Integral representation of the Euler-Mascheroni constant

Click on the image for a detailed proof

\gamma(s)=\int_{0}^{1}\frac{1-e^{-t}-e^{-\frac{1}{t}}}{t}\mathrm{d}t

There are several ways to express the Euler-Mascheroni constant as an integral. The one we explain today is used to prove various properties of the Gamma Function.
