Theorem irrapxlem1 43664

Description: Lemma for irrapx1 43670. Divides the unit interval into 𝐵 half-open sections and using the pigeonhole principle fphpdo 43659 finds two multiples of 𝐴 in the same section mod 1. (Contributed by Stefan O'Rear, 12-Sep-2014.)

**Assertion**
Ref	Expression
irrapxlem1	⊢ ((𝐴 ∈ ℝ⁺ ∧ 𝐵 ∈ ℕ) → ∃𝑥 ∈ (0...𝐵)∃𝑦 ∈ (0...𝐵)(𝑥 < 𝑦 ∧ (⌊‘(𝐵 · ((𝐴 · 𝑥) mod 1))) = (⌊‘(𝐵 · ((𝐴 · 𝑦) mod 1)))))

Distinct variable groups: 𝑥,𝐴,𝑦 𝑥,𝐵,𝑦

Proof of Theorem irrapxlem1 Dummy variable 𝑎 is distinct from all other variables.
