Theorem dvhopspN 36404

Description: Scalar product of DVecH vector expressed as ordered pair. (Contributed by NM, 20-Nov-2013.) (New usage is discouraged.)

Hypothesis

Ref	Expression
dvhopsp.s	|- S = ( s e. E , f e. ( T X. E ) |-> <. ( s ` ( 1st ` f ) ) , ( s o. ( 2nd ` f ) ) >. )

Assertion

Ref	Expression
dvhopspN	|- ( ( R e. E /\ ( F e. T /\ U e. E ) ) -> ( R S <. F , U >. ) = <. ( R ` F ) , ( R o. U ) >. )

Distinct variable groups:   f, s, E   T, f, s

Allowed substitution hints:   R( f, s)   S( f, s)   U( f, s)   F( f, s)
