Theorem ip1i

Description: Equation 6.47 of Ponnusamy p. 362. (Contributed by NM, 27-Apr-2007) (New usage is discouraged.)

Ref Expression
Hypotheses ip1i.1 ⊢ 𝑋 = ( BaseSet ‘ 𝑈 )
ip1i.2 ⊢ 𝐺 = ( +𝑣 ‘ 𝑈 )
ip1i.4 ⊢ 𝑆 = ( ·𝑠OLD ‘ 𝑈 )
ip1i.7 ⊢ 𝑃 = ( ·𝑖OLD ‘ 𝑈 )
ip1i.9 ⊢ 𝑈 ∈ CPreHilOLD
ip1i.a ⊢ 𝐴 ∈ 𝑋
ip1i.b ⊢ 𝐵 ∈ 𝑋
ip1i.c ⊢ 𝐶 ∈ 𝑋
Assertion ip1i ( ( ( 𝐴 𝐺 𝐵 ) 𝑃 𝐶 ) + ( ( 𝐴 𝐺 ( - 1 𝑆 𝐵 ) ) 𝑃 𝐶 ) ) = ( 2 · ( 𝐴 𝑃 𝐶 ) )
