    Calculating exponential integral

    Hi,

    I have problem calculating the integral of e^(-x)^(Beta) from 0 to infinity. Anyone who knows how?

    There is no elementary solution. We need the gamma function.

    \beta  > 0,\quad \int_0^\infty  {e^{ - x^\beta  } }  = \Gamma \left( {\frac{1}{\beta } + 1} \right)
