 Apr12 awarded Inquisitive Mar20 comment Evaluate $\int \frac{1}{x^3+3x+1}dx$ Actually, $\frac{1}{z}$ is not $\log$'s derivative everywhere... Remember that $Ln(z)$ is not entire. Mar20 comment Evaluate $\int \frac{1}{x^3+3x+1}dx$ nice, was just about to post this idea for a solution. Jan13 comment $\delta$ = min {1, $\epsilon$} works for proving $\lim_{x->0}$ $x^3$ = 0? Nevermind Did, ok? I'll delete whatever I said. Dec20 awarded Constituent Dec20 awarded Yearling Dec17 revised let $(a_n)$ be a sequence of real numbers such that $|a_{n+1}-a_n|\leq \frac {n^2}{2^n}$ for all $n\in \mathbb N$. Then I messed up Dec17 revised let $(a_n)$ be a sequence of real numbers such that $|a_{n+1}-a_n|\leq \frac {n^2}{2^n}$ for all $n\in \mathbb N$. Then added 77 characters in body Dec17 answered let $(a_n)$ be a sequence of real numbers such that $|a_{n+1}-a_n|\leq \frac {n^2}{2^n}$ for all $n\in \mathbb N$. Then Dec17 comment Number of functions from domain to codomain @Mark sure no problem. Dec17 comment Number of functions from domain to codomain @Mark There are $b^a$ number of functions. Dec15 awarded Nice Answer Dec11 answered How is the area of this triangle calculated Dec11 comment What does non-zero integer mean? do you know what zero is? do you know what non is? Dec11 comment What is a counting number? hahhahhahhahaha Dec9 awarded Caucus Dec4 reviewed Approve A difficult trigonometry problem Dec4 accepted No-where dense sets in the reals Dec4 comment No-where dense sets in the reals @bof That makes sense. Yeah, I didn't think very deeply about the question... Dec4 comment No-where dense sets in the reals @AsafKaragila Yes!!! those are the things that I mean by that. I guess weird to me is just simply things I have less familiarity with. I've played with vitali sets, and cantor space a lot-- fat cantor sets yeah, those are nice. But bernstein sets! I need to play with those some more... I'm a newcomer to desc. set theory so weird means unfamiliar :)
