∀[X:Type]. ∀[eq:EqDecider(X)]. ∀[r:CRng]. ∀[f,g:PowerSeries(X;r)]. ∀[x:X].
(d(f+g)/dx = (df/dx+dg/dx) ∈ PowerSeries(X;r))
Proof
Definitions occuring in Statement :
fps-deriv: df/dx,
fps-add: (f+g),
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-deriv: df/dx,
fps-add: (f+g),
fps-coeff: f[b],
crng: CRng,
subtype_rel: A ⊆r B,
nat: ℕ,
power-series: PowerSeries(X;r),
infix_ap: x f y
