LCCN65-12253. The defining integral cannot be evaluated in closed form in terms of elementary functions, but by expanding the integrand e−z2 into its Maclaurin series and integrating term by term, one obtains The integrand ƒ=exp(−z2) and ƒ=erf(z) are shown in the complex z-plane in figures 2 and 3. http://www.danielsoper.com/statcalc/calculator.aspx?id=51 Similarly, the En for even n look similar (but not identical) to each other after a simple division by n!.
