Abstract : In this paper, we rederive the identity $\Gamma_q(x)\Gamma_q(1- x) =\frac { \pi_q }{ \sin_q (\pi_q x ) }$. Then, we give $q$-analogue of Gauss' multiplication formula and study representation of $q$-oscillator algebra in terms of the $q$-factorial polynomials.
Keywords : $q$-gamma function, $q$-polygamma function
