${\displaystyle{\displaystyle{\displaystyle\mathcal{D}_{q}\left[w(x;q)S_{n}\!\left(x;q\right)\right]=\frac{1-q^{n+1}}{1-q}q^{-1}w(q^{-1}x;q)S_{n+1}\!\left(q^{-1}x;q\right)}}}$

Substitution(s)

${\displaystyle{\displaystyle{\displaystyle w(x;q)=\frac{1}{\left(-x,-qx^{-1};q\right)_{\infty}}}}}$ &
${\displaystyle{\displaystyle{\displaystyle w(x)=\frac{\gamma}{\sqrt{\pi}}\exp\left(-\gamma^{2}{\ln^{2}}x\right),\quad x>0,\quad\textrm{with}\quad\gamma^{2}=-\frac{1}{2\ln q}=\frac{\gamma}{\sqrt{\pi}}x^{-\frac{1}{2}}\exp\left(-\gamma^{2}{\ln^{2}}x\right),x>0{\rm with}\gamma^{2}}}}$
