@Mr. Wizard in fact, the documentation says: A notebook with the option setting Saveable->False can always be saved using the Save As menu item, but does not respond to Save and does not prompt for saving when it is closed.

@Mr.Wizard Mathematica doesn't prompt me to do save the file on closing but when i open this notebook, it is in fullscreen mode and with the right magnification,as desired and what do you exactly mean with "change the properties to maximized".

Selecting "Full" under Notebook Options/Windows properties/Windows size does nothing but the magnification worked well.

comment Trying to prove that $x\sin(\frac{\pi}{x})\ge\pi \cos(\frac{\pi}{x})$ for $x\ge 1$
@Jens thank you very much, Mathematica seems a tricky tool for proving theorems.

@Jens You are the only one that understood me. Your approach is good but not fully correct since Tan[Pi/x]>=Pi/x is not true for all x > 1. I tried Resolve[ForAll[x, x > 1 && (0 < x < \[Pi]/2 \[Implies] Tan[x] > x), f'[x] >= 0] ] but didn't work. Maybe i'm asking too much from Mathematica. Can you make this work please?

This is indeed a neat solution to my problem, but my question wasn't too clear, i edited it.

comment FindInstance with a Diophantine equation seems to go on forever
Mathematica seems to pick the wrong approach, i tried replacing 2012^n with other values and in most of them i ran out of memory, even if the number is very small like 864
