# An ordinary generating function for the Stirling numbers of the second kind

I'm currently struggling with ordinary generating functions(OGF) and was hoping somebody could point me in the direction of determining the OGF for the Stirling numbers of the second kind $\sum_{n=k}^\infty S(n,k) x^n$.

• That's a perfect link for the OGF but I'm having problems with proving that it's the OGf not just what the OGF is. – Atom May 5 '13 at 16:48
