Answer 2

What's gamma function

Answer 3

if i remember correctly
\[\Gamma(x)=(x-1)! \text{ for } x\in Z^+\]

Answer 4

yeah thats right

Answer 5

it is generalization of factorial function to real numbers. actually i think complex numbers as well, so perhaps the right way to say it is "analytic continuation" but i don't want to say anything silly so perhaps a google search would be better. it is
\[\Gamma(z)=\int_0^{\infty}t^{z-1}e^{-t}dt\]

Answer 6
