Problem 3.1. For a triangle T, let r(T) denote the ratio of the length of the longest side of T to the length of the smallest side of T. Let A denote the set of all triangles and let P(T1, T2) : 1( T2) > r(T1 ). be an open sentence where the domain of both T, and T2 is A. (a) Express the following quantified statement in words: 3TI E A, VT2 E A, P(T1, T2). (*) (b) Express the negation of the quantified statement in (*) in symbols. (c) Express the negation of the quantified statement in (*) in words. Problem 3.2. (a) Let x E R. Prove that if 0
