WCelli2() Function WCelli2 ( K As  Double ) Complete elliptic integral of the second kind E(k) Purpose WCelli2 computes the Legendre form of complete elliptic integral of the second kind E(k). E(k) = E(π/2, k) where E(φ, k) is the incomplete elliptic integral of the second kind defined as follows: E(φ, k) = ∫ sqrt(1 - k^2(sin(t))^2) dt [0, φ] Returns Complete elliptic integral of the second kind E(k). Parameters [in] K Argument k. (-1 <= K <= 1) Reference boost/math/special_functions
