Nam makes a attempt of defining finite-number #339; Correcting Math
Nam Nguyen wrote: You've challenged few of us to come up with the definition of "finite- number" or else you'd go on with your ignorant babbling. So here they are, the definition of properties Finite(x) and Infinite(x): P(x) <-> Ey[y <= x) (*)P(x) <-> P(x) /\ AyEz[(y <= x) -> (z < ... 25 Jan 2010 01:48

bisecting quadrilateral to get rhomboid, proof
I bisected the sides of a quadrilateral, and connected the points of bisection, to produce a geometric object that I want to prove is a rhomboid. Where any adjacent sides are unequal, and where the angles formed are not multiples of pi/2. I did this in a very ugly way by fixing the center of a quadrilateral at ... 25 Jan 2010 17:22

Number Representation Problem
How can I map an integer N between 1 and 1,000,000 to a string f(N) of 12 letters where I can map back from f(N) to N, and f(N+1) bears no resemblance to f(N)? (Better yet f(N+m) bears no resemblance to f(N) for m=1 to 1000 or f(m) for any m not equal to N.) C-B ... 21 Feb 2010 03:50

Number of digits in factorial
Hello everyone. I am trying to solve a programming problem (https:// www.spoj.pl/problems/LENGFACT/) which ask for counting the number of digits in factorial N, N<=5*10^9. I used Stirling approximation and gamma function approximation. Here is my python code but i am interested in mathematical part. How to solve th... 17 Feb 2010 00:25

Cubic equations and companion matrices
I tried to have a deeper insight in the splitting field of a polynomial of the form f(x)=x^3-p*x-q for rationals p and q. First of all I considered the companion matrix of this polynomial: 0 0 q 1 0 p 0 1 0 Let's call it M. M satisfies M^3-p*M-q*I where I is the 3 x 3 identity matrix. This matrix ... 24 Jan 2010 12:27
