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 N ! ∫ x ∞ t − 2 N e − t 2 d t , {\displaystyle R_ − 7(x):={\frac {(-1)^ − 6}{\sqrt {\pi }}}2^ − 5{\frac {(2N)!} − 4}\int _ 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 Mitt kontoSökMapsYouTubePlayNyheterGmailDriveKalenderGoogle+ÖversättFotonMerWalletDokumentBloggerKontakterHangoutsÄnnu mer från GoogleLogga inDolda fältSök efter grupper eller meddelanden För att kunna använda diskussioner i Google Grupper måste du aktivera JavaScript i webbläsarinställningarna och sedan uppdatera sidan. . https://support.office.com/en-us/article/ERF-function-c53c7e7b-5482-4b6c-883e-56df3c9af349

The inverse error function is usually defined with domain (−1,1), and it is restricted to this domain in many computer algebra systems.
