Recall that Etan E R is positive if the following two conditions hold: There exists N E Z+ such that an >0 for alln2 N. We use the notation R+to denote the set of positive real numbers: R+ = { E{a») R : Efe») is positive} 1. In class, we proved that the relation<on R, given by is an order relation. In this problem, you'll prove that R satisfies the axioms of an ordered field (a) If E(anh E{놔,Ep., }...
