Theorem iunocv 19844
 Description: The orthocomplement of an indexed union. (Contributed by Mario Carneiro, 23-Oct-2015.)
Hypotheses
Ref Expression
inocv.o = (ocv‘𝑊)
iunocv.v 𝑉 = (Base‘𝑊)
Assertion
Ref Expression
iunocv ( 𝑥𝐴 𝐵) = (𝑉 𝑥𝐴 ( 𝐵))
Distinct variable groups:   𝑥,𝑉   𝑥,𝑊
Allowed substitution hints:   𝐴(𝑥)   𝐵(𝑥)   (𝑥)

Proof of Theorem iunocv
Dummy variables 𝑦 𝑧 are mutually distinct and distinct from all other variables.
