Nuprl Lemma : implies-rsqrt-is-one
∀[x:ℝ]. rsqrt(x) = r1 supposing x = r1
Proof
Definitions occuring in Statement :
rsqrt: rsqrt(x),
req: x = y,
int-to-real: r(n),
real: ℝ,
uimplies: b supposing a,
uall: ∀[x:A]. B[x],
natural_number: $n
Definitions unfolded in proof :
uall: ∀[x:A]. B[x],
member: t ∈ T,
uiff: uiff(P;Q),
and: P ∧ Q,
uimplies: b supposing a,
prop: ℙ,
subtype_rel: A ⊆r B,
implies: P ⇒ Q
Latex:
