Nuprl Lemma : rv-ip-add2
∀[rv:InnerProductSpace]. ∀[x,y,z:Point(rv)]. (z ⋅ x + y = (z ⋅ x + z ⋅ y))
Proof
Definitions occuring in Statement :
rv-ip: x ⋅ y,
inner-product-space: InnerProductSpace,
rv-add: x + y,
req: x = y,
radd: a + b,
uall: ∀[x:A]. B[x]
Definitions unfolded in proof :
uall: ∀[x:A]. B[x],
member: t ∈ T,
subtype_rel: A ⊆r B,
implies: P ⇒ Q,
guard: {T},
uimplies: b supposing a,
uiff: uiff(P;Q),
and: P ∧ Q,
rev_uimplies: rev_uimplies(P;Q)
