Theorem pmapjat2 37868

Description: The projective map of the join of an atom with a lattice element. (Contributed by NM, 12-May-2012.)

**Hypotheses**
Ref	Expression
pmapjat.b	⊢ 𝐵 = (Base‘𝐾)
pmapjat.j	⊢ ∨ = (join‘𝐾)
pmapjat.a	⊢ 𝐴 = (Atoms‘𝐾)
pmapjat.m	⊢ 𝑀 = (pmap‘𝐾)
pmapjat.p	⊢ + = (+_𝑃‘𝐾)

**Assertion**
Ref	Expression
pmapjat2	⊢ ((𝐾 ∈ HL ∧ 𝑋 ∈ 𝐵 ∧ 𝑄 ∈ 𝐴) → (𝑀‘(𝑄 ∨ 𝑋)) = ((𝑀‘𝑄) + (𝑀‘𝑋)))
