28.7 Mathematical functions for floating-point types [c.math]

28.7.6 Mathematical special functions [sf.cmath] Incomplete elliptic integral of the third kind [sf.cmath.ellint.3]

floating-point-type ellint_3(floating-point-type k, floating-point-type nu, floating-point-type phi); float ellint_3f(float k, float nu, float phi); long double ellint_3l(long double k, long double nu, long double phi);
Effects: These functions compute the incomplete elliptic integral of the third kind of their respective arguments k, nu, and phi (phi measured in radians).
where ν is nu, k is k, and φ is phi.
