  • $\begingroup$ These are known as asymptotic notation, and probably explained in your textbook. $\endgroup$ – Yuval Filmus Sep 5 '13 at 11:07

    $\begingroup$ This question is too broad. You aren't asking a question about a specific problem here, but looking for a basic presentation of the subjcet. There are already plenty of such presentations on the internet and in textbooks. Please ask here if you have a specific question: some specific part of the explanations that you don't understand, or a specific problem that you face when trying to apply these notions to a particular case. $\endgroup$ – Gilles 'SO- stop being evil' Sep 5 '13 at 11:11
