Then, we have to prove that there is a positive integer K such that for any natural number i satisfying , we have . But clearly, since K - i > 0, the inequality is equivalent to .
Siis peame tõestama, et on positiivne täisarv K selline, et iga füüsiline arv i vasta Oleme . Aga selgelt, sest K - i> 0, ebavõrdsus on samaväärne .
