The function {{\rm erf}\left(x\right)} satisfies the differential equation

\displaystyle {\frac {d^{2}}{d{x}^{2}}}y \left( x \right) +2\,x{\frac {d}{dx}}y \left( x \right) = 0

with initial values y \left( 0 \right) =0 and y' \left( 0 \right) =\frac{2}{\sqrt {\pi }}.Generated on 2020-09-28 06:25:06 using unknown version.
