Theorem o1fsum 14545

Description: If 𝐴(𝑘) is O(1), then Σ𝑘 ≤ 𝑥, 𝐴(𝑘) is O(𝑥). (Contributed by Mario Carneiro, 23-May-2016.)

**Hypotheses**
Ref	Expression
o1fsum.1	⊢ ((𝜑 ∧ 𝑘 ∈ ℕ) → 𝐴 ∈ 𝑉)
o1fsum.2	⊢ (𝜑 → (𝑘 ∈ ℕ ↦ 𝐴) ∈ 𝑂(1))

**Assertion**
Ref	Expression
o1fsum	⊢ (𝜑 → (𝑥 ∈ ℝ⁺ ↦ (Σ𝑘 ∈ (1...(⌊‘𝑥))𝐴 / 𝑥)) ∈ 𝑂(1))

Distinct variable groups: 𝑥,𝐴 𝑥,𝑘,𝜑 Allowed substitution hints: 𝐴(𝑘) 𝑉(𝑥,𝑘)

Proof of Theorem o1fsum Dummy variables 𝑚 𝑐 𝑛 are mutually distinct and distinct from all other variables.
