WElli2() Function WElli2 ( Phi As  Double, K As  Double  ) Incomplete elliptic integral of the second kind E(φ, k) Purpose WElli2 computes the Legendre form of incomplete elliptic integral of the second kind E(φ, k). E(φ, k) = ∫ sqrt(1 - k^2(sin(t))^2) dt [0, φ] Returns Incomplete elliptic integral of the second kind E(φ, k). Parameters [in] Phi Argument φ [rad]. [in] K Argument k (K^2*sin(Phi)^2 <= 1 (|K| <= 1 if |Phi| > π/2)) Reference boost/math/special_functions
