Theorem: Finset.mul_prod_Ioc (LeanCamCombi/Mathlib/Algebra/Order/BigOperators/LocallyFinite.lean)

State before:
α : Type u_1
β : Type u_2
inst✝² : PartialOrder α
inst✝¹ : CommMonoid β
f : α → β
a b : α
inst✝ : LocallyFiniteOrder α
h : a ≤ b
⊢ f a * ∏ x ∈ Ioc a b, f x = ∏ x ∈ Icc a b, f x
Tactic:
rw [Icc_eq_cons_Ioc h, prod_cons]
