An Infinite Product
Hello, consider the infinite product product_{n=1}^Infty [1 + (n^(-2))], which is easily seen to converge taking the logarithm. Someone knows th exact value of the product? Thank you very much for your attention. My Best Regards, Maury Barbato ... 13 Apr 2010 07:16

volume of ellipsoid in spherical coordinates
Is it possible to find the volume of a given ellipsoid in spherical coordinates? It seems to be complicated in terms of handling the z variable. That is, it looks like the inner integral, of a triple integral, would integrate from the lower half of the ellipsoid to the upper half. ((x-1)/a)^2 + ((y + 1)/b)^2 +... 12 Apr 2010 00:30

deriving speed of light out of just pure mathematics; 3rd attempt #590 Correcting Math
Now in this method of strip packing, the volume of the sphere need not necessarily be a packing of the log-spiral, for the meridians can be packed into the interior of a sphere. And one can imagine a "solid packing" by hoses as meridians of decreasing size to solidly pack the interior. So either the Log-spiral ... 12 Apr 2010 00:30

Representative Surfaces (For H_2(M) )Always Exist. If M is a4-manifold.
Hi, I am trying to show that for M a 4-manifold, and [a]_2 a class in H_2(M,Z) , there is always a surface that represents [a]_2 , i.e., there exists a surface S , and an embedding i of S into M , with [ioS]_2 =[a]_2. ** What I have ** If M is simply-connected, so that Pi_1(M)=0 (No... 14 Apr 2010 01:09
