Strange Calculus example

  1. Nov 3, 2004 #1
    You're asked to find lim x-->0 sin7x / 4x

    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.

    Are you familiar with [itex]\lim_{x \rightarrow 0} (sin x) / x = 1[/itex]?

    No, I was not. I guess that clears that up, thanks:p
