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. Now, its input is w of u of x. We already figured out w of u of x is going to be this business. So it's going to be sine of x plus one.
