I will thumbs up! thanks

72. (a) Use integration by parts to show that
S S(x) dx = xf(x) – f xf(x) dx
%3D
(b) If f and g are inverse functions and f' is continuous,
prove that
) dx = bf(b) – af (a) – S g(v) dy
%3D
Jf (a)
[Hint: Use part (a) and make the substitution y = f(x).]
(c) In the case where f and g are positive functions and
b > a > 0, draw a diagram to give a geometric interpre-
tation of part (b).
(d) Use part (b) to evaluate In x dx.
