floating-point-type ellint_2(floating-point-type k, floating-point-type phi); float ellint_2f(float k, float phi); long double ellint_2l(long double k, long double phi);
Effects: These functions compute the incomplete elliptic integral of the second kind of their respective argumentsk and phi (phi measured in radians).
Returns: E(k, Ï), where E is given by Formula 29.33,k is k, andÏ is phi.
E(k,Ï)=â«Ï0â1âk2sin2θdθ , for |k|â¤1(29.33)
