The following is from another forum and an email I got. I was hoping that somebody within this group might assist the person requesting help. ----------------------------------------------------------------- From: alauzara <angelgalicia30@hotmail.com> Date: February 02, 2009, 17:12:37 Subject: Help with Fractint Hello, everybody! I have a problem that maybe somebody can help me. How would be a formula for Fractint, where the increment is equal to ln(x)? That I basically would like to find is related to the Prime Number Theory, which says that the distribution of prime numbers in the natural numbers, called pi(x), is equal to x / ln x, where x is the natural number, so long as x is big enough. I'm trying to find if this distribution is fractal, and get the right parameters to use fractinct and get the correspondent formulae from you guys. Anyway, thanks again for your interest, I'm looking forward to see if you can help me on this inquiry.
