Prove that if i 0 then r/i ∼ r

WebbQuestion: 1 Logic 1. (a) Use a truth table to show the following are logically equivalent P ⇒ (Q ∨ R); (P ∧ ∼ Q) ⇒ R; (P ∧ ∼ R) ⇒ Q. (b) Use these results to state “If n is prime, then n is odd or n = 2” in two ways. 2. (a) Show that P ∨ ∼ (P ∧ Q) is a tautology. WebbExample: If R is any ring, the quotient ring of R by the zero ideal, namely R=0, has the same structure as R itself. Explicitly, if I = 0, then a + I = fagfor all a 2R, so the operations in R=I are exactly the same as in R itself.

So q 0= q, and hence also r = r . Lemma 3.3 Let a,b be integers with a > b > 0. Then gcd (a,b) =gcd(b,a−b). Proof

Prove that (0,1) has the same cardinality as R+ = (0,∞). Define f : (0,1) → (1,∞) by f(x) = 1 x. Note that if 0 < x < 1, then 1 x > 1. Therefore, f does map (0,1) to (1,∞). 0 1 f(x) = 1/x swaps these intervals I claim that f−1(x) = 1 x. If x > 1, then 0 < 1 x < 1, so f−1 maps (1,∞) to (0,1).
