Nuprl Lemma : rseteq_weakening
∀[A,B:Set(ℝ)].  rseteq(A;B) supposing A = B ∈ Set(ℝ)
Proof
Definitions occuring in Statement : 
rseteq: rseteq(A;B), 
rset: Set(ℝ), 
uimplies: b supposing a, 
uall: ∀[x:A]. B[x], 
equal: s = t ∈ T
Definitions unfolded in proof : 
rseteq: rseteq(A;B), 
uall: ∀[x:A]. B[x], 
uimplies: b supposing a, 
member: t ∈ T, 
all: ∀x:A. B[x], 
iff: P ⇐⇒ Q, 
and: P ∧ Q, 
implies: P ⇒ Q, 
prop: ℙ, 
rev_implies: P ⇐ Q
Latex:
\mforall{}[A,B:Set(\mBbbR{})].    rseteq(A;B)  supposing  A  =  B
