#include <boost/math/special_functions/jacobi_elliptic.hpp>
namespace boost { namespace math { template <class T, class U> calculated-result-type jacobi_dn(T k, U u); template <class T, class U, class Policy> calculated-result-type jacobi_dn(T k, U u, const Policy& pol); }} // namespaces
This function returns the Jacobi elliptic function dn.
The final Policy argument is optional and can be used to control the behaviour of the function: how it handles errors, what level of precision to use etc. Refer to the policy documentation for more details.
This function is a trivial wrapper around jacobi_elliptic.
