How do I solve this :
1+(gamma)+ (gamma^2)/(2!)+(gamma^3)/3!+....
The answer given is e^gamma.
Btw,how do I post questions using mathematical symbols(gamma,set notation etc.)? I'm new here. Thanks a lot!
The Maclaurin series for $\displaystyle f(x) = e^x$ is $\displaystyle \sum_{n=0}^{\infty} \frac{x^n}{n!}$.
We know the series converges to $\displaystyle f(x)$, so your question amounts to recognizing that your series is simply $\displaystyle f(\gamma)$
