I just have a question on one step so hopefully I can just write that and it will make enough sense.
The only info about given anywhere is that it is some for all . It seems to make sense but I guess I'm not seeing exactly why this works. We're talking complex numbers here so this is modulus, not just absolute value but maybe it'd work the same either way.
Thanks for any help. StatisticsMan ( talk) 01:46, 4 March 2009 (UTC)
Also, why is it that some math stuff looks so crappy if it's not on a separate line or whatever? StatisticsMan ( talk) 04:13, 4 March 2009 (UTC)

OK; it was just this anyway: I write in separate lines as you like :)
Hi there refdesk!
Was wondering if anyone could give me a hand getting started on this probability question - just a hand in the right direction to get me started would be majorly appreciated! Thankyou very much in advance :)
Let k be a positive integer and let be distributed . Find a formula for . Find also a formula for .
How do I begin to tackle these problems? I'm not hugely familiar with them so any detailed(or not!)assistance would be incredibly helpful - thankyou very much again,

If k is odd, the answer is obvious. Suppose k is even.
Then remember that Γ(1/2) = √π and do some algebra, including the fact that Γ(a + 1) = aΓ(a), repeated a sufficient number of times. You should get a bunch of cancelations along the way.
I've typed hastily, so check the details in what I wrote. Michael Hardy ( talk) 17:27, 4 March 2009 (UTC)
what is the opposite of zero? —Preceding unsigned comment added by 86.144.124.55 ( talk) 17:31, 4 March 2009 (UTC)
(Unindented!) Then again, which opposite? The additive opposite of zero IS zero, whereas the multiplicative opposite is undefined, as everyone know. the boolean opposite of 0 is 1. if you want to be really pedantic, the color opposite of 0 would be a black field with a white circle, i guess.

I'm surprised the real projective line hasn't been mentioned yet... — Charles Stewart (talk) 20:23, 4 March 2009 (UTC)
The opposite of "zero" is clearly "orez", duh. :-) Dragons flight ( talk) 23:10, 4 March 2009 (UTC)
It's not true that zero is nothing because a zero comprises an amount of ink that is spread around some space. The opposite to that is everything that is not ink and not occupying any space. A black hole fits that profile nicely. (We need not wikiquibble about the ink because this is an inkless encyclopedia.) Cuddlyable3 ( talk) 23:21, 4 March 2009 (UTC)
I'm really quite amazed at all these wrong answers. The question makes no sense if "zero" is the number, but it makes perfect sense if "zero" is a predicate (as in "x is zero"). So that is the only possible meaning of the question and the answer is of course "non-zero". McKay ( talk) 09:39, 6 March 2009 (UTC)
