∀[X:Type]. ∀[eq:EqDecider(X)]. ∀[r:CRng]. ∀[x:X]. (d1/dx = 0 ∈ PowerSeries(X;r))
Proof
Definitions occuring in Statement :
fps-deriv: df/dx,
fps-one: 1,
fps-zero: 0,
power-series: PowerSeries(X;r),
deq: EqDecider(T),
uall: ∀[x:A]. B[x],
universe: Type,
equal: s = t ∈ T,
crng: CRng
Definitions unfolded in proof :
uall: ∀[x:A]. B[x],
member: t ∈ T,
uiff: uiff(P;Q),
and: P ∧ Q,
uimplies: b supposing a,
all: ∀x:A. B[x],
fps-zero: 0,
