You're asked to find lim x-->0 sin7x / 4x(adsbygoogle = window.adsbygoogle || []).push({});

The part of this example that I don't understand the most is how they get 1 out of sin7x/7x when x-->0.

[edit]

Sorry about the ridiculously small image. The dimension restrictions are ridiculous, and I didn't notice that the image didn't attach properly the first time.
