Prove that the following two statements are not logically equivalent. In your proof, completely justify your answer.

(a) A real number is less than 1 only if its reciprocal is greater than 1.

(b) Having a reciprocal greater than 1 is a sufficient condition for a real number to be less than 1.

Proof:

#2.

Prove that the following is a valid argument:

All real numbers have nonnegative squares.

The number i has a negative square.

         Therefore, the number i is not a real number.

Proof:

Determine whether the statements in (a) and (b) are logically equivalent. Bob is both a math and computer science major and Ann is a math major, but Ann is not both a math and computer science major. It is not the case that both Bob and Ann are both math and computer science majors, but it is the case that Ann is a math major and Bob is both a math and computer science major.

49. Which of the following is the most logically sound proof in favour of God’s existence? (A) \Every society throughout human history has had some notion of God, and there-fore God must exist." (B) \I feel God’s existence through the Holy Spirit, and therefore know that He exists." (C) \Everything that begins to exist has a cause. The universe began to exist. There-fore, the universe has a cause, which I call God." (D) \It is ridiculously unlikely that the universe...

Prove the following using the method suggested: (a) Prove the following either by direct proof or by contraposition: Let a ∈ Z, if a ≡ 3 (mod 5) and b ≡ 2 (mod 5), then ab ≡ 1 (mod 5). (b) Prove the following by contradiction: Suppose a, b ∈ Z. If a² + b² is odd, then (2|a) ⊕ (2|b), where ⊕ is the exclusive disjuntion, i.e. p ⊕ q = (p ∨ q) ∧ ¬(p ∧ q). (d)...

Prove that the following statements are equivalent. A. The Euclidean parallel postulate holds. B. Given any triangle △ABC and given any segment DE, there exists a triangle △DEF having DE as one of its sides such that △ABC ∼ △DEF (Wallis’ postulate on the existance of similar triangles). (you cannot use measures)

prove the following statement: If the augmented matrices of two linear systems are row equivalent, then those systems are equivalent. (To do this, start with a solution to one of the systems and show that it is still a solution of the other system under each of the three elementary row operations.)
