JindrⒶ, your locally Euclidean anarchist<a href="https://todon.nl/tags/Math" class="mention hashtag" rel="nofollow noopener" target="_blank">#Math</a> fact that doesn't sound right when you first hear it:The difference of two functions (of x) can grow to infinity while x -> infinity, yet their ratio can go to 1.Why it's interesting: We usually think that if the difference of two things goes to zero, they become identical. Yet, we also think that for if the ratio of two things goes to 1. So this looks paradoxical.
