For any circle:
a r c = r a d i u s θ
Where theta is in radian.
From the given data:
θ = a r c / r a d i u s = 0.009 / 2 = 0.0045 r a d i a n s

Recall that the length of an arc of a circle and the corresponding angle subtended at the centre are proportional.

Suppose I'm given two points: ( x 1 , y 1 ) and ( x 2 , y 2 ) (which are real numbers) lying on the circumference of a circle with radius r and centred at the origin, how do I find the arc length between those two points (the arc with shorter length)?

Let
f ( z ) = z ( z a ) ( z b ) ( z c ) ( z d )
be a complex rational function and let S = { z C : | z | = 1 } be the unit circle.

My question:
For which (non-zero complex numbers) a , b , c and d there exist an arc C of S such that f ( C ) S ?

I am attempting to determine the locus of z for arg ( z 2 + 1 ). I do know that since z 2 + 1 = ( z + i ) ( z i ), I could write arg ( z 2 + 1 ) = arg ( z + i ) + arg ( z i ) but I don’t really know how to figure out the locus of the points from here. How should I approach this? Is there a relationship with the difference in two arguments (arc of a circle)? Thank you!

Let n points be placed uniformly at random on the boundary of a circle of circumference 1.

These n points divide the circle into n arcs.

Let Z i for 1 i n be the length of these arcs in some arbitrary order, and let X be the number of Z i that are at least 1 n .

What is E [ X ] and V a r [ X ]?

Any hints will be appreciated. Thanks..

(By the way this problem is exercise 8.12 from the book 'Probability and Computing' by Mitzenmacher and Upfal)

It is not possible for a part of any of three conic sections to be an arc of a circle.
It is asked to prove this theorem without using any notation or any modern form of symbolism whatsoever (algebra). But, to me, this seems to be quite a difficult task. How can this be done?
