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. In this special case, the ...I received this question from my mathematics professor as a leisure-time logic quiz, and although I thought I answered it right, he denied.
