And so the mean of the X-measured variation is distinct from the variation of the X-measured mean. Though they sum to the total variation by no coincidence. E(Var(Y ∣ X)) = = …3 Answers. First consider the simplest case where a(x) = a a ( x) = a and b(x) = b b ( x) = b for all x x. Then the Leibniz formula becomes. d dx(∫b a f(x, t)dt) =∫b a ∂ ∂xf(x, t)dx d d x ( ∫ a b f ( x, t) d t) = ∫ a b ∂ ∂ x f ( x, t) d x. i.e. it is reduced to moving the derivative inside the integral.

Munkres Analysis on Manifolds. It might be a good idea to say something about the connection between the axiom of choice and the Banach-Tarski paradox.
