What would this be? Some sort of "imaginary" circle?

pi=C/D
pi=(2ln(i))/i
C=2ln(i)
D=i
What would this be? Some sort of imaginary circle?

Can a perfect circle ever exist anywhere but in our heads?
