monte carlo method for cauchy distribution
The cauchy ditribution has pdf f(x)=1/(pi(1+x^2)) In order to generate random observations for this distribution we need to find F^-1(u) which in this case is: F(x)=arctan(x)/pi F^-1(u)=tan(pi*u) -.5<u<.5 So, if u has uniform (-.5,.5) distribution than X=tan(pi*U) has a cauchy distribution. Is this ... 28 Mar 2010 23:22

proof involving FTC to double integral
(I'm using tex because I don't know how else I should express partial derivatives via this medium) I'm given the following: If \frac{\partial^2 F}{\partial x \partial y} = f(x,y) then \int \int_R f(x,y) dA = F(b,d) - F(a, d) - F(b, c) + F(a, c) Where R = [a,b] x [c,d] My question: by integrating the... 28 Mar 2010 18:59

every infinite r.e. set has injective enumeration: show injectivity
Hi there, Do recursive functions give unique values for 0? I'm trying to show that every infinite recursive enumerable (r.e.) set has an injective (one-one) recursive enumeration. Is this a standard problem that I'll find in some textbook? My approach so far: I've assumed that A is r.e. and infinite. So ... 29 Mar 2010 11:21

281 and 283: Will the twin primes always mirror the closeness between the second two primes 3 and 5?
281 and 283 are twin primes, however 283 is a strictly non-palindromic number, where as 281 is a Sophie Germain prime, the sum of the first 14 primes, the sum of 7 consecutive primes (29 + 31 + 37 + 41 + 43 + 47 + 53), a Chen prime, an Eisenstein prime with no imaginary part, and also a centered decagonal number! ... 27 Mar 2010 10:51
