Nuprl Lemma : rmax-req2
∀[x,y:ℝ]. rmax(x;y) = x supposing y ≤ x
Proof
Definitions occuring in Statement :
rleq: x ≤ y
,
rmax: rmax(x;y)
,
req: x = y
,
real: ℝ
,
uimplies: b supposing a
,
uall: ∀[x:A]. B[x]
Definitions unfolded in proof :
member: t ∈ T
,
uall: ∀[x:A]. B[x]
,
uimplies: b supposing a
,
uiff: uiff(P;Q)
,
and: P ∧ Q
,
rev_uimplies: rev_uimplies(P;Q)
,
implies: P
⇒ Q
,
prop: ℙ
Latex:
\mforall{}[x,y:\mBbbR{}]. rmax(x;y) = x supposing y \mleq{} x
