Theorem dochval2 42107

Description: Subspace orthocomplement for DVecH vector space. (Contributed by NM, 14-Apr-2014.)

**Hypotheses**
Ref	Expression
dochval2.o	⊢ ⊥ = (oc‘𝐾)
dochval2.h	⊢ 𝐻 = (LHyp‘𝐾)
dochval2.i	⊢ 𝐼 = ((DIsoH‘𝐾)‘𝑊)
dochval2.u	⊢ 𝑈 = ((DVecH‘𝐾)‘𝑊)
dochval2.v	⊢ 𝑉 = (Base‘𝑈)
dochval2.n	⊢ 𝑁 = ((ocH‘𝐾)‘𝑊)

**Assertion**
Ref	Expression
dochval2	⊢ (((𝐾 ∈ HL ∧ 𝑊 ∈ 𝐻) ∧ 𝑋 ⊆ 𝑉) → (𝑁‘𝑋) = (𝐼‘( ⊥ ‘(^◡𝐼‘∩ {𝑧 ∈ ran 𝐼 ∣ 𝑋 ⊆ 𝑧}))))

Distinct variable groups: 𝑧,𝐻 𝑧,𝐼 𝑧,𝐾 𝑧,𝑉 𝑧,𝑊 𝑧,𝑋 Allowed substitution hints: 𝑈(𝑧) 𝑁(𝑧) ⊥ (𝑧)

Proof of Theorem dochval2 Dummy variable 𝑥 is distinct from all other variables.
