Hi. In playing around with the TI, I noticed that it gives the result
sqr(pi) for (-1/2)! In the manual, it gives a recursive definition for
factorials
which in part defines (-1/2)! in this way. I figure that this must be a
convention adopted for convenience with respect to some probability theory,
but I couldn't find it in my old probabability text books. Does anyone out
there know about this?
