Benford's Law I just looked up Benford's Law, and found that it describes the distribution of digits in the first decimal place. http://is.gd/dnIfL I had heard that it states that the distribution of digits is random, in all the other places. Does this other law that I thought was Benford's have a name? ... 12 Jul 2010 15:10
An exact simplification challenge - 93 (hypergeom/polylog nightmare) Hello, Overnight, I had been tortured by a nightmare. I dreamed that I was trying to simplify the following, in vain!.. -8+2/3*Pi^2-6*ln(2)^2+8*ln(2)+8*2^(1/2)+4*ln(-1+2^(1/2))- 4*ln(1+2^(1/2))+4*2^(1/2)*ln(5-2*6^(1/2))*ln(2)-4/3*2^(1/ 2)*Pi^2+6*ln(1+2^(1/2))*ln(2)-2^(1/2)*ln(-2+6^(1/2))^2+2^ (1/2)*ln(2+6^(1/... 12 Jul 2010 10:42

Partition calculation On Jul 11, 9:43 am, Bart Goddard <goddar...(a)netscape.net> wrote: Hi folks, If you can hear me through all the noise, I've got a little conundrum. Let p(n) be the number of integer partitions of integer n. Euler gave the recursion formula p(n) = sum_k (-1)^(k+1) ( p(n-k(3k-1)/2) - p(n-k(3k+1)... 14 Jul 2010 12:05

Unhappiness about product rule 1. How do you get from lim h->0 f(x + h) / h to lim h->0 f(x + h) in the second-last to last line found in my screenshot of the proof of the product rule at the bottom of http://sites.google.com/site/xtheunknown0/ maths/differentiation? 2.

Why blackbody Cosmic microwave radiation is more compelling evidence than Missing Mass Chapt 4 #220; ATOM TOTALITY There may have been in past times where I elevated the missing mass (MM) problem higher than the cosmic microwave background radiation (CMBR) because mass is more important than a feature of the cosmos of its background radiation. But the trouble with MM is that there is no science concensus as to how much is mi... 10 Jul 2010 14:55
Stupid Italiian Math 10i = 1/i. That's correct!! I am so stupid, I actually believe that if you multiply 10 by the square root of -1, the result is exactly the same as if you took 1, and divided it by the square root of -1. That's exactly how stupid I am. Also, I am so stupid that even mathforum.org does not allow me to post fr... 10 Jul 2010 14:55
non linear recurrence equations I'm serching to solve this non linear recurrence equations of this form with no hope :(. Anyone has an idea how to solve this kind of equations? a+ b X_{i-1} +c X_{i} + d X_{i+1} + e X_{i-1} X_{i+1}=0 without the last term, I can use the guassian elimination method to solve it. But when the last term appear I ... 13 Jul 2010 13:08 |
