28.7.6.7 Complete elliptic integral of the third kind [sf.cmath.comp.ellint.3]

floating-point-type comp_ellint_3(floating-point-type k, floating-point-type nu); float comp_ellint_3f(float k, float nu); long double comp_ellint_3l(long double k, long double nu);
Effects: These functions compute the complete elliptic integral of the third kind of their respective arguments k and nu.
Returns:
where k is k and ν is nu.
