comment Interpolation between 2 points on the perimeter of a circle?
if the problem is with the use of $\sin$ and $\cos$, you can approximate them using 3-4 terms in the Taylor series

comment Interpolation between 2 points on the perimeter of a circle?
What does it mean "without use of angles"? Parameterize your curve as $x(t) = \cos (t\pi/2), y(t) = \sin (t\pi/2)$ with $0 \le t \le 1$ then $t=1/2$ comes out to $x = y = \sqrt{2}/2$

comment converting asymptotic little-oh into big-oh
If $f(n) \cdot n^{1/4-\epsilon} \to 0$ then $f(n) = O(n^{-1/4})$, not $O(n^{1/4})$ as you have claimed

that's not what it says in the question -- "10 out of every 1000 are defective" but i can see how you want to interpret it like that. i wasn't the one who downvoted btw
