# Math Help - Summation to infinity involving gamma

1. ## Summation to infinity involving gamma

How do I solve this :

1+(gamma)+ (gamma^2)/(2!)+(gamma^3)/3!+....

Btw,how do I post questions using mathematical symbols(gamma,set notation etc.)? I'm new here. Thanks a lot!

2. The Maclaurin series for $f(x) = e^x$ is $\sum_{n=0}^{\infty} \frac{x^n}{n!}$.

We know the series converges to $f(x)$, so your question amounts to recognizing that your series is simply $f(\gamma)$
