proposition: Lemma limOfArrowsOut {g : graph} (d1 d2 : diagram g C^op) (CC1 : LimCone d1) (CC2 : LimCone d2) (f : ∏ (u : vertex g), C⟦dob d1 u,dob d2 u⟧) (fNat : ∏ u v (e : edge u v), f v · dmor d2 e = (dmor d1 e : C ⟦ _ , _ ⟧) · f u) : ∏ u, limOfArrows CC1 CC2 f fNat · limOut CC2 u = limOut CC1 u · f u.
proof: Proof. apply (colimOfArrowsIn _ _ CC2 CC1 f fNat). Qed.
