So let's see if we can work this out. So the first thing we're going to do is algebraically manipulate this expression a little bit. What I'm going to do is I'm gonna multiply both the numerator and the denominator by one plus cosine of x. So times the denominator, I have to do the same thing, one plus cosine of x. I'm not changing the value of the expression. This is just multiplying it by one. But what does that do for us? Well, I can rewrite the whole thing as the limit as x approaches zero.
