Theorem dochcl 42108

Description: Closure of subspace orthocomplement for DVecH vector space. (Contributed by NM, 9-Mar-2014.)

**Hypotheses**
Ref	Expression
dochcl.h	⊢ 𝐻 = (LHyp‘𝐾)
dochcl.i	⊢ 𝐼 = ((DIsoH‘𝐾)‘𝑊)
dochcl.u	⊢ 𝑈 = ((DVecH‘𝐾)‘𝑊)
dochcl.v	⊢ 𝑉 = (Base‘𝑈)
dochcl.o	⊢ ⊥ = ((ocH‘𝐾)‘𝑊)

**Assertion**
Ref	Expression
dochcl	⊢ (((𝐾 ∈ HL ∧ 𝑊 ∈ 𝐻) ∧ 𝑋 ⊆ 𝑉) → ( ⊥ ‘𝑋) ∈ ran 𝐼)

Proof of Theorem dochcl Dummy variable 𝑦 is distinct from all other variables.
