Theorem hhsm

Description: The scalar product operation of Hilbert space. (Contributed by NM, 17-Nov-2007) (New usage is discouraged.)

Ref Expression
Hypothesis hhnv.1 ⊢ U = + ℎ ⋅ ℎ norm ℎ
Assertion hhsm ⊢ ⋅ ℎ = ⋅ 𝑠OLD ⁡ U

Proof

Step Hyp Ref Expression
1 hhnv.1 ⊢ U = + ℎ ⋅ ℎ norm ℎ
2 1 hhnv ⊢ U ∈ NrmCVec
3 1 2 h2hsm ⊢ ⋅ ℎ = ⋅ 𝑠OLD ⁡ U
