If 2f xy f x y

WebConsider f (xy)−f (x). Differentiating with respect to x yields yf ′(xy)− f ′(x) = xyy − x1 = 0, meaning that f (xy)− f (x) = C, where C is a constant. Plug in x = 1, f (y)−f (1) = C and ... WebIf X and Y are independent random variables, then E[XY] = E[X] E[Y]. Proof Theorem 5.1.2 can be used to show that two random variables are not independent: if E[XY] ≠ E[X] E[Y], then X and Y cannot be independent. However, beware using Theorem 5.1.2 to show that random variables are independent.
