WebAbstract. We give a new and simple proof of the fact that a finite family of analytic functions has a zero Wronskian only if it is linearly dependent. The Wronskian of a finite family f 1,...,f n of (n − 1)-times differentiable func-tions is defined as the determinant W(f 1,...,f n) of the Wronskian matrix f 1 ··· f n f0 1 ··· f0 n..... WebThen, we determined the first derivatives of the given functions, substitute the functions and their derivatives into the formula for the Wronskian, and obtained that the Wronskian of the given functions is: W (x, x e x) = x 2 e x.
