WebDec 23, 2024 · In mathematics, derivatives calculate the change rate for functions as they pertain to defined variables. Explore the steps for finding the derivative of 1/cos(x), work … WebThere are really two ways of writing. If 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
