So I was helping this person the other day, and this problem made me pretty mad.(adsbygoogle = window.adsbygoogle || []).push({});

[tex]\lim_{x\rightarrow\frac{\pi}{9}}\left(\frac{\sin x}{x-\frac{\pi}{9}}\right)[/tex]

First, I added and subtracted pi/9. I regrouped the angle so that it was sin[(x-pi/9)+pi/9] and expanded it, but that didn't help at all.

I could use L'Hopital, but this is a calculus 1 problem.
