 Nov22 awarded Yearling Aug14 comment Why learn to solve differential equations when computers can do it? My eight year old just asked me the same question about adding and subtracting. Jun17 comment How big is infinity? I would also recommend "The Quest for Infinity" by Brian Clegg. Highly readable, even for the non-mathematician. Jun10 comment How can Zeno's dichotomy paradox be disproved using mathematics? @user21820 Here's a simple discussion on it. fromquarkstoquasars.com/the-smallest-possible-length May30 answered How can Zeno's dichotomy paradox be disproved using mathematics? Apr22 comment If there are obvious things, why should we prove them? @n.1 Keep your cis-normative privilege out of it! Nov22 awarded Yearling Nov18 comment Limit: $\lim_{n\to \infty} \frac{n^5}{3^n}$ I'm not sure if I can do this, but I'll throw it out and see if it sticks. Nov18 answered Limit: $\lim_{n\to \infty} \frac{n^5}{3^n}$ Nov6 comment Is math built on assumptions? i is a definition. But it comes from a huge assumption: Assume we actually could take the square root of -1. If we could, we'd call it i. and the implications of that statement follow quite spectacularly. Nov4 comment Is 10 closer to infinity than 1? @TheChaz2.0 In the book, the stairs go up forever as well. Sep16 awarded Citizen Patrol Aug9 comment What was the first bit of mathematics that made you realize that math is beautiful? (For children's book) For reasonable values of all. Jul16 comment How to convince a math teacher of this simple and obvious fact? I would ask your math teacher to prove the assertion. That's how it works. You have already disproved it by providing counterexamples. Jul10 comment Proving $\frac{a^4}{b^3} +\frac{b^4}{c^3} +\frac{c^4}{a^3} \ge 3$ How did you get to the second line? It looks like it should solve down to x^8/y^6 >= 1 (take roots to simplify further). Something is wrong here, or there's a huge step missing. May6 awarded Critic Apr26 comment Probability theory problem The probability that A drew 5 balls is 100% since the question states: " A draws 5 balls" Mar20 comment Help creating a rational function I'd start by sketching out what I know. Draw the asymptotes and intercepts.
