Theorem pntrmax 27541

Description: There is a bound on the residual valid for all 𝑥. (Contributed by Mario Carneiro, 9-Apr-2016.)

**Hypothesis**
Ref	Expression
pntrval.r	⊢ 𝑅 = (𝑎 ∈ ℝ⁺ ↦ ((ψ‘𝑎) − 𝑎))

**Assertion**
Ref	Expression
pntrmax	⊢ ∃𝑐 ∈ ℝ⁺ ∀𝑥 ∈ ℝ⁺ (abs‘((𝑅‘𝑥) / 𝑥)) ≤ 𝑐

Distinct variable groups: 𝑥,𝑎 𝑥,𝑐,𝑅 Allowed substitution hint: 𝑅(𝑎)

Proof of Theorem pntrmax Dummy variable 𝑦 is distinct from all other variables.
