So, I recently ran across a couple lovely YouTube videos on Perfect Numbers and their relationship to Mersenne Primes, and decided to fiddle around with some stuff in Excel. Now I'm wondering ... asking for a friend ... *cough* ... is it possible...
I'm trying to figure out how to make / use Trees in Mathematica. I've made my own very rough tree in Draw.io, but I'd like a more systematic / automatic way of doing it in Mathematica. But I'm not sure *how*, or whether Mathematica currently...
Seems like maybe Mathematica 9 didn't have AllTrue[] function. Anyway, I'm working with Pascal's triangle, trying to see if all members [except first/last] are divisible by the row number. I create a list or members, a list of divisibilities...
So, been trying to figure out how to do something, and researching it online, and came across the term "Primorial(s)"... Meaning the Product of the first n Prime Numbers. (Say, multiplying the first n=10 Prime Numbers together, etc.) ...
So, I'm trying to graph a parabola reflected across y=x. y=x^2 --> y^2=x or y=Sqrt[x], yes? Am I thinking about this correctly? It's been a long time... So, I write: Plot[{y = Sqrt[x]}, {x, 0, 50}, PlotRange -> {{0, 50},...
So, okay, here's my quandary, I'm working on a problem and have a solution for the even values I'm concerned with, but not yet for the odd values. What I'd like to do is to graph some range of solutions as individual parts of a 3D graph....
So, I have several functions I've been working on, and was hoping to find a more general form. I guess they're maybe a series, of sorts, or could be. I've been a bit out of the Mathematics game since High School and a little bit in College. So, I'm...
So, there are probably plenty of different things that COULD be analyzed about historical lottery draws (as a 'for instance': PowerBall & Mega Millions). I'm interested in some general statistics, I guess? & progression over time. All...
