Hello every one,(adsbygoogle = window.adsbygoogle || []).push({});

I was doing my research and then I simply struck at a point.

The point is that i do not know how to solve the following Integral. I am not at all bad at doing math but some times I got blanked.

so, here is the Integral,

Integral (infinity,u) exponent^(-u) du

result with derivation or with some reference will be highly appreciated.

thanks
