the volume of the corner of the N-dimension cube is:

V=( sqrt(N) * h )^N / N!

where h is the height of the corner.

h = a /sqrt(N) where a is the edge of the corner.

The geometrical method is not equivalent to JFF's problem for N>3 - 008 (532 bytes) 2008-12-17, 17:11:56 (284950)
- JFF's question was a=(N+1)/2, a is always >1; I don't see why "a>1 means - chouqilozi (58 bytes) 2008-12-18, 08:37:13 (285115)

请把　h, a and V在原问题中对应的变量再详细解释一下。 (无内容) - JFF (0 bytes) 2008-12-17, 16:50:40 (284948)
