elementary set theory - Is there a "nice" measure on the rationals ...
Apr 10, 2025 · So getting a result that we measure something the size of $\frac 19$ is not a contradiction unless we assume the "rational" size of $ [0,1]\cap \mathbb Q > \frac 19$.
Is there a general formula for estimating the step size h in …
Why should the step size depend on the point $x_0$? Two points might have the same neighborhood (e.g. for a periodic function, $f (x) = f (x + T)$ for some $T$) so their numerical …
