Let f be analytic and bounded by M in z≤ r. Prove that f (n)(z) ≤ n!M/〖(rz)〗^n for (z < r).

I can't decipher your question.

Also in my opinion and speaking only for myself, questions at this level should certainly be $\LaTeX$'d. If you can hack complex variables you can certainly hack $\LaTeX$ Last edited by Maschke; February 27th, 2017 at 04:03 PM.

ps  I hope I didn't frighten off the OP. It's ok if you don't use math markup. But what you wrote is not correct as given.
