The error function is defined as


A) erf(x) =0xeu2du\operatorname { erf } ( x ) = \int _ { 0 } ^ { x } e ^ { - u ^ { 2 } } d u
B) erf(x) =0eu2du\operatorname { erf } ( x ) = \int _ { 0 } ^ { \infty } e ^ { - u ^ { 2 } } d u
C) erf(x) =20xeu2du/π\operatorname { erf } ( x ) = 2 \int _ { 0 } ^ { x } e ^ { - u ^ { 2 } } d u / \pi
D) erf(x) =20eu2du/π\operatorname { erf } ( x ) = 2 \int _ { 0 } ^ { \infty } e ^ { - u ^ { 2 } } d u / \sqrt { \pi }
