# Definition talk:Sine Integral Function

Perhaps a theorem page that there is no solution in terms of elementary functions to $\displaystyle \int \frac {\sin x}{x}\mathrm dx$, and a definition page to the creation of a function defined as the solution? Though I have no idea how to prove that a particular integral is unsolvable. --GFauxPas 03:50, 1 January 2012 (CST)
