Theorem qlax2i

Description: One of the equations showing CH is an ortholattice. (This corresponds to axiom "ax-2" in the Quantum Logic Explorer.) (Contributed by NM, 4-Aug-2004) (New usage is discouraged.)

Ref Expression
Hypotheses qlax.1 ⊢ 𝐴 ∈ Cℋ
qlax.2 ⊢ 𝐵 ∈ Cℋ
Assertion qlax2i ( 𝐴 ∨ℋ 𝐵 ) = ( 𝐵 ∨ℋ 𝐴 )

Proof

Step Hyp Ref Expression
1 qlax.1 ⊢ 𝐴 ∈ Cℋ
2 qlax.2 ⊢ 𝐵 ∈ Cℋ
3 1 2 chjcomi ⊢ ( 𝐴 ∨ℋ 𝐵 ) = ( 𝐵 ∨ℋ 𝐴 )
