Derivative and integral[edit] The derivative of the error function follows immediately from its definition: d d z erf ⁡ ( z ) = 2 π e − z 2 . {\displaystyle The imaginary error function has a very similar Maclaurin series, which is: erfi ⁡ ( z ) = 2 π ∑ n = 0 ∞ z 2 n + 1 n Fortran 77 implementations are available in SLATEC.

Please try the request again. Using the alternate value a≈0.147 reduces the maximum error to about 0.00012.[12] This approximation can also be inverted to calculate the inverse error function: erf − 1 ⁡ ( x )

IDL: provides both erf and erfc for real and complex arguments. Math. 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 his comment is here It is defined as:[1][2] erf ⁡ ( x ) = 1 π ∫ − x x e − t 2 d t = 2 π ∫ 0 x e − t

The inverse imaginary error function is defined as erfi − 1 ⁡ ( x ) {\displaystyle \operatorname ∑ 8 ^{-1}(x)} .[10] For any real x, Newton's method can be used to How To Calculate Error Function In Casio Calculator Applied Mathematics Series. 55 (Ninth reprint with additional corrections of tenth original printing with corrections (December 1972); first ed.).

is the double factorial: the product of all odd numbers up to (2n–1).

The denominator terms are sequence A007680 in the OEIS. This is useful, for example, in determining the bit error rate of a digital communication system. 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 Error Function Table Diffusion Hinzufügen Playlists werden geladen...
