Theorem brafval 22539
Description: The bra of a vector, expressed as  <. A  | in Dirac notation. See df-bra 22446. (Contributed by NM, 15-May-2006.) (Revised by Mario Carneiro, 23-Aug-2014.) (New usage is discouraged.)
Assertion
Ref Expression
brafval  |-  ( A  e.  ~H  ->  ( bra `  A )  =  ( x  e.  ~H  |->  ( x  .ih  A ) ) )
Distinct variable group:    x, A

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