##### Abstract

Let $\mathfrak{𝔤}$ be a simple Lie algebra. There are classical formulas for the Jacobians of the generating invariants of the Weyl group of $\mathfrak{𝔤}$ and of the images under the Harish-Chandra projection of the generators of the centre $\mathsc{𝒵}\left(\mathfrak{𝔤}\right)\subset \mathsc{𝒰}\left(\mathfrak{𝔤}\right)$. We present a modification of these formulas related to Takiff Lie algebras.
