dn( z, m )
The Jacobi delta amplitude function of z and parameter m in Math. Defined by
\[ \operatorname{dn}( z | m ) = \sqrt{ 1 - m \operatorname{sn}^2( z| m ) } \]Note that all Jacobi elliptic functions in Math use the parameter rather than the elliptic modulus k, which is related to the parameter by \( m = k^2 \).
Real part on the real axis:
Imaginary part on the real axis is zero for real parameter.
Real part on the imaginary axis:
Imaginary part on the imaginary axis is zero for real parameter.
