∀ {α : Type u_3} {f g : α → ℝ} {t₀ : Filter α},
  (∀ (t : α), 0 ≤ f t) → (∀ (t : α), f t ≤ g t) → Filter.Tendsto g t₀ (nhds 0) → Filter.Tendsto f t₀ (nhds 0)

Special case of the sandwich lemma; see tendsto_of_tendsto_of_tendsto_of_le_of_le and tendsto_of_tendsto_of_tendsto_of_le_of_le' for the general case.
