The correct question is, Why (or when) is it useful to view [math]\cos^2(x)[/math] as a composite function? In calculus, it is useful when taking the derivative of [math]f(x) = \cos^2 x[/math] to recognize that [math]f(x)[/math] is a composition of two functions whose derivatives we (presumably) already know.
