sn( z, m )

The Jacobi elliptic sine function of z and parameter m in Math. Defined as the sine of the Jacobi amplitude:

\[ \operatorname{sn}( u | m ) = \sin [ \operatorname{am}( u | m ) ] \]

Note that all Jacobi elliptic functions in Math use the parameter rather than the elliptic modulus k, which is related to the parameter by \( m = k^2 \).
