Let  > 0. Prove that log x  x  for x large. Prove that there exists a
constant C such that log x  Cx  for all x 2 [1, 1 ), C ! 1 as  ! 0+,
and C ! 0 as  ! 1 Please justify all steps and be rigorous because it is an analysis problem.
(Note: The problem falls under the chapter on Differentiability on R in
the section entitled The Mean Value Theorem, and the hint says: Find the
maximum of f(x) = log x/x  forx 2 [1, 1 ))
