Theorem dvcjbr 25690

Description: The derivative of the conjugate of a function. For the (simpler but more limited) function version, see dvcj 25691. (This doesn't follow from dvcobr 25687 because ∗ is not a function on the reals, and even if we used complex derivatives, ∗ is not complex-differentiable.) (Contributed by Mario Carneiro, 1-Sep-2014.) (Revised by Mario Carneiro, 10-Feb-2015.)

**Hypotheses**
Ref	Expression
dvcj.f	⊢ (𝜑 → 𝐹:𝑋⟶ℂ)
dvcj.x	⊢ (𝜑 → 𝑋 ⊆ ℝ)

**Assertion**
Ref	Expression
dvcjbr	⊢ (𝜑 → 𝐶(ℝ D (∗ ∘ 𝐹))(∗‘((ℝ D 𝐹)‘𝐶)))
