comment Is $1-\sin(x)$ a contraction mapping? And is there a sufficient/necessary condition for a real-valued function to be a contraction?
sorry, you haven't answered if $1-sin x$ is a contraction mapping.

comment Explanation and Proof of the fourth order Runge-Kutta method
Why do you writing $\alpha, \beta$ here $K_{2} := hf(t+\alpha h,x(t) + \beta K_{1}).$ If we expand $x(t+v_2h)$ with Taylor series we get that $\alpha = \beta = v_2.$ I mean, why do you use different letters for the same quantity.

@JessicaK , just to make image more demonstrative. Jump can happen even with small $\epsilon.$

comment Parabola equation in Fortune algorithm for building Voronoi diagram
@ErickWong scale-invariant, huh! i think you can form it as an answer:) Only i don't understand why they need the equation to be scale-invariant.. And why with exactly this divisor?
