Answer 7

looks like the statistics "error" function

Answer 8

in fact if you divide by \[2\pi\] you get the normal curve exactly. that is because
\[\int_{-\infty}^{\infty}e^{-x^2}dx=2\pi\] and so
\[\frac{1}{2\pi}\int_{-\infty}^{\infty}e^{-x^2}dx=1\]

Answer 9

still not sure what "is" is though...
