Example 7.2.5. The relation T on R ∗ is defined as aTb ⇔ a b ∈ Q. Since a a = 1 ∈ Q, the relation T is reflexive; it follows that T is not irreflexive. The relation T is symmetric, because if a b can be written as m n for some integers m and n, then so is its reciprocal b a, because b a = n m.Discuss. Courses.

We can use indirect proofs to prove an implication. There are two kinds of indirect proofs: proof by contrapositive and proof by contradiction.
