So I'll take the first sine of x. So I'll do, I'll take this one right over here and put it over this x. So sine of x over x times the second sine of x, let's say this one, over one plus cosine of x. Times sine of x over one plus cosine of x. All I've done is I've leveraged a trigonometric identity and I've done a little bit of algebraic manipulation. Well here, the limit of the product of these two expressions is going to be the same thing as the product of the limits. So I can rewrite this as being equal to the limit as x approaches zero of sine of x over x times the limit as x approaches zero of sine of x over one plus cosine of x.
