We can rewrite sine of two x as two sine x cosine x. And then those two can cancel out for all x's not equaling, for all x's not equaling zero if you wanna be really mathematical precise. And so there would have been a gap there for sure on the original graph if you were to graph y equals this. But now for the limit purposes, you could say this limit is going to be the limit as x approaches zero of one over two cosine of x. And now we can go back to this green condition right over here, because we can evaluate this at x equals zero. It's gonna be one over two times cosine of zero. Cosine of zero is one.
