For the derivative with respect to V, we could use the chain rule along with the matrix calculus result ∂ V ∂ V = adj ( V) = V ⋅ V − 1, where adj denotes the adjugate matrix. From there, mihara machinery works

"WebA determinant is a real number or a scalar value associated with every square matrix. Let A be the symmetric matrix, and the determinant is denoted as “det A” or A . Here, it refers to the determinant of the matrix A. After some linear transformations specified by the matrix, the determinant of the symmetric matrix is determined.
