Theorem itg2add 24354

Description: The ∫₂ integral is linear. (Measurability is an essential component of this theorem; otherwise consider the characteristic function of a nonmeasurable set and its complement.) (Contributed by Mario Carneiro, 17-Aug-2014.)

Assertion

Ref	Expression
itg2add	⊢ (𝜑 → (∫2‘(𝐹 ∘f + 𝐺)) = ((∫2‘𝐹) + (∫2‘𝐺)))

Proof of Theorem itg2add

Dummy variables 𝑓 𝑔 𝑛 𝑥 are mutually distinct and distinct from all other variables.
