Theorem log2sumbnd 27529

Description: Bound on the difference between Σ𝑛 ≤ 𝐴, log↑2(𝑛) and the equivalent integral. (Contributed by Mario Carneiro, 20-May-2016.)

**Assertion**
Ref	Expression
log2sumbnd	⊢ ((𝐴 ∈ ℝ⁺ ∧ 1 ≤ 𝐴) → (abs‘(Σ𝑛 ∈ (1...(⌊‘𝐴))((log‘𝑛)↑2) − (𝐴 · (((log‘𝐴)↑2) + (2 − (2 · (log‘𝐴))))))) ≤ (((log‘𝐴)↑2) + 2))

Distinct variable group: 𝐴,𝑛

Proof of Theorem log2sumbnd Dummy variables 𝑥 𝑦 are mutually distinct and distinct from all other variables.
