May 17, 2020 at 14:39	comment	added	Federico Poloni		In my experience, in 99% of the claimed applications of the Vandermonde determinant, one does not actually need the determinant, but only on the fact that the Vandermonde matrix is invertible, and this can be proved directly with a simpler argument: if a row vector is in the left kernel of this matrix, then its entries form the coefficients of a degree-$(n-1)$ polynomial with $n$ distinct zeros.
