Theorem pcmpt2 16853

Description: Dividing two prime count maps yields a number with all dividing primes confined to an interval. (Contributed by Mario Carneiro, 14-Mar-2014.)

**Hypotheses**
Ref	Expression
pcmpt.1	⊢ 𝐹 = (𝑛 ∈ ℕ ↦ if(𝑛 ∈ ℙ, (𝑛↑𝐴), 1))
pcmpt.2	⊢ (𝜑 → ∀𝑛 ∈ ℙ 𝐴 ∈ ℕ₀)
pcmpt.3	⊢ (𝜑 → 𝑁 ∈ ℕ)
pcmpt.4	⊢ (𝜑 → 𝑃 ∈ ℙ)
pcmpt.5	⊢ (𝑛 = 𝑃 → 𝐴 = 𝐵)
pcmpt2.6	⊢ (𝜑 → 𝑀 ∈ (ℤ_≥‘𝑁))

**Assertion**
Ref	Expression
pcmpt2	⊢ (𝜑 → (𝑃 pCnt ((seq1( · , 𝐹)‘𝑀) / (seq1( · , 𝐹)‘𝑁))) = if((𝑃 ≤ 𝑀 ∧ ¬ 𝑃 ≤ 𝑁), 𝐵, 0))
