# Inequalities Concerning Primes [closed]

I recently read a very good inequality concerning the no of primes $\pi(x)$:

$$\pi(n)>\frac{1}{6}\frac{n}{\log n}\mathrm{\ for\ }n\ge 2$$

Are any other such elementary inequalities concerning the primes?

Could you just chop those blanks in page 2? –  KennyTM Aug 10 '10 at 9:26

@Chandru1: I've edited the question to remove the scans of the text, since you didn't give any indication of where it came from (with a citation, that kind of quoting might be okay), and to change the question to ask what you said you wanted to know in your comment on lhf's answer. If you don't agree with my edits, please feel free to re-edit the question. –  Isaac Aug 10 '10 at 16:41
This is a valid question –  Casebash Aug 14 '10 at 6:39
