Weierstrass Product for the Gamma Function

LATEXis good for typesetting math. LATEXhandles the numbering for the enumerate list environment automatically. LATEX manages cross references automatically. The following formula may be found in Whittaker & Watson [4].

\int_{0}^{\infty} t^{x} e^{- t} \frac{d t}{t} = \frac{1}{x} \prod_{k = 1}^{\infty} \frac{{(1 + \frac{1}{k})}^{x}}{(1 + \frac{x}{k})}
