The LaTeX DLMF and DRMF macro \qSinKLS represents a ${\displaystyle{\displaystyle q}}$-analogue of the ${\displaystyle{\displaystyle\sin}}$ function: ${\displaystyle{\displaystyle\mathrm{Sin}_{q}}}$.

This macro is in the category of real or complex valued functions.

In math mode, this macro can be called in the following ways:

\qSinKLS{q} produces ${\displaystyle{\displaystyle{\displaystyle\mathrm{Sin}_{q}}}}$

\qSinKLS{q}@{z} produces ${\displaystyle{\displaystyle{\displaystyle\mathrm{Sin}_{q}\!\left(z\right)}}}$

\qSinKLS{q}@@{z} produces ${\displaystyle{\displaystyle{\displaystyle\mathrm{Sin}_{q}z}}}$

These are defined by ${\displaystyle{\displaystyle{\displaystyle\mathrm{Sin}_{q}\!\left(z\right):=\frac{\mathrm{E}_{q}\!\left(\mathrm{i}z\right)-\mathrm{E}_{q}\!\left(-\mathrm{i}z\right)}{2\mathrm{i}}=\sum_{n=0}^{\infty}\frac{(-1)^{n}q^{\binomial{2n+1}{2}}z^{2n+1}}{\left(q;q\right)_{2n+1}}}}}$
