DERIVATIVES

Notations: Suppose y = f (x), then its derivative with respect to x, is commonly denoted by. f ′(x) = y′ = D f (x) = Dx f (x) The symbols and D are called differential operators. They are used to explicitly denote the differentiation of the function that follows. ex. Differentiate f (x) = x3 − 7x + 4. How a function can fail to be ... ................
