NettetIf you look at the upper left of the original f (x) function, we see f (x) = cos^3 (x) = (cos x)^3. They really mean the same thing; it's just two different ways of writing the same thing. However, be careful about negative powers. For example, sin^-1 (x) is not the same as (sin x)^-1 or csc x. Comment. NettetAboutTranscript. ∫sin (x)dx=-cos (x)+C, ∫cos (x)dx=sin (x)+C, and ∫eˣdx=eˣ+C.
