Nuprl Lemma : arcsine0
arcsine(r0) = r0
Proof
Definitions occuring in Statement :
arcsine: arcsine(x),
req: x = y,
int-to-real: r(n),
natural_number: $n
Definitions unfolded in proof :
arcsine: arcsine(x),
all: ∀x:A. B[x],
member: t ∈ T,
uall: ∀[x:A]. B[x],
so_lambda: λ2x.t[x],
top: Top,
so_apply: x[s],
and: P ∧ Q,
cand: A c∧ B,
iff: P ⇐⇒ Q,
rev_implies: P ⇐ Q,
implies: P ⇒ Q,
less_than: a < b,
squash: ↓T,
less_than': less_than'(a;b),
true: True,
prop: ℙ,
rfun: I ⟶ℝ,
uimplies: b supposing a,
uiff: uiff(P;Q),
rev_uimplies: rev_uimplies(P;Q)
