# Integrate Complementary Error Function

## Contents

Practice online or make a printable study sheet. The error function and its approximations can be used to estimate results that hold with high probability. Washington, DC: Hemisphere, pp.385-393, 1987. For iterative calculation of the above series, the following alternative formulation may be useful: erf ⁡ ( z ) = 2 π ∑ n = 0 ∞ ( z ∏ k

At the real axis, erf(z) approaches unity at z→+∞ and −1 at z→−∞. A complex generalization of is defined as (39) (40) Integral representations valid only in the upper half-plane are given by (41) (42) SEE ALSO: Dawson's Integral, Erfc, Erfi, Fresnel Integrals, Gaussian A simple integral involving erf that Wolfram Language cannot do is given by (30) (M.R.D'Orsogna, pers.
