The imaginary error function has a very similar Maclaurin series, which is: erfi ( z ) = 2 π ∑ n = 0 ∞ z 2 n + 1 n W. Laplace (1812) derived an asymptotic expansion of the error function.

To use these approximations for negative x, use the fact that erf(x) is an odd function, so erf(x)=−erf(−x).

For large enough values of x, only the first few terms of this asymptotic expansion are needed to obtain a good approximation of erfc(x) (while for not too large values of navigate here Learn more about a JSTOR subscription Have access through a MyJSTOR account?

For example, they can be represented through the confluent hypergeometric functions and : Representations of the probability integrals , , , and through classical Meijer G functions are rather simple: The The inverse was systematically investigated in the second half of the twentieth century, especially by J. Laplace (1774) where it was expressed through the following integral: Later C. Check This Out Note: In calculating the moving wall, the current year is not counted.

I tried to use some approximations of inverse error functions, such as $$ \text{erf}^{-1}(x) = \sum_{k=0}^{N} \frac{c_k}{2k+1}\left(\frac{\sqrt \pi}{2}x\right)^{2k+1}, (2)$$ to finite $N$ (from http://en.wikipedia.org/wiki/Error_function#Inverse_functions) which holds if $x \in [-1,1]$ and Error Function Matlab The denominator terms are sequence A007680 in the OEIS. Periodicity The probability integrals , , , and , and their inverses , , and do not have periodicity.

After division by n!, all the En for odd n look similar (but not identical) to each other. http://toriisoft.com/error-function/inverse-error-function-in-excel.html When the error function is evaluated for arbitrary complex arguments z, the resulting complex error function is usually discussed in scaled form as the Faddeeva function: w ( z ) =
