That's basically it.(adsbygoogle = window.adsbygoogle || []).push({});

My thinking is that since it's not defined at x = 0, it is not analytic (and x = 0 is therefore a singular point).

For a further look at my work, including the original context of the question, see below:

Here's my first attempt at LaTex, which I have copied and pasted from some other users!

[tex]\frac{sin(x)}{x} = \sum_{n=0}^{\infty}\frac{(-1)^{n}\(x^{2n+1})}{x(2n+1)!}=[/tex].... man, I give up. I can't get an "x" in the numerator! Whatever. Obviously I know how to write the power series...

I'll copy answers from this site to the other (or vice versa) as soon as they come in, as I am actively watching both sites. Thanks!
