WCelli3() Function WCelli3 ( N As  Double, K As  Double  ) Complete elliptic integral of the third kind P(n, k) Purpose WCelli3 computes the Legendre form of complete elliptic integral of the third kind P(n, k). P(n, k) = P(π/2, n, k) where P(φ, n, k) is the incomplete elliptic integral of the third kind defined as follows: P(φ, n, k) = ∫ 1/((1 - n(sin(t))^2)sqrt(1 - k^2(sin(t))^2)) dt [0, φ] Returns Complete elliptic integral of the third kind P(n, k). Parameters [in] N Argument n. (N < 1) [in] K Argument k. (-1 < K < 1) Reference boost/math/special_functions
