[tex]\sum_{p\leq N}\frac{1}{p}=\log\log N + A + O(\frac{1}{\log N})[/tex](adsbygoogle = window.adsbygoogle || []).push({});

Does it mean that we can simply replace the O part with a function that is a constant times 1/(log N)? What would be the difference between [tex] A + O(\frac{1}{\log N})[/tex] and [tex]O(1)[/tex]?
