Calc 3 --> iterated integrals

Let a and b be real numbers, and let h be a continuous function defined on [a, b].
(a) Change the order of integration to show that
b

h(y) dy dx
(Ь — у)h() dy.
(b) Use the integration by parts formula
b

f(x) =
h(y) dy
and g'(x) = 1
to show that
h(y) dy dx =
(Ь — у)h(у) dy.
