Error function

Rare card · No. 63530

In mathematics, the error function (also called the Gauss error function), often denoted by e r f {\displaystyle \mathbf {erf} } , is the function erf ⁡ ( z ) = 2 π ∫ 0 z e − t 2 d t . {\displaystyle \operatorname {erf} (z)={\frac {2}{\sqrt {\pi }}}\int _{0}^{z}e^{-t^{2}}\,dt.} The integral here is a complex contour integral which is path-independent because exp ⁡ ( − t 2...
