So that's sine of x plus one. And then if we define a third function, let's say, let's see, I'll call it, let's call it h. I'm running out of variables. Well, there are a lot of letters left. So if I say h of x is just equal to the cosine of whatever I input, so it's equal to the cosine of x, well then h of w of u of x is gonna be g of x. Let me write that down. H of w of u of x, u of x, is going to be equal to, remember, h of x takes the cosine of whatever its input is. So it's gonna take the cosine.
