q-Factorial
The q-Analog of the Factorial (by analogy with the q-Gamma Function). For 
an integer, the 
-factorial is defined by
A reflection formula analogous to the Gamma Function reflection formula is given by
where
is the q-Cosine, 
is the q-Sine, and
is q-Pi.See also q-Beta Function, q-Cosine, q-Gamma Function, q-Pi, q-Sine
