Euler's Infinite Product

Click on the image for a detailed proof

\Gamma(s)=\frac{1}{s}\prod_{n=1}^{\infty}\left(1+\frac{1}{n}\right)^s\left(1+\frac{s}{n}\right)^{-1}

This expression of the Gamma Function as an Infinite Product is due to Euler; it is often used to compute the function’s logarithm.

The demonstration we propose makes use of Gauss’s Expression for the Gamma Function.
